This function is only possible with modulating boilers and sequential mode. When no heat generator is requested to switch on or off while the time of OPM-01, the last boiler of the sequence will switch off. This feature is used to meet the required heating load with a minimum number of operational heat generators. To disable this function the parameter OPM-01 must be set to the value “0”.
