Digit SE minimum supply air temperatures during heating period in
underfloor heating connection
Preheating
DIGIT SE can be equipped with an automatic system that is suitable for controlling
externalpreheating.
The function is installed at factory, and it has to be ordered separately. The preheating
radiator A is installed in the outdoor air duct B. It is switched on before the supply air fan
stops. The operation is controlled by the same sensor located in exhaust air that also controls
the stopping of the supply air fan. The heater is switched on at a temperature higher than
the stopping temperature (factory s6
°
C). If preheating cannot keep exhaust air
temperature warmer than the stopping temperature, the supply air fan stops. When the risk
of freezing has passed, preheating is switched off and the supply air fan starts automatically.
The power of the VALLOX 1000 supply air heater is 1000W. The preheating automatic
system can control the power of 2000W at most.
The VALLOX 1000 supply air heater has to be installed in accordance with the instructions
printed on the cover of the heater. If, for instance, handedness is changed, it has to be noted
that the filter has to be located before the radiator in the air flow. The heater can only be
installed in a certain position because of the security devices. The arrow C on the front
cover of the heater has to point upwards.
An ELECTRIC WIRE, such as MMJ 3x1.5 S D, is connected to the plug in the lower part of
the unit and is led to the outlet E mounted next to the heater.
REMEMBER that preheating requires 16A overheat protection for the power supply of theunit.
The heater has to be installed so as to enable maintenance activities.
USING THE HEATER WITHOUT AN ORIGINAL FILTER IS PROHIBITED.
