Once the furnace is installed, check the thermostat anticipator the proper nominal setting.
a. Connect a multimeter, capable of reading milliamps (mA), in series with the low voltage
wires to the thermostat.
b. Increase the thermostat setting, or create a “call for heat”.
c. Read the value of the thermostat current, in milliamps.
d. Adjust the heat anticipator of the thermostat to the value read by the multimeter.
If the heat anticipator is set too high, the furnace may delay activation of a heating cycle for
too long. If the heat anticipator is set too low, the furnace may cycle too frequently. Either
condition may not provide optimal comfort to the homeowner.
