The Q60-Heat Distributor separates the engine circuit (Power Unit cooling water circuit) from the heating system via a plate
heat exchanger. The expansion vessel thus protects the engine circuit. The circulation pump for the engine circuit is fitted to the
bottom left of the primary and secondary Q60-Heat Distributor circuits and is equipped with a specially modified connection
on the pump housing for the Q60-Heat Distributor.
Once the Q60-Heat Distributor is connected to the mains, the circulation pumps run for 5-10 seconds to check their proper
functioning.
The pumps do not require any adjustment. They start together with the Power Unit, and stop approx. 5-10 min. after the Power
Unit has shut down. These high-efficiency pumps have a maximum power consumption of 185 W. Their power is controlled
by the Q60-Heat Distributor as required. At maximum power, they circulate up to 6 m³/h.
The system is designed to maximise the storage tank charge temperature (80-85 °C). The storage tank charge group (bottom
right in the Q60-Heat Distributor) controls the engine temperature via the mixer and the speed-controlled circulation pump.
The storage tank discharge group (top right) supplies the heating system with the desired heat.
The Q60-Heat Distributor is equipped with a self-learning control system which monitors the charging and discharging process
and controls the system accordingly.
The charging and discharging of the storage tank enables the Q-Network to:
provide optimum storage tank management
maintain an efficient operation of the boiler and/or heat pumps
pass heat to heating system without any pressure differential
allow the simple setting up of multi-module systems
The Q60-Heat Distributor does not need to be adjusted after installation.
Open the isolation valve upstream of the expansion vessel when filling the engine circuit.
Close the isolation valve between the primary and secondary sides before filling water into the secondary side.
