Installation precautions
• Before installing or servicing the thermostat,
turn off power to the system at the circuit breaker.
• Leave power off until you have
finished installing or servicing.
• Shorting the electric terminals at the control on
the heating or cooling system may damage the
thermostat. Do not test the system this way.
• You must follow all local codes and
ordinances for wiring the system.
• This thermostat should only be powered by two
AAA alkaline batteries or a listed Class 2 power
supply at 24 VAC (C-Wire or wall transformer).
• An amperage higher than 1 amp through
each thermostat terminal may cause
damage to the thermostat.
• Verify that the system is 24 VAC. If the old
system is labeled as 120 or 240 volts or has
wire nuts, the system is high voltage. Do not
install the thermostat to a high voltage system.
