The set time (in seconds) determines the burner cut-in / cut-out when the
boiler / flow temperature is outside the 'Band limit' ID no. 11048.
Two conditions must be met in order to cut-in / cut-out the next burner step:
• the set time has elapsed after the latest burner cut-in / cut-out
• the boiler / flow temperature is outside the band limit
5 ... 6000: Set the desired time.
The upper illustration shows a typical situation for burner step
cut-in after a saving period. The temperature difference between
the desired and the actual boiler / flow temperature is relatively
large, i.e. outside the band limit.
The lower illustration shows a typical situation for burner step
cut-out. The temperature difference between the desired and the
actual boiler / flow temperature is relatively large, i.e. outside the
band limit.
If the 'Max. T limit' (ID no. 11049) has been exceeded, the cut-out
of the burner steps takes place every 5 seconds.
