    Installation Instructions 1. Always turn off power to the air conditioning or heating system prior to installing thermostat. 2. Determine the HVAC equipment type. Compatible equipment a. 1 Stage Heat / 1 Stage Cool Conventional System b. 2 Stage Heat / 2 Stage Cool Conventional System c. 3 Stage Heat / 2 Stage Cool Conventional System d. 1 Stage Heat / 1 Stage Cool Heat Pump System e. 2 Stage Heat / 2 Stage Cool Heat Pump System f. 3 Stage Heat / 2 Stage Cool Heat Pump System 3. Refer to the wiring diagrams to determine the number of wires necessary to install this thermostat. 4. Ensure the power to the air conditioning or heating system is turned off. 5. Remove front of thermostat body from sub-base. 6. Guide thermostat wires through center hole in sub-base. 7. Place the thermostat sub-base against wall in the desired thermostat location. 8. Mark placement of mounting holes as appropriate. 9. Remove thermostat sub-base from wall and install wall anchors as required at mounting hole locations. 10. Re-insert wires through center hole of sub-base and replace sub-base on wall.

Refer to wiring diagrams and wire thermostat sub-base to the attached HVAC equipment. 13. To prevent electrical shorts and potential damage to the thermostat, ensure all of the sub-base wire connections are secure and are not touching any other terminal. Push any excess wire back into wall cavity and insulate wire opening with suitable material. 14. On thermostat body, locate switch SW1 on thermostat circuit board. 15. Set switch SW1-2 to HP for heat pump system or STD for conventional (or Standard) system. For heat pump system, set switch SW1-1 to E/B for heat changeover valve or G/O for cool changeover valve. For conventional (or Standard) system, set switch SW1-1 to E/B for Electric or G/O for Gas. Electric Heat Heat Heat-Cool Heat-Cool Pump O Pump B 16. Attach front body of thermostat to sub-base of thermostat, being careful to align the terminal pins on the front body with the terminal block on the sub-base. 17. Restore system power and continue to Test the thermostat.
