INFORMATION

A pressure regulating valve should be implemented before the mixing valve station.
This is to guarantee the correct water flow balance between the main leaving water
temperature zone and the additional leaving water temperature zone in relation to
the required capacity of both water temperature zones.

▪

For  the  main  zone:  the  room  temperature  is  controlled  by  the  user  interface,
which is used as room thermostat (optional equipment EKRUDAS).

▪

For the additional zone:

-

The external thermostat is directly connected to the indoor unit.

-

The  desired  room  temperature  is  set  via  the  external  thermostat  and  the
thermostatic valves of the radiators in each room.

-

The  heating  demand  signal  from  the  external  thermostat  is  connected  to  the
digital  input  on  the  indoor  unit  (X2M/35a  and  X2M/30).  The  indoor  unit  will
only supply the desired additional leaving water temperature when there is an
actual demand.

▪

The  user  interface  integrated  in  the  indoor  unit  decides  the  space  operation
mode.  Mind  that  the  operation  mode  on  each  remote  controller  of  the
heat pump convectors must be set to match the indoor unit.
