IMPORTANT NOTES: This operating mode requires adaptations in the boiler house.
In any case, however, suitable action must be taken to ensure that the temperature
of the coolant is above the dewing point of the room air to prevent condensation on
the radiator surface.
This "dry cooling" allows reducing very high room temperatures by several degrees. How-
ever, this does not allow cooling to room temperatures of e.g. 22°C.
For effectively operate dry comfort cooling we recommend exchanging flow and return
flow. This can easily be done with our accessories (cross piece).
CAUTION: If no exchange is made, performance reductions of up to 50% must be ex-
pected.
