Install Guide CT110

Caution

   

• 

Turn off electricity to the HVAC system

 before installing or 

servicing thermostat or any part of the system.

 • Do not turn electricity back on until work is completed.

• Do not short (jumper) across electric terminals at the control 

on the furnace or air conditioner to test the system. This may 

damage the thermostat.

• All wiring must conform to local codes and ordinances.

• This thermostat is designed for use with 24 volt AC HVAC 

and millivolt gas systems. The thermostat is powered by 4AA 

alkaline batteries and/or 24 volt AC C wire (or a 12-24 AC or 

DC source). Each thermostat relay load should be limited to 1.0 

amp; higher amperage may cause damage to the thermostat.  

• Your thermostat is a precise instrument, handle it with care.

Caution

 

 To avoid electrical shock and 

to prevent damage to the furnace, air conditioner, and 
thermostat, 

disconnect the power supply

 before 

beginning work. This can be done at the circuit breaker.
