Caution
• Your thermostat is a precise instrument, handle it with care.
• 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 3 AA alkaline
batteries and/or 24 VAC C wire (or a 12-24 AC or DC
source) and millivolt gas systems. Each thermostat relay
load should be limited to 1.0 amp; higher amperage may
cause damage to the thermostat.
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.
