SYSTEM OVERVIEWGEN UC

The GEN UC is a microprocessor based, digital communcating controller designed to communicate and control stand alone Gas / Electric or Heat Pump units, either RTU’s or Split type systems, remotely over the internet. The GEN UC will communicate and control up to 20 SA STATS. The communication hub is App based and accessed via mobile phone, or device over local area network (LAN) or the internet.

The GEN UC RM controllers are available and used to expand your system to control multiple stand alone units remotely. GEN UC can support up to 20 RM expansion controllers providing control of up to 400 RTU’s or split systems.

The GEN UC mobile App allows for a wide range of system control and changeover strategies, allowing the contractor to tailor the GEN UC system to a specific application. Additional features include Morning warm up and thermostat lock out. An integrated clock allows for setup, night setback and vacation scheduling, globally or individually for each thermostat, with selectable 2 to 8 hour override, along with a feature to remotely lock each thermostat independently in the system. A unique system tool provides the installing contractor with a simple startup diagnostic to quickly alert and identify any system wiring errors, all from the palm of your hand using the GEN UC mobile App.

The GEN UC communicates to SA STAT thermostats that are universal multi-stage stand alone communicating thermostats for direct control of Gas / Electric and Heat Pump systems. The SA STAT is hard wired to the unit and communicates back to the GEN UC via the RS-485 communiacation link. Each SA STAT is equipped with RA/SA sensors which report system operations to the mobile App, along with Humidity status.

GEN UC is recognized as the industry’s easiest commercial control system to install and wire. The GEN UC system operates over a plenum rated three wire data link, along with two 24vac power wires all daisy chained from SA STAT to SA STAT with no home run wiring required.

DESCRIPTION

The SA STAT (Part# SASTAT) is a universal programmable G/E or H/P thermostat, microprocessor based, auto changeover, stand alone thermostat used to control stand alone units in the GEN UC system. The SA STAT is configured for Gas/Electric (2H, 2C) or Heat Pump (3H, 2C) with selectable fan operation. The SA STAT reports the room humidity, supply and return air temperatures and has a large, easy to read LCD display.

The SA STAT is very easy to configure through the mobile App or by manually adjusting settings at the thermostat.

The SA STAT features an on board thermistor for precise temperature measurement. In the event of power loss, the Heat and Cool set points are stored in non-volatile memory, without the need for battery backup.

Space ambient temperature is continually displayed with large, easy-to-read numbers. The SA STAT temperature display range is 47° - 95°F. Heat and Cool set points and operation modes are all indicated on the display.

Programmed set points can be manually adjusted at the thermostat or electronically locked through the mobile app to provide limited manual set point adjustment. During unoccupied hours, temporary operation can be overridden with a touch of a button.

Sequence of operation

SA STAT– Stand alone ThermostatTo turn the SA STAT on, press and hold the AUTO/OFF button for 15 seconds. When OFF is displayed, press and hold OFF button for 15 seconds until AUTO is displayed,; release button, stat is in AUTO mode. If AUTO is displayed, press AUTO button for 15 seconds until OFF is displayed; release button, stat is in OFF mode.

SA STAT OPERATION

COOL - The thermostat will make a Y1 cool call when the space temperature rises 1° above set point. Y2 will energize when the space temperature rises 2° above the cool set point (2nd stage can be adjusted 2°- 8° for desired staging). When the room temperature reaches set point, Y1 and Y2 will de-energize. O or B energize for the reversing valve circuit, depending on configuration. The G circuit is energized for fan.

HEAT - Gas / Electric - The thermostat will make a W1 heat call when the space temperature is 1° below the heat set point. W2 will energize when the space temperature is 2° below the heat set point (2nd stage can be adjusted 2°- 8° for desired staging). When the room temperature reaches set point W1 and W2 will de-energize.

Note: When the thermostat is configured for GAS operation the fan circuit is not energized in heat mode. When the thermostat is configured for ELECTRIC operation the fan circuit is energized in heat mode.

HEAT - Heat Pump - The thermostat will make a Y1 heat call when the space temperature is 1° below the heat set point. Y2 will energize when the space temperature is 2° below the heat set point (2nd stage can be adjusted 2°- 8° for desired staging). W2 (Aux Heat) will energize when the space temperature is 1° below what the 2nd stage temperature is set for. When the room temperature reaches set point Y1,Y2 and W2 will de-energize.

EMERGENCY HEAT - When Emergency Heat is selected in the configuration menu on the thermostat on a call for heat, there is an output signal on “W2” for backup heat and “G” for the fan. The compressor circuits Y1 and Y2 are locked out during heat calls until the emergency heat function has been turned off in the configuration menu. ( When selected for Emergency Heat, cool calls are not seen by the SA STAT untill the Emergency Heat is disabled.)

FAN MODE - Is factory set for “AUTO”. To configure the thermostat to run the fan constant “ON” you will need to go into the thermostat configuration menu and select Fan Mode and change it from “AUTO” to “ON”.

OVERRIDE - When the system is in the Unoccupied mode, the thermostat provides an adjustable over-ride ranging from 2 to 8 hours for after-hours system operation. To select the override function, press the Auto button and note “Override” is indicated on the left side of the display. When additional override is required, press the Auto button again. (Override is factory set for 2 hours.) To disable override push AUTO button again to return to unoccupied mode.

Installing 24 volt power wiringOnce GEN UC controller and SA STAT’s are installed, install one 24vac 40va transformer, and wire secondary 24 volts to the TR1 / TR2 (IN - A) lower terminals on GEN UC controller. Using 18 ga. thermostat wire, wire TR1 / TR2 (OUT - B) upper terminals and daisy chain power wires to the first thermostat. Continue daisy chain wiring from first thermostat to second, third, etc., until all thermostats are wired with power.Note: Maintain TR1(Hot) and TR2(Common) wiring polarity throughout the system to improve communications.

Installing Communication Wire RS485Once power wiring is daisy chained to all thermostats in the system, use 3- wire plenum rated twisted pair communications wire to install communications link. Install communications wire using the A, B and GND (C) terminals on GEN UC controller and daisy chain to the first thermostat in the system and wire to A, B and GND terminals on the thermostat. Continue daisy chain to the next thermostat using A, B and GND terminals on the thermostat to the A, B and GND of the next thermostat, repeating this process until all thermostats are wired into the communications link. Communications wiring is polarity specific: if RED communications wire is on A at the GEN UC controller, then RED wire is connected to A throughout the system.

The GEN UC mobile App provides local or remote access to your system, providing direct access to stand alone units.

Download and install the GEN UC App on your Android phone or mobile device from the link that was emailed to you or accessed from your phone’s App store. Please contact technical support for the most current App or if you were not sent a link. ( IOS version is under development.)

Connect an Ethernet cable from the customer’s network into the GEN UC’s Ethernet connection (this should be provided by the customer). (Skip the step below if you were able to connect to the customer’s network.)

If you are unable to access the customer’s network, use the stand alone router provided by Zonex.Plug the stand alone router into power with the power supply provided, plug one end of the Ethernet cable (also provided) into the LAN port of the router and the other end into the GEN UC. This will allow you to communicate with the GEN UC so that the startup and configuration changes can be made to the system.

Ensure that your phone is connected to the same network as the GEN UC via a Wi-Fi connection. If you are connecting to the customer’s network then you must obtain the network name /SSID and password (you may need to contact your customer’s IT personnel). If you are connecting through the stand alone router provided by Zonex, the network name/SSID and password is located on the bottom of the router.

Open the Zonex App and press the “SCAN LAN FOR GEN UC” icon at the bottom of the screen.

Allow the App time to scan the network for the GEN UC control board (this could take up to 60 seconds).

You will then see the message “Tap to select your local GEN UC system” at the top of the App. Tap the down arrow on the right, and a drop down menu will appear indicating the GEN UC is connected to the network. If no GEN UC is listed, power off the GEN UC for a few moments, power it back on and reopen the Zonex App so the scan process can be restarted.

Select the GEN UC you wish to access by tapping on it.

Syncing the GEN UC RM to the GEN UC ControllerEach RM controller communicates to the GEN UC over an RS485 communications buss. GEN UC is the communications hub for the system providing time clock functions along with interpreting any calls or system updates at the RM level and communicates that information to the cloud. Each RM controller must be synced with the GEN UC controller to communicate and transmit information to and from the mobile App.

Connect to the GEN UC via the mobile app. Go into the “System Configuration Menu” and select “Configure Number of RM’s Attached to System”. Enter the number of GEN UC RM’s wired to the GEN UC controller.

While still in the “System Configuration Menu”, select “Assign RM ID”. Enter 1 for the first GEN UC RM in the system and press “OK”. When the Blue light starts flashing on the GEN UC RM controller, press and hold the sync button on the GEN UC RM board for 15 seconds. When the light stops flashing the sync has been completed.

Repeat the “Assign RM ID” for each additional GEN UC RM in the system, making sure to increase the RM ID for each GEN UC RM. For example, if you have 7 GEN UC RM’s in the system, they will be ID'd 1-7 in the order of how the communication wire is daisy chained.
