Releasing and locking a boiler

A boiler can be released or locked either via the digital input (release input) or operation
(boiler operating mode).

Main menu > Boiler > Boiler operating mode

Preselection
With the digital release input, the boiler will stay locked as long as the input is passive.
If the boiler is locked via the release input, setting Frost prot (release input off) can be
used to select whether or not the boiler shall remain off also when there is a heat
request due to frost protection.
• Setting Off: The boiler also remains off in the event of risk of frost
• Setting On: The boiler will be put into operation to ensure protection against frost

The boiler can also be locked depending on the outside temperature:
• The boiler will be locked when the attenuated outside temperature exceeds the
selected limit value
• The boiler will be released again when the composite outside temperature drops
1 K below the limit value
