Tehnical caracteristic 

The construction of the heat pump unit allows installation indoors; the unit housing is made of 

sheet metal, incorporating an operating panel used for adjustment of the required parameters by 

the user. The control unit, located under the upper part of the unit, is used for connection to the 

electricity supply and for connection of the circulating pump, temperature probes and mixing 

valves. 

The unit cooling circuit is filled with 

R407C

 refrigerant. This type of refrigerant is non-combustible 

and does not contain ozone-depleting substances.
