deactivate its operation in the driver of valve ST-431.
IV.d) Temperature control
This parameter determines water temperature measurement (control)
frequency behind the CH or HWT installation valve. If the sensor indicates a
change in temperature (deviation from the set value), then the electric valve
will open or close by the set stroke, in order to return to the preset
temperature.
IV.e) Reduction in room control
This function is active only in the case when the valve cooperates with
the room regulator. In this setting, one should preset the temperature by
which the valve decreases its preset temperature, at the moment of achieving
the preset temperature at the room regulator (room heat-up).
NOTE: If in function Room regulator (see IV.e) option Closing is set, then
function Reduction in room control is inactive.
IV.f) Room regulator
This option is used to set the manner in which the valve will react to a
signal about room heat-up (from the room regulator). If option Reduction in
room control is selected, then the valve, after a signal about heating-up (from
the regulator room) will lower temperature behind the valve – according to
the set parameter
Reduction in room control (see IV.e). In the event when
option Closing is selected, the valve will react to the signal about heat-up
room with maximum closing (see item IV.m) and deactivation of the pump.
IV.g) Proportionality coefficient
