III.d Main valve

III.a.1 Switch on

This feature allows you to temporarily make the valve inactive.

III.a.2) Set-point valve temperature

This setting is used to set the circuit temperature to be maintained by the mixing valve. This is
the main temperature based on which the room thermostat reduction function is to be run (see
Section III.a.10). The room thermostat reduction function is set separately for the CH system
(setting in the user menu) and separately for each of the valves.

III.a.3) Temperature control

This parameter determines the sampling (control) frequency of the water temperature
downstream of the valve for the central heating or hot water system. If the sensor indicates a
change in temperature (deviation from set-point), then the solenoid will open or close partially
by a preset step to restore the set-point temperature.

III.a.4) Opening time

You can use this function to set the time for the full opening of the valve, that is to say, how
long it takes to open the valve to 100%. This time should be selected according to your valve
actuator (shown on the nameplate).
