3 About the product
The HPM heats up the water by the principle of repeatable circulations to reach set point tem-
perature, typically, 5-15 passes to fully heat op a water tank starting with cold water.
Therefore the following should be observed during installation:
- The hot water inlet from the heat pump shall be placed, e.g., 1/3 down from the top to ensure
that hot water is available for use while the heat pumpe heats up the lower 2/3 of the water
tank.
- The heat pump control sensor, T8, shall be located around the how water inlet from the heat
pump. If a higher readyness of hot water is required the sensor location can be lowered.
- Sensor T7 can be used for optional display of temperature in the top of the tank.
- If an optional electrical heater is controlled by the HPM sensor T7 shall be installed ABOVE the
electrical heating element sensor sensor T7 is controling sensor for the electrical heater. It is
recommended to use a safety breaker which will disengage at 80°C.
- A fixed speed pump shall be installed on the cold water return to the HPM. A pump rate
between 200-600 l/h is advisable. Higher pump rates gives better HPM performance but also
consumes more circulation pump power.
