Important Safety Information
WARNING:
•
Always turn off power at the main power source by unscrewing
fuse or switching circuit breaker to the off position before installing,
removing, cleaning, or servicing thermostat.
•
Read all of the information in this manual before installing or
programming this thermostat.
•
This is a 24V AC low voltage thermostat. Do not install on voltages
higher than 30V AC.
•
All wiring must conform to local and national building and electrical
codes and ordinances.
•
Do not short (jumper) across terminals on the gas valve or at the
system control to test installation. This will damage the thermostat
and void the warranty.

OR NEW INSTALLATIONS, MOUNT THERMOSTAT ON INSIDE WALL, 4-5 FEET ABOVE THE FLOOR. DO NOT INSTALL
BEHIND A DOOR
, IN A CORNER, NEAR AIR VENTS, IN DIRECT SUNLIGHT, OR NEAR ANY HEAT OR STEAM GENERATING FIX-
TURES. INSTALLATION AT THESE PLACES WILL AFFECT THERMOSTAT OPERATION.
IMPORTANT: T
HIS THERMOSTAT IS COMPATIBLE WITH 100% LOCKOUT SYSTEMS. TO RESET THE SYSTEM, TURN
THERMOSTAT TO
OFF POSITION FOR AT LEAST 60 SECONDS.
