110 Operating the Boiler
* The anti-fast cycling time is the duration that the boiler
stops its space heating operation when the space heating
supply or return temperatures reach the set values for
boiler operation stop temperatures. The boiler will not
resume space heating until the duration elapses, even
when the space heating supply or return temperatures
return to within the set ranges.
** Boiler Pump Delay is the duration the circulation pump
continues to run between the space heating supply
or return temperature reaching the set point and the
burner turning off. If the space heating supply or return
temperature remains outside of the boiler operation
temperature range for a set period, the pump stops for 10
mins, runs again for 5 mins, and then repeats the cycle.
