to prevent drafts.
To avoid fire, shock, or death, 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, or at the
appliance.
Your thermostat is a precise instrument, handle it with care.

Do not turn electricity back on until work is completed.

WARNING–Risk of Fire or Electric Shock
Do not short (jumper) across electric terminals at control on

furnace or air conditioner to test the system. This will damage the
thermostat and void your warranty.
All wiring must conform to local codes and ordinances.

This thermostat is designed for use with 24 volt AC systems. The
•
thermostat should be limited to a maximum of 1.0 amps; higher
amperage may cause damage to the thermostat.
