THERMOSTAT INSTALLATION

Leveling Thermostat
Leveling is for appearance only and 
will not affect thermostat operation.

WIRING 

Refer to equipment manufacturer’s instructions for specific system wiring information. After 

wiring, see INSTALLER MENU for proper thermostat configuration. Wiring table shown are 

for typical systems and describe the thermostat terminal functions. 

WARNING

!

Do not use on circuits exceeding specified voltage. 

Higher voltage will damage control and could 

cause shock or fire hazard. 

Do not short out terminals on gas valve or primary 

control to test. Short or incorrect wiring will burn 

out thermostat and could cause personal injury 

and/or property damage. 

CAUTION

!

To prevent electrical shock and/or equipment

      damage, disconnect electrical power to system,  

at main fuse or circuit breaker box,until 

installation is complete. 

Precautions

•  Do not exceed the specification ratings.

•  All wiring must conform to local and national electrical codes and ordinances.

•  This control is a precision instrument, and should be handled carefully. Rough handing or 

distorting components could cause the control to malfunction.
