ST – 480
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).
