Cool Mode:
B = 0 ; when Zone OFF or Zone Room Thermo OFF
B = B = 1* (room set temp (R/C) – actual room temp)
Max/Min Regulation of B: (Max = 5 ; Min = -5)
Heat Mode:
B = 0 ; when Zone OFF or Zone Room Thermo OFF
B = follow Heating Room Temperature PI control logic

* Between outdoor ambient -10°C and -15°C, the water outlet temperature gradually decreases from 60°C to 55°C
Compensation Type: (Operation under Heat Mode and Cool Mode)
The set temperature defines the parameters for the ambient (Outdoor temperature) dependent operation of the
unit. The water temperature is determined automatically depending on the outdoor temperature. Default setting is
the colder outdoor temperature will result in warmer water and vice versa. The user has the possibility to shift up
and shift down the target water by remote control setting.

However, when powerful mode is requested by remote control during heating mode, the higher value of HLo or Whi
will be used for A calculation.
* There are 2 compensation curves (for heating and cooling). During heating mode, the heating curve is used and
during cooling mode, the cooling curve is use.
