4.190 Release of oil- / gas-fired boiler below the
outside temperature threshold
• The outside temperature for release of the oil- / gas-fired boiler can be defined
Definition of the outside temperature below which the oil- / gas-fired boiler may be put
into operation.
Setting range
--- / -30...30
--- Oil- / gas-fired boiler is always released
The oil- / gas-fired boiler is released when the composite outside temperature lies be-
low the adjusted value. If the outside temperature lies above the adjusted value, the oil-
/ gas-fired boiler is locked.
The switching points for release and locking are separated by a switching differential to
absorb small outside temperature variations.
Refer to "Release of outside temperature" (before operating line 630).
