Register 38:
Heating = 0, Cooling = 1
Digital input E2:
Heating = contact closed, Cooling = contact open
Dew point
In cooling mode, dew may form on the cooling register. To prevent this, an information
point is provided to close the cooling valve in the event of condensation. The
information can be written via the S-Bus in conjunction with the Room FBox or
register 39.
Register 39:
Normal operation = 0, Coolingvalve closed = 1
Digital input E2: Normal operation = contact closed,
Condensation
= contact open
Dew point delay
When E2 is configured as dew point, it has a timer before Authorizing again after the
cool dew point alarm valve is removal.
This value may delay in the “Config L79xN” FBox be multiplied with a value of 20 sec.
With this new feature can be avoided, that the cooling valve is always on and off
when the conditions are around the dew point.
