CTC GSi 600 

DHW connections

The property’s DHW 
connections are connected 
here.

Radiator connections

The property’s heating 
system is connected here.

DHW heat exchanger

The heat pump is equipped 
with a stainless steel heat 
exchanger.
Direct heating of hot water 
minimises the risk of 
legionella bacteria.

Flow heater

There is an electric heater for 
additional heating here.

3-way valve

Flow conditioner.

Terminal block for sensors

The sensor terminal block 
is wired internally. Outdoor 
sensors, room sensors and 
other sensors are connected 
easily here.

Junction box (A5) 
Module

Max. thermostat 
(F10)

Charge pump (G11)

Pump for the hot side 
(concealed, placed behind 
the electrical connection 
box).

Brine pump (G20)

Circuit breakers (F2)

Circuit breakers (F1)

Junction box 
(A2)

Brine connections

The brine is connected to 
the collector here.

2.  Design

The picture below shows the fundamental construction of the heat pump. 

The energy in the bore hole (bedrock) or ground is drawn up by the cooling system. 

The compressor then increases the temperature to a usable level. Afterwards it releases 

the energy for the heating circuit and DHW.

Circulation pump, DHW

Charge pump (G5) for 
DHW out temp.
