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 24 3 Stage Extended On When enabled and if
