Room controller function - In this function, it is necessary to set whether the valve will close (Closing) or
the temperature will lower
➢ Proportionality coefficient – The proportionality coefficient is used to determine the valve stroke. The closer to the
set temperature, the smaller the stroke. If this coefficient is high, the valve will reach a similar opening faster, but it
will be less precise.
The percentage of the unit opening is calculated using the following formula:
➢ Maximum floor temperature– This function specifies the maximum temperature that the valve sensor can reach (if
Floor valve is selected). When this value is reached, the valve closes, switches off the pump and the information
about overheating of the floor appears on the main screen of the controller.
CAUTION
This parameter is only visible if the valve type is set to
➢ Opening direction – If, after connecting the valve to the controller, it turns out that it was supposed to be connected
in the opposite direction, it is not necessary to switch the supply lines - as it is possible to change the opening
direction of the valve by selecting the selected direction: Right or Left.
➢ Sensor Selection – This option applies to the return sensor and the external sensor and allows determining whether
the additional valve operation should take into account the
main controller (Only in Slave Mode).
➢ CH sensor selection – This option applies to the CH sensor and allows determining whether the function of the
additional valve should take into account the
in slave mode).
➢ Boiler protection – Protection against excessive CH temperature is intended to prevent dangerous increase of boiler
temperature. The user sets the maximum permissible boiler temperature. In the event of a dangerous temperature
rise, the valve begins to open to cool the boiler down. The user also sets the maximum permissible CH temperature,
after which the valve will open.
CAUTION
The function is not active for the
➢ Return protection – This function allows setting the boiler protection against too cold water returning from the main
circuit (which could cause low temperature corrosion of the boiler). The return protection works in such a way that
when the temperature is too low, the valve closes until the shortened circuit of the boiler reaches the required
temperature.
CAUTION
The function does not appear for the valve type Cooling.
