2. Thermostat Anticipator Setting
Proper control of the indoor air temperature can only be achieved if the
thermostat is calibrated to the heating and/or cooling cycle. Calibration will
help to produce a more constant indoor temperature by adjusting the length of
the heating/cooling cycle to fit the application. A vital consideration of this
calibration is related to the thermostat heat anticipator.
The proper thermostat heat anticipator setting is 0.1 ampere. To increase the
length of the cycle, increase the setting of the heat scale; to decrease the
length of the cycle, decrease the setting of the heat scale.
Anticipators for the cooling operation are generally pre-set by the thermostat
manufacturer and require no adjustment.
Anticipators for the heating operation are of two types, pre-set and adjustable.
Those that are pre-set will not have an adjustment scale and are generally
marked accordingly.
Thermostat models having a scale as shown in Figure 5 must be adjusted to
each application.

In many cases, this setting can be found in the thermostat installation
instructions. If this information is not available, or if the correct setting is
questioned, the following procedures should be followed:
