The module can only be installed indoors, in a dry and clean place, and the temperature in the room should not
exceed 25ºC or be lower than 15ºC. Operation outside this range reduces the battery life and reduces its capacity. Do
not install the device near heat sources, protect it from fire and sparks.
Supply module installation:
The outdoor temperature sensor T1 should be placed outdoors, away from sunlight, in a way that allows reliable identification of
the ambient temperature (e.g. on an external wall or on the external part of an insulated pipeline).
The water temperature sensor T2 should be placed as close as possible to the heat pump on the outlet pipeline, directly on the
pipe, under the layer of insulation or in a suitable capillary. In the case of pipes made of a material that conducts heat poorly, e.g.
PP-R, it is recommended to find a different location for the sensor, e.g. on a metal fitting, and insulate it effectively. Each of the
sensors wires can be extended to a total length of 15 meters using a 2x0.75mm
2
cable. When wires are leaded together with a
bundle of power cables, it is recomended to use a shielded cable.
1 – pipe, 2 – zipper, 3 – insulation, 4 – water temperature sensor
It is essential to ensure that the sensors T1 and T2 are correctly identified. Incorrect connection of sensors may result
in incorrect operation of the system and lack of antifreeze protection of the heat pump!
Operation and Diagnostics:
Control mode – when the temperature on the external temperature sensor T1 drops below 10ºC, the control mode is activated, in
which the temperature is checked once an hour and the circulation pump is started at the same time. As the outside
temperature drops below 3ºC, the periods of pump downtime are shortened in order to control the temperature of the water
system more reliably.
Antifreeze mode – when the recorded temperature on the T2 water sensor drops below the critical value of 6ºC, the circulation
pump operates according to hysteresis.
Summer mode – the circulation pump is started once a day as part of the function preventing the rotor from blocking.
