WARNING

Important Safety Information

 

Read this manual thoroughly prior to installing, programming or operating the wall thermostat.

 

Do not use this wall thermostat with voltages above 24 Volts DC and 1 amp current.  This wall thermostat
is a DC dry contact system that will turn gas appliances on or off.

 

Wiring must conform to appliance requirement and building codes/ordinances as required by local and
national code authorities having jurisdiction.

 

This wall thermostat should only be used as described in this manual.  Any other use is not recommended
and will void the warranty.

NOTE

Due to the sensitive temperature monitoring components in the wall thermostat,  it is
necessary to allow the wall thermostat to stabilize to room temperature before accurate room
temperatures are displayed.  If the wall thermostat is activated from a severe cold condition,
allow 15 minutes for accurate temperature readings to appear on the LCD.

WARNING

Turn appliance OFF and allow to cool before installing or servicing.  DO NOT connect
110-120 VAC wiring directly to the wall thermostat.    Read all instructions completely before
attempting installation.  Follow instructions carefully during installation.  Any modification of
