14 HEAT REGULATION SYSTEM FOR RETURN FLOW
14.1.1 Application example
Example of use
Boiler/heat source
14.1.2 Setting the reflux temperature
The temperature setting range lies between 40 °C and
65 °C. The desired temperature of the regulated heating
circuit can be set at the top of the component’s
thermostat and can be read from the thermometer in
the return (blue).
Note:
The temperature in the regulated heating circuit is
not immediately set after altering the top of the thermostat
meaning that the temperature can be read
after an appropriate operating time of the regulated
heating circuit.
14.2 Return line raising MK DN 5 (1“) /
electronically controlled
The function corresponse to the thermostatic type
(page 26). The difference is the 3-way T-mixer and
3-point actuator (230 V AC/50 Hz), including return
temperature regulation (adjustment range 20 °C to
80 °C).
