A supply water setting is given here which the controller starts raising according to
the rate set in settings.
The concrete floor must be dried slowly to prevent the concrete from cracking.
The supply water temperature maximum limit. The controller raises the supply water
setting at the set rate to this limit, after which the temperature remains at this level.

Information about the setting:
Constant temperature controller:
The concrete drying function is used in new locations when drying
the concrete floor. The supply water temperature is gradually raised
to the maximum setting. If the valve does not open clockwise, chan-
ge the direction of the valve in device settings (see next page). Con-
crete floor drying cannot be taken into use if the H2 control circuit
has been taken into use.
Drying a concrete floor:
The controller keeps the supply water temperature constant re-
gardless of the outdoor temperature (special use). The factory set
supply water is 15.0 °C, the supply water minimum limit is 5.0 °C, and
the maximum limit is 95.0 °C. The outdoor temperature measurement
can be taken into use (device settings/ measurement initiation).

Special application for the constant temperature controller:
When the controller is being used as a constant temperature cont-
roller, the set temperature for the supply water can be compensated
with the room temperature measurement and the supply water mi-
nimum limit can be raised with the outdoor temperature measure-
ment. (see Device settings/Measur.channels setting). Example: the
swimming pool application. Install the supply water sensor to the pi-
pe going from the heater to the swimming pool. Install the other sur-
face sensor to the water pipe coming from the swimming pool and
connect it to the controller at the room sensor spot. The controller
will correct the supply water temperature with the room compensa-
tion function so that the return water temperature will remain at the
set room temperature. If the swimming pool is outdoors, install the
outdoor temperature measurement. Then you can set the supply wa-
ter minimum limits according to the outdoor temperature to minimi-
ze the freezing risk.
