3.1.3 Heating&Cooling Circuits:

This heat pump unit can control two totally different heating/cooling circuit, as shown in the drawing.

Temperature setting can be made via menu “Heating & Cooling Circuit 1” and “Heating & Cooling Circuit 2”.

Of course, if only one circuit is needed, “heating&cooling circuit 2” in system drawing can be omit, and leave
the “Heating&cooling Circuit 2” under “heating&cooling circuit 2” set to OFF:

3.1.4 Heating & Cooling Circuit 1

Control of Mixing Valve 1(MV1):

If system water temperature may higher(lower) than temperature that are need for circuit 1 in heating (cooling)
operation, then a mixing valve can be add to circuit 1, and connected to MV1 port in indoor unit.

Unit will control the mixing valve, mix the supply and return water of circuit 1 to have the temperature read via
sensor TV1 get to value set under menu “Heating & Cooling Settings circuit1”.

If so, TV1 under menu ““Heating & Cooling circuit1” should be activated under installer’s level:
