Auxiliary Heat Differential: This determines how far from the setpoint the temperature has to be before the
auxiliary heat turns on. This is only available for heat pump systems.
Start Delay (Minutes): This item sets the minimum amount of time the heating system must run before the
Auxiliary Heat Stage is used. To use this start delay, EEC must be enabled and Hold must be off.

Anticipator Control
The Anticipator Control settings are used to “anticipate” the need to turn the system on or off before the
temperature is actually at the setting. As humans, we perceive temperature as a combination of heat in the air
and heat radiated from the walls and surroundings. The thermostat also measures a combination of air and wall
temperature. When heating, the air temperature rises faster than the wall temperature. The thermostat will turn
the heat off briefly to prevent overheating the air while the wall temperature catches up.
When cooling, the thermostat will periodically run the cooling system to circulate the air and remove humidity
when the temperature is close to, but not above the desired cool setting.
Because of the PID algorithm and auto balance routine which monitors the performance of the HVAC system,
the anticipator settings are automatic by default. However, the anticipator settings may be adjusted if desired.
Heat Anticipator: This adjusts the tendency of the thermostat to turn the heating unit off before the desired heat
setting is reached. This is done to avoid overheating the air while the walls and furniture catch up. A setting of
0-4 is intended for fast reacting heating systems, such as forced air. A setting of 6-10 is intended for slow
reacting heating systems, such as radiant heat. A setting of 5 is used for automatic anticipation.
A lower setting will decrease the tendency to turn off the heating system before the desired heat setting is
reached. If the heating system response time is slower, as are most radiant heating systems, a higher number
will help maintain an even space temperature.
Cool Anticipator: This adjusts the tendency of the HVAC to run the cooling system to refresh and dehumidify
the air before the temperature rises to the desired cool settings. A setting of 0-4 is intended for more humid
climates and will increase the tendency for the cooling system to turn on to refresh and dehumidify the air. A
setting of 6-10 is intended for dry climates and will decrease the tendency to run the cooling system below the
cooling setting. A setting of 5 is used for automatic anticipation.
