Description: The pump (9) starts after exceeding the pump starting temperature. The boiler (1) will switch off after
loading the buffer tank (13). The boiler (1) have to be equipped with security measure against cold water returning to
the boiler e.g. thermostatic 3-way valve. The pump (2) starts together with the boiler (1) and turns off after turning off
the boiler (1), but with 5 min. time delay.
