2. Functional description
The electronically controlled LogoMatic G2 heat interface stations provide a residential station
with domestic hot water and heating. The domestic water is heated via a stainless-steel plate
heatexchanger and electronic control valves based on the continuous flow principle. The station
must simply be connected to the flow and return lines and the cold water line.
The integrated controller is operated at 230 V / 50 Hz. The mains fuse is 10 A.

Note concerning LM G2 Weather-driven heating circuit control via optional external temperature
sensor (ETS). STM with electrothermal actuator can be ordered as an optional extra. (see chap. 4.3.1)
A dierential pressure regulator in the station allows for hydraulic balancing of the heating circuits.
The zone valve integrated in each device also permits adjustment of the dwelling heating circuit.
Installing a living space or reference room controller (option) allows the independent operation
ofthe dwelling heating circuit.
Adaptors for water meter and heat flow meter (L = 110 mm, 2 x 3/4" MT) are included in the scope
ofsupply of each station.
Note: Additional accessories or options can be found in the current price list (ETS, STM etc.)
Description of the hot water preparation process:
Heating takes place at a preset control value (50 °C; with circulation 60 °C). The control value can
beadjusted as required by the factory customer service team.
If the flow meter identifies a draw-o, the hot water preparation is adjusted to the preset setpoint
value via the control valves.
