The controller and the above mentioned peripheral devices have been matched to
the application covered by this data sheet. Therefore, valve and sensors may not
be replaced by products of other manufacture.
Safety transformer (25 VA) to EN 60 742 is not included in the delivery.
Configurable functions
The controller's functions are preconfigured. By changing the parameters, the func-
tions can be matched to the type of plant.
Control of the evaporator is based on true superheat control. For this purpose,
pressure P0 acquired at the evaporator output is converted to the respective tem-
perature of the refrigerant used.
The controller contains the polynomials of the following types of refrigerants:
