6.12.14 Boiler cold start function
Param & Display LoadController ControlParam ColdStart
The boiler cold start function reduces the thermal load of the boiler during burner
start.
If the boiler cold start function is activated and if the boiler temperatures is below
the switch-on threshold set for the boiler cold start function at burner start, the W-
FM carries out a cold start sequence. The burner starts with the lowest burner ca-
pacity. The capacity is increased, either after the residence time set or when the
boiler temperature exceeds the next setpoint step. When the boiler temperature
reaches the switch-off threshold set, the W-FM stops the cold start sequence and
the load control is activated.
