3.2 Menu system

3.2.1 Levels

Access to data is hierarchically divided between three levels: Operating level (level 0) Configuration level (level 1) Systemparameter level (level 3) At operating level, the end user can read and alter current plant values, statuses, reference values and time programs without having to specify a password.

By entering an approved password, access is gained to the configuration level, where it is possible to read and alter all values that are accessible at both configuration and operating level.

The parameter names are designations that describe the relevant parameter and that usually comprise composite abbreviations.

Examples. Actsetp Actual setpoint

The parameter names are followed by values that can be read and altered.

3.2.2 Password

The password function protects against access to data and comprises four digits that can be altered if necessary. The predefined password to access the configuration level (level 1) is: 1000 The predefined password to access the systemparameter level (level 3) is: 2000

After accessing the configuration level, the user can alter the password by selecting �Change password� under the �Password� function row. Level 2 and 4 should be used for user defined passwords to have the predefined password left. The password level below the level used for entering the system can be changed If the factory-set password is altered, the predefined password is no longer present. To reset the password, a higher password is required. Contact the supplier.

3.2.3 Menus

In the parameter overview section and in the description section, a grey-marked row provides information about the selected menus that lead from the start page to the parameter names or settings rows. Depending on the type of configuration, some parameters/menus are not used and consequently they are not displayed in HMI. The parameters/menus that are listed and described in this basic documentation retain the same order, however. Some parameters also have different options depending on the configuration.

4.2.4 Example Time switch program

As the day program applies to all days, it is possible to both give consideration to and utilise the times when setting the week program and year program. Activation is set to Actv for the switching occasions that are to apply. Example of a possible setting of a week program with a 2-speed fan:

Weekdays: 07:00...10:00 St1, 10:00...20:00 St2 (apart from Wednesdays) Wednesdays: 12:00...21:00 St2 Saturdays: 05:00...14:00 St1 Sundays and other times unit switched off.

The day program is set at the most widely used time (07:00 St1, 10:00 St2, 20:00 Off) Switching alternative

Switching time Operating method

Activation

T1 07:00 St1 Actv T2 10:00 St2 Actv T3 20:00 Off Actv

The week program is set for all exceptions from the day schedule. Wednesdays (12:00 St2, 21:00 Off) As the day program always starts the unit at 07:00, consideration must first be given to that time and only then may an exception be made in the morning. The Starting time must then be some time before the starting time for the day program. The day program is then used in the day and a new exception made in the evening in order to achieve extended operation. The Starting time for extending a similar operating stage to the day program can then start at some time during the time of the day program. No time for Stop is required as the day program takes over immediately at the closing time for the exception and the day program�s setting at this time is already Off. Saturdays (05:00 St1, 14:00 Off), Sundays (Off) As the day program first starts the unit at 07:00 and then also sets the unit to St2 10:00, an exception can then be made for the whole of the Saturday�s operation. Finally, a new exception must be made at the same time as the closing time for the exception before in order for the unit to stop at 14:00, the exception can also be the whole of the Sunday as the unit should be Off from Saturday 14:00 to Monday 07:00. The Closing time for the Sunday must then be after the closing time for the day program.

4.2.5 Override time switch program

Menu / Scheduler / Override For easy stop and start of the unit or to control the unit from a BMS system, the time switch program can be overridden instead of change in the time program. When the unit is overridden it remains in the desired position, until it sets back to �Auto� and the time switch program has the control again. Operating switch (Opmodeswi)

Overriding the time program, in order to stop or start the unit in the selected position. In auto mode the unit is placed in operation in accordance with the time program, in other modes the time program is overridden to the desired position. However, night mode, control inputs and the service switch on HMI have a higher priority than the operating switch. Displayed at the �Serviceswitch� as �Manu� when override. BMS override

The time switch program can be overridden via communication from a BMS system. This parameter shows the actual state, controlled from the BMS system. In auto mode the unit is placed in operation in accordance with the time program, in other modes the time program is overridden to the desired position. However, the operating switch, night mode, control inputs and the service switch on HMI have a higher priority than BMS override. This parameter can be reset to Auto from the HMI if the communication to the BMS system goes down. Contact the manufacturer for a higher password.

4.2.6 Current scheduler

5.1 Functions, Configuration

The following parameters are also present at a Commissioning guide that may be used at a first configuration. The guide is displayed at the start page if a configuration not has been done. The guide contains besides the following parameters also settings for Language, HMI type and Time adjustment, see separately sections for those settings. Menu / Configuration / Functions Settings for control function, type of fan, damper, heating, heat recovery and cooling, and selection of alarm and sensor inputs.

5.1.1 Application

The application is prepared to handle several variants, with various function set-ups depending on variant. Only one variant is available in this version. Macro 1 Air handling unit with separate starting of supply and exhaust air fans,

separate analog outputs for frequency controller. Three control sequences.

5.1.2 Configuration of temperature control (Control mode)

Adaptation of the regulator for different types of control. This applies to the choice of main sensor, which can be a room sensor/unit, exhaust air sensor or supply air sensor. When selecting cascade control, it is also necessary for room or exhaust air sensor to be selected. When selecting constant supply air control, a room or exhaust air sensor can be used for measurement/night operation etc. or can be deactivated. Three different control modes can be selected:

Cascade control with limits for the supply air temperature. Constant supply air control. Climate adapted Cascade+Supply air control. Cascade control in summer and

constant supply air control in winter. It is also possible to select between two different types of cascade control, see section �Min/Max supplytemperature� for settings options of fixed or sliding limitation (differential temperature control). When selecting cascade control and a fault occurs in the main sensor or if a mainsensor is missing (room/exhaust air sensor), supply air temperature control is activated automatically to ensure that incorrect control values are not obtained. Main sensor is selected automatically but if both a Roomunit and an Exhaust air sensor is activated, then the main sensor can be selected in section �Cascade control�.

Control function 1 � Cascade control

In the case of control mode 1, the room temperature is maintained at a constant level. The control loop for the room/exhaust air generates the set point for the control loop for the supply air. The supply air temperature regulator then controls the output signals for the relevant heating/cooling sequences. The limits for the supply air temperature (Min temperature and Max temperature) guarantee that the supply air temperature is maintained within the set range. Can be selected with fixed or sliding limitation (differential temperature control). Control function 2 � Supply air control

In the case of supply air temperature control, the supply air temperature is maintained at a constant level. Control function 3 � Cascade+Supply air control

In the case of Cascade+Supply air control, the temperature is controlled by a cascade controller in the winter and a supply air controller in the summer. Can be selected with fixed or sliding limitation (differential temperature control). See section �Cascade control� for switch-over conditions.

Settings to configure cooling optimally. Activate cooling

The cooling sequence is blocked at a lower outside temperature than the set value. The cooling sequence is always active if an outside sensor is missing. Max limit cooling at low speed

The cooling control signal is limited when the fans run at low speed. Start DX-cooling stage 1 and 2

Setting when DX-cooling stage is to be started. Not valid for DX-binary Stop DX-cooling stage 1 and 2

Setting when DX-cooling stage is to be stopped. Not valid for DX-binary Min time for restart of DX cooling

Delay before restart of DX cooling may take place. This delay avoids unnecessary switching of the DX steps off and on. This parameter is valid for all DX steps.

5.5.2 Heat recovery

Menu / Configuration / Control parameters / HRC

Depending on the selected function direction for output signal (damper or HRC) and measured difference between outside and room temperature, heat recovery is controlled optimally. Start-up time for heat exchanger

By controlling the exchanger to 100% at start-up, the exhaust air fan heats the heat exchanger, thereby preventing a cold shock in the water battery. When the unit is started at an outside temperature colder than 12oC or if an outside sensor is missing, the output signal is set to 100%. The heat exchanger returns to automatic mode, when the supply air fan has started and the selected start-up time has elapsed.

Activation of cooling recovery

Parameter for activation of cooling recovery. Cooling recovery means that, in the event that cooling is required and if the outside temperature is higher than the exhaust air temperature, recovery (heat exchanger) starts at full power in order to utilise the cooling energy from the room. The outside temperature is compared to the room/exhaust air temperature. When the outside air is warmer than the room air, the mixing damper is closed to the min limit, alternatively the HRC system is controlled 100%. If the outside air is colder than the room air, the mixing damper and the HRC system are controlled in the normal way.

Mixing damper or HRC system Room/exhaust air sensor and outside temperature sensor Parameter Cooling recovery set to �On�

Setpoint for protection against frosting

To protect the recovery circuit against icing, there is a built-in control function that, via a temperature sensor in the used air or the return line (when liquid-borne recovery is selected), ensures that the heat exchanger is defrosted. At low temperatures, the output signal to the heat recovery is reduced in order to defrost the heat exchanger. In the event the temperature falls even more, an alarm is generated (see Alarm frosting). When the Set point is achieved, the exhaust air is transported away immediately in order that the temperature at the exhaust air duct can increase again, thereby preventing icing.

Activate by set the parameter Multifunction input 1 to �HRC Frost�. Setpoint for frosting alarm

If the temperature drops below the set alarm value, a frost protection alarm is generated (see above). Max control signal at defrostning

If heat exchanger pressure switch is activated and this trips, the control signal to the heat exchanger will be decreased so that defrosting can take place. For on/off-rotor, the time for which the rotor rotates is limited. If the parameter is set to zero, the rotor stops entirely in the event of a tripped pressure switch.

Activate by set the parameter Multifunction input 1 to �Press grd�. Min. outside air volume at return air damper

The minimum outside air volume that is mixed with the return air is set with this parameter in the event that heat recovery is required. In the event a unit has stopped, the damper closes fully against outside air.

Start-up time return air

When the pre-heating time has expired, the fans start with outside and exhaust air dampers closed (full return air) for a set period of time (Start-up Time). This prevents cold outside air from blowing in at low outside temperatures.

Output signal for cooling is blocked The pump in the heating circuit is running Start-up of fans activated

The start-up time must be set higher than 0.0. In the event of plants with outside temperature sensors, the start-up control is

only activated at outside temperatures below 15°C. At outside temperatures above 15°C, the plant starts up normally, whereupon the damper can be controlled in the normal way.

In the event of start-ups caused by �Unoccupied heating� or �Night cooling�, there is no start-up control.

Only activated after a pre-heating time The recovery function (heat exchanger) must be set at the return air damper

5.5.3 Heating

Menu / Configuration / Control parameters / Heating

Settings to configure heating optimally. Preheating time

Water-heated air heaters are sensitive to frost. If the air conditioning unit is switched off at night and there are low outside temperatures at start-up, the sudden supply of cold outside air would cause the water in the pipes to freeze. This problem is particularly tangible in conjunction with 2-position dampers. In order to circumvent this, the water circuit is preheated with hot water before the outside and exhaust air damper is opened. At start-up, only the air heater�s heating circuit pump starts and the heating valve opens depending on the prevailing outside temperature for an adjustable period of time. The risk of freezing damage is eliminated, and the unit then switches to normal control. NOTE! When using a long pre-heating time, the result may be the opposite, i.e. the heater battery may get too warm, which causes the heater battery and the heat exchanger to close at start-up, since there is no longer any heat demand. This may cause great variations in the start-up.

The pump in the heating circuit is running The valve opens to 100%. Outside temperature sensor connected Preheating time > 0.0 s Outside temperature < 5 °C

Min. temperature air heater (water) during operation

Setting to prevent triggering of the frost protection. When there is a danger of the heater battery freezing, the sensor in the water return causes the valve actuator to open. This reference value is activated when the unit is in operation.

Keeping the air heater (water) warm when stopping

In the event of a stopped unit, the temperature in the air heater is controlled to the set point in order to prevent frost formation and make it easier for the unit to start up. Setpoint triggered frost protection

If the temperature is below the set freeze limit, an A alarm is obtained, which also stops the unit. Max signal stage 1 and 2

Change between cascade/supply air control

With control type Casc/Supply (cascade control and supply air control) selected, the control types will shift depending on the outside temperature. To avoid pendulating between the control types, a selectable time must elapse before the change-over takes place. Cascade control normally use a higher setpoint than supply air control, therefore it is possible to compensate the basic setpoint for the cascade control when shifting to supply air control to avoid manually adjustment. In order to get the best result, the outside sensor should be placed on the facade and not in the outside air duct, where the sensor may be warmed up when the unit is switched off. Temperature compensation

When shifting to supply air control, the basic setpoint compensates to the set value. This parameter can also be found under section Setpoints. Change-over at set outside temperature

When the outside temperature falls below the set value, the control type changes to supply air control after a preset time. Change-over time delay
