• This thermostat should only be powered by
4 AA alkaline batteries or a listed class 2 power
supply at 24 VAC (C-Wire or wall transformer).
• An amperage higher than 1 amp to each
thermostat relay load 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. Contact
a local HVAC professional for help.
