Premium
Version D0000095883-c 10.01.2022
The brine-to-water heat pump is equipped with an integrated "WPM" heat pump manager and a
control panel in the top panel of the unit.
The speed-controlled rotary piston compressor is controlled by an inverter. The heat output is adjusted
depending on the power. The circulation pumps for the heat source and heat extraction are built into the
unit. These are controlled via a PWM signal. The multi-function module "MFG" has a change-over valve
and controls the operating modes heating and hot water. Two integrated expansion vessels of 24l each
for the brine and heating circuits are located in the unit.
Refrigerant R 454 C safety class A2L (low flammability) is used in the refrigerant circuit.
The "cool" version offers the additional option of passive cooling (without a cooling circuit) by means of
an additional plate heat exchanger. This enables the temperature exchange between the heating system
and the heat source by means of a switching valve.

Page 39: Noise When Bypassing The Change-Over Valve
Repair instructions HPG-I 04-06-08-12-15 S-CS-DS-DCS Premium In cooling mode, incorrect circulation at the changeover valve (MA12) can cause the DHW storage tank to cool down, the system frequently interrupts cooling mode and recharges the DHW storage tank. Insufficient cooling and higher energy costs are the result. Check the function of the multifunction group. 15.3.4 Noises when bypassing the change-over valve If there is no PWM signal at the internal circulation pump, the pump runs constantly at 100%, the automatic speed reduction before switching over is ineffective. -
