1. Control panel

Optima 170 The domestic hot water heat pump Vanvex R/RS is de-livered with an Optima 170 control, which has a factory setting meaning that the heat pump is ready for operation without additional adjustments.The factory setting is a default setting that should be adjusted to the operational needs and requirements for the dwelling in order to achieve optimal performance and utilization of the system.

1.1 Operation

User Menu The set point of the relevant menu item is displayed when the key/key combination is pressed.The value can be changed with the arrow keys when the key/key combination is held down simultaneously.

P1: Level (The “level” key is pressed and held. Then the setting can be changed with the arrow keys).With this key it is possible to switch between: Standby, automatic operation, constant operation and timer con-trolled constant operation (level 0, 1, 2, 3). • Level 0: The heat pump is now turned off and only the

controller is active. The heat pump does not turn on when there is a need for heating.

• Level 1: The fan only runs when the domestic water is being heated. In menu item E25 the desired fan speed is set between 0-100 %.

• Level 2: The fan runs, even when the compressor is shut down. This function is called: Constant extraction from the dwelling. In menu item E25 the desired fan speed is set between 0-100 %.

• Level 3: The fan runs in a chosen period of time, even after the compressor has stopped, before it switches back to normal operation.

In menu item E25 the desired fan speed is set between 0-100 %. In menu item E17 it is selected whether “Level 3” is to run until the next manual change (E17 = 0) or if “Level 3” is to be active in a limited period of time (E17=1 and E18: 0-10 hours) and then return to “Level 2”.Options: 0-3Factory setting: 1

P2: Controlling the immersion heater (The “immersion heater”-key is pressed and held. Then the setting can be changed with the arrow keys).The heat pump is supplied with an immersion heater for heating of the domestic water.At outside temperatures below 0°C it is benefi cial to use

the immersion heater as a supplement to heating the domestic water.

1 = the immersion heater is in operation when there is a need (see set point P5).0 = the immersion heater is not in operation, even though there is a need.Options: 0-1 Factory default: 0.

P3: Operating thermostat (The “operating thermostat”-key is pressed and held. Then the setting can be changed with the arrow keys). Domestic water is heated by the heat pump. The compres-sor starts if the T8 temperature (boiler, bottom) becomes lower than set point P3 minus 5°C and stops again when the T8 temperature is equal to set point P3. Options: 0-55 °C. Factory setting: 52 °C.

P4: Stop defrosting (The “Level”+ “Operating thermostat” keys are pressed and held simultaneously).Defrosting period normally stops when the evaporator has reached a temperature of 10°C. Under special conditions it may be necessary to change this temperature setting.Options: 0-25 °C. Factory setting: 10 °C.

P5: Immersion heater (“Immersion heater”+ “Operating thermostat” keys are pressed and held simultaneously).The immersion heater only heats the upper half of the boiler, while the heat pump continues heating the bottom part of the boiler. The immersion heater starts if the T7 temperature (boiler top) is lower than set point P5 minus 5°C. The immersion heater stops again when the T7 tem-perature is higher than set point P5.Options: 0-65 °C. Factory setting: 50 °C

Display view (main menu) By pressing the arrow buttons the different temperatures will show in the display. Press until the number of the sen-sor of the desired temperature is displayed. After approxi-mately 3 seconds the temperature is displayed. The tem-perature remains for about 30 seconds before the display goes back to normal view. Normal view is set in menu item E49 (blank display, water temperature T7 or clock).

The following values can be displayed:T4/T10: “Forced operation” input (cannot be used for temperature display). When short circuited, the heat pump goes to forced operation.T5: Before evaporatorT6: EvaporatorT7: Boiler, topT8: Boiler, bottomT9: Additional sensor (can be used as solar panel temperature sensor) CL: The current time from the built-in clock.


1.2 Altering settings in the operating

menu

Press the “Arrow up” and “Arrow down” simultaneously for approximately 10 seconds to enter the operating menu. The display now shows the fi rst menu item E0 in the oper-ating menu. If a key is not activated for about 15 seconds while in the operating menu, the operating menu shuts down automatically and the control returns to the main menu.A desired menu item E? can be reached by scrolling up and down with the “Arrow up” and “Arrow down” keys. The value of the menu item is displayed when you press the “Operating thermostat”-key (the key to the right under the display).The value can be changed with the “Arrow Up” and “Ar-row down” keys, when the “Operating thermostat”-key is pressed down simultaneously. When the desired value is reached, release the “Operating thermostat”-key and you will return to E?.

1.3 Operating menu

The pump stops again when the T9 temperature (solar panel) becomes lower than the T8 temperature (boiler, bottom). This feature is independent of the heat pump run-ning.Value 2: The underfl oor heating function, which activates the circulation pump (relais R9). If the T8 temperature (boiler, bottom) is higher than the setting in menu item E13 (underfl oor heating temperature), the underfl oor heating function is activated. The pump will run, if the T9 tempera-ture (solar panel) is lower than the setting in menu item E2. The pump (relais R9) stops again when the T9 tem-perature (solar panel) is higher than the setting in menu item E2. This feature is independent of the heat pump running.Value of 3: The solar panel function (special RS func-tion) which activates the solar pump (relais R9). The solar panel function has an overall safety feature that can turn off the solar pump. If the T9 temperature (solar panel) is higher than 89 °C, the pump is turned off. The pump starts again if the T9 temperature (solar panel) is less than 87 °C. If the T8 temperature (boiler, bottom) is less than the set point in menu item E46 (max. boiler temperature), the solar pump function is activated. The pump will be running if the T9 temperature (solar panel) is higher than the T8 temperature (boiler, bottom) + menu item E20 (solar panel hysteresis).

The pump (relais R9) stops again when the T9 tempera-ture (solar panel) becomes lower than the T8 temperature (boiler, bottom).

When the pump relais R9 is activated, the heat pump and the immersion heater switches off. After the pump relais R9 is deactivated, 15 min. will pass, and the following hap-pens: • If the T5 temperature (before evaporator) is greater than 5.5 °C, the heat pump is started. • If the T5 temperature (before evaporator) is lower than 4.5 °C, the immersion heater is started.

Value of 4: The cooling function which activates a three-way damper, which directs the cold exhaust air to a room with cooling requirements. This feature is controlled by the temperature set point in menu item E2 and the T9 sensor:

• If the T9 temperature is higher than the set point in menu item E2, relay R9 switches on. • If the T9 temperature is lower than the set point in menu item E2, relay R9 switches off. This feature is independent of the heat pump running.Value 5: The cooling function which activates a three-way damper, which directs the cold exhaust air to a room with cooling requirements. This feature is controlled by the temperature set point in menu item E2 and the T9 sensor, but opposite menu item E19 = 4:

• If the T9 temperature is higher than set point in menu item E2, relay R9 switches off. • If the T9 temperature is lower than set point in menu item E2, relay R9 switches on. This feature is independent of the heat pump running.Value 6: Relay R9 is ON, if the compressor is running and OFF if it is not running. This feature is independent of the heat pump running. Options: 0-6 Factory setting: 0

The defrost function is running according to the table for

defrosting above. If the T5 temperature (before evapora-

tor) is equal to a temperature in the table (e.g. 3°C), then

the defrosting will start, if the T6 temperature (in evapora-

tor) goes below the temperature “T6 in evaporator”.

E.g. if T5 is 3 °C, then defrosting will start, when T6 is

equal to -6 °C.

When the defrosting function is active, relay R4 (defrost-

ing) turns on and the fan stops. The defrosting function

can run maximum 30 minutes at a time. The defrosting

function must be disabled for another 60 minutes, before

it can start again.

The defrosting function stops immediately if the T6 tem-

perature (in the evaporator) is higher than the setting in

P4.

2. FunctionThe fl ow chart in the installation instructions shows where the sensors are located, and relay outputs are shown on the control print, as well as the other outputs for turning on the fan and control panel.

2.1 Controlling Optima 170 Domestic hot water heat pumpThe domestic hot water heat pump is a complete unit with a 285 litre hot water boiler, fan, heat pump and complete automation. The unit is used exclusively for heating dome-stic water within the set temperature limit.

Performance The domestic hot water heat pump can heat 367 litres of water from 10 °C to 52.5 °C within 11.5 hours at an extract air temperature of 7°C. The heating time always depends on the temperature of the cold water supplied to the boiler, the extract air temperature and the tap pattern. The immer-sion heater of 1.5 kW can be activated if there is a need for extra hot water.The domestic hot water heat pump only consumpts appr. 28% power compared to a conventional electrical water heater.

The function of the heat pumpThe control starts the compressor shortly after you have tapped hot water. The compressor runs, until the whole boiler has reached the set temperature. Normally, the do-mestic hot water heat pump is able to produce enough hot water to cover an entire family’s hot water consumption.

Water Heating When tapping hot water, cold water is supplied to the boiler in the bottom. A sensor measures the temperature in the bottom of the boiler. When the temperature has dropped 5°C below the set temperature, the compressor starts and the fan blows air through the evaporator. When the water is heated to the set temperature, the compressor (and fan) stop again.

Fan operationThe fan can continue to run, even when the compressor has stopped. Select level 2 or level 3.This function is used when a domestic hot water heat pump is used for extracting air from the wet rooms in the dwelling.As long as input to T4/T10 is short circuited, the control is forced to run level 3. This can be used to get extra extrac-tion from e.g. the bathroom while taking a shower. When the input is no longer short circuited, the controller will go back to the level it came from before short circuiting.

Defrosting When ice formation occurs on the evaporator, the tempe-rature difference between the temperature before the eva-porator and the temperature in the evaporator is too high and the system will begin the defrost cycle (see 1.5 table for defrosting, p. 7). The solenoid valve MA4 opens and the fan stops, until the ice has melted and the evaporator has reached a temperature of appr. 10 °C (depends on the setting in menu item P4). Then the solenoid valve closes again and the fan starts.


2.2 Additional capacity

If the situation arises where the domestic hot water heat

pump is not able to provide enough hot water, you can

activate the built-in immersion heater. Twice as much

water can now be heated. You can set the temperature to

which the immersion heater is to heat the water.

Only use the immersion heater if necessary. The immer-

sion heater consumpts more energy than the compressor.

The immersion heater can be activated manually on the

control panel.

2.3 Reliability

High pressure switch

In order to ensure that the compressor does not run bey-

ond its scope there is a built-in high pressure switch which

shuts down the compressor when the pressure becomes

too high.

The text ”PE” is shown in the display.

When the cause of the error is found, the power has to be

disconnected 10 seconds in order to reset the pressure

switch, before the unit can be restartet.

Lower the water temperature if necessary 2-3°C to avoid

the recurrence of pressure switch error.

Safety breakers

In the event of a failure on the immersion heater, the

safety breakers will shut down the unit. To re-activate

the safety breakers, press the button in the centre of the

breakers.The safety breakers are positioned in the centre

of the boiler.

Remember to disconnect the power to the unit before

carrying out any repairs on the unit.

Repair of the unit should only be carried out by

authorized personnel.

2.4 Alarms

High pressure switch alarm

When the high pressure switch shuts off, the text ”PE” ap-

pears in the display. By reactivation the power to the unit

must be switched off for 10 seconds and then turned on

again. The “PE” error disappears from the display.

3. MaintenanceTo achieve optimal performance, please follow the points

below:

Before the unit is opened, disconnect the power/

unplug and wait until the fan stops.

A few days after the initial setup, check the installation for

leaks in the water installation or blockage of the conden-

sate drain.

Environmental requirements

When repairing or dismantling the domestic hot water heat

pump please follow the environmental regulations and legal

requirements in relation to recycling and disposal of

materials.

3.1 Connection to computerIn order for the Optima 170 to be able to communicate

with the computer system, a communication box ”Genvex

data logger” is to be installed between the control and the

computer system. Genvex data logger is accessories and

can be purchased from Genvex A/S.

3.2 Cooling System and Fan

Fan

Servicing primarily consists of periodic cleaning of the

evaporator.

Remove the top plate of the unit. Clean the evaporator

and fan with brush or a bottle brush.

Be careful not to remove balance weights on the fan wheel

during this process, as this will cause an imbalance and

lead to a higher noise level as well as wear and tear on

the fan.

Risk of injury from sharp slats. The slats must

not be damaged.

Condensation and condensate drain

Together with inspecting and cleaning the fan, the conden-

sate tray shall be cleaned of dirt.

Fill water into the condensate tray and see if the water

fl ows freely. If not, then drain must be cleaned.

Check also whether the evaporator slats are clean.

3.3 Water circulation and boiler

Pressure relief valve

Your installer has installed a pressure relief valve close the

cold water connection of the domestic hot water boiler to

protect the boiler against over pressure when the domestic

water expands during the heating process.

The back pressure valve (check valve), which is installed

in front of the pressure relief valve on the cold water pipe,

prevents water from fl owing back into the cold water pipe.

Therefore the pressure in the boiler rises to the maximum

setting of the pressure relief valve and the pressure relief

valve opens. The redundant water runs away. If the pres-

sure relief valve did not open, the boiler would burst.

The pressure relief valve must be inspected several times

a year. It is tested by pressing the lever on the pressure

relief valve to ensure that the water can run out. Damage

due to a faulty pressure relief valve is not covered by the

warranty.


Anode

In order to prevent corrosion of the enamelled water tank,

a magnesium anode with 3/4” RG is installed in middle of

the boiler.

The anode has a life expectancy of approximately 2-5

years depending on the water quality.

It is recommended that the anode is inspected every

two years.

• Shut off the cold water

• Connect a hose to the drain valve so the water from

the boiler can run into the nearest drain

• Turn on the hot water (to avoid under pressure in the

boiler)

• When the anode is free of water, it can be removed for

inspection.

The anode shall be replaced, if corroded and the diameter

is about 6-10 mm.

Procedure for assembling the unit:

• The anode is mounted

• Shut off the hot water

• Disconnect the hose from the drain valve

• Turn on the cold water

• When the boiler is fi lled with water, the front panel can

be mounted

• Connect power to the unit

3.4 Disassembly/decommissioning

The following must be done:

The unit must be disconnected from the power - i.e. the

electrical wires removed.

Remove the water and heating pipes and empty the water

out of the boiler.

Shut off the cold water supply and attach a hose to the

drain valve, so the water can run out to the nearest drain.

Remove the air ducts and close all supply and extract air

valves so that no condensation forms in the ducts.

4. TroubleshootingThe domestic hot water heat pump is equipped with the

following safety equipment:

4.1 High pressure switchThe high pressure switch protects the unit against too high

pressure in the cooling circuit. In case of disturbances

caused by the high pressure, the pressure switch will stop

the compressor and the domestic hot water heat pump

stops.

The text ”PE” is shown in the display.

When reactivating, the the power to the unit shall be shut

off for 10 seconds and turned on again.

4.2 Safety breakers for immersion

heaterThe safety breakers protect the domestic hot water instal-

lation against too high temperatures during heating with

the immersion heater. The safety breakers are mounted

on the immersion heater. The corresponding sensor is in

the sensor pocket of the immersion heater.

If the set value (80°C) is exceeded, the immersion heater

will disconnect. The immersion heater can be reactivated

when the temperature is below 80°C. To do this, the power

to the unit must be switched off, the front panel dismant-

led, and the front cover of the immersion heater dismant-

led. Then the reset buttons can be pressed.

Be careful not to damage or tear the cables to the control!

4.3 The heat pump does not run

Check out the following:

• Is the system connected to power?

• Is there power at the wall socket?

• Is the heat pump switched off via the temperature sensor

T8?

• Is the water temperature >55 °C?

• Is the cable between the control and the panel mounted?

If it is not one of the above errors, please contact:

• In the warranty period (0-2 years):

The installer, from which the unit was purchased.

• After the warranty period (2 years ->) :

The installer from which the unit was purchased or

Genvex service centre (tel.: +45 7353 2765).

Please have data from name plate ready (silver plate on

the unit).
