Page 3: Step#1: Preparation
Step #1 Preparation • Proper installation of the thermostat will be accomplished by following these step by step instructions. If you are unsure about any of these steps, call a qualified technician for assistance. • Assemble tools. Drill with 3/16 inch Drill Bit (when not Flat Blade Wire cutter using j-box) Screwdriver &... -
Page 4: Step#2: Applications
Step #2 Applications New Applications • Follow the thermostat and E-M (Electro-Mechanical) wiring diagrams supplied with the submittal package, and afixed to the fan coil unit enclosure. Go to pages 6 through 10 for instructions to test operation for the available applications. Existing Applications • Remove the cover of the old thermostat. If it does not come off easily check for screws. • Loosen the screws holding the thermostat base or subbase to the wall and lift away. • Disconnect the wires from the old thermostat. Tape the ends of the wires as you disconnect them and mark them with the letter of the terminal for easy reconnection to the new thermostat. • Keep the old thermostat for reference purposes until your new thermostat is functioning properly. CAUTION: Risk of Electric Shock. CAUTION Disconnect power supply before making electrical connections to avoid electric shock. -

Step #4 Test Operation 4-PIPE SYSTEM • Turn the power on to the Fan Coil Unit. • Press the MODE button repeatedly until the HEAT icon appears on the display. Press the UP or DOWN buttons until the set temperature is 10 degrees above room temperature. The hot water valve will open and the fan will be running. • Press the MODE button repeatedly until the COOL icon appears on the display. Press the UP or DOWN buttons until the set temperature is 10 degrees below room temperature. The cold water valve will open and the fan will be running. - Page 8 Step #4 Wiring Diagram Sample Wiring Diagram S ample Wiring Diagram 4-Pipe, Low Voltage Valves, Duct Temperature Sensor 4-Pipe, Low V oltage V alves, Duct T emperature & Dry Contact Sensor & Dry Contact Important Note: If a Duct Duct Sensor sensor is connected to this G100-71520307 thermostat it is suggested WHITE...
- Page 9 Step #4 Test Operation 2-PIPE, HEAT ONLY OR COOL ONLY • Turn the power on to the Fan Coil Unit and confirm that the thermostat is programmed correctly in setup steps #3 and #4 on page 11 of the Owner’s Manual. • If Heat Only, press the MODE button repeatedly until the HEAT icon appears on the display. Press the UP or DOWN buttons until the set temperature is 10 degrees above room temperature. The hot water valve will open and the fan will be running. • If Cool Only, press the MODE button repeatedly until the COOL icon appears on the display. Press the UP or DOWN buttons until the set temperature is 10 degrees below room temperature. The cold water valve will open and the fan will be running. • Press the UP button until the setpoint is equal to the room temperature. Press the Fan button repeatedly until a single bar appears next to the Fan icon. Confirm the fan is running on low speed. Press the Fan button again, confirm the fan is running on medium speed. Again, press the Fan button, confirm the fan is running at high speed. Press the Fan button once more, the bars next to the Fan icon should disappear.

Page 15: Troubleshooting
Troubleshooting • SYMPTOM: The fan will not run in all three speeds or switches speeds in an improper order. CAUSE: Incorrect wiring between the thermostat and the relay board, or between the relay board and the fan wires. REMEDY: Recheck the wiring (G=low speed, G2=medium speed, G3=high speed). • SYMPTOM: Cold water valve opens for either a cool or a heat demand in a 4-pipe system. - Page 16 Troubleshooting • SYMPTOM: The thermostat display flashes ‘ Occupied 1’ when running the program. CAUSE: The sensor connected to the Dry Contact terminals of the thermostat, is active, forcing the unit into ‘ Occupied 1’ . REMEDY: Verify proper wiring between the thermostat and the occupancy sensor and verify that the wiring is not shorted. If no sensor is connected, program the Dry Contact polarity for Normally Open (step #14, page 21 of the Owner’s Manual). • SYMPTOM: The thermostat will only allow Heat or Off in 2-pipe installations, even though chilled water is available. CAUSE: Faulty, improperly wired, or improperly installed H2O changeover sensor.
