4.13. OPENING DIRECTION
If, after connecting the valve to the controller, it turns out that it is connected the other way round, then the power supply
cables do not have to be switched. Instead, it is enough to change the opening direction in this parameter: LEFT or RIGHT.
4.14. RETURN PROTECTION
This function enables the user to set boiler protection against too cool water returning from the main circulation, which could
cause low-temperature boiler corrosion. The return protection involves closing the valve when the temperature is too low,
until the short circulation of the boiler reaches an appropriate temperature level. Once it is activated, the user presets the
minimum acceptable return temperature.
4.15. VALVE PUMP
Pump operation modes
This option is used to select the pump operation mode.
o Always ON - the pump operates all the time, regardless of temperatures.
o Always OFF - the pump is permanently deactivated and the regulator controls only valve operation
o ON above threshold - the pump is activated above the pre-set activation temperature. If the pump is to be
activated above the threshold, the user should also define the threshold temperature of pump activation. The
temperature is read from CH sensor.
o Deactivation threshold*- the pump is enabled below the pre-set deactivation temperature measured on
CH sensor. Above the pre-set value the pump is disabled.
*Deactivation threshold function is available after selecting Cooling as the valve type.
Pump switch on temperaturę
This option concerns the pump operating above the threshold (see: above). The valve pump is switched on when the
CH boiler reaches the pump activation temperature.
Pump anti-stop
When this function is active, the valve pump is activated every 10 days for 2 minutes. It prevents stagnant water in the
heating system outside the heating season.
Closing below temp. threshold
Once this function is activated (by selecting ON), the valve remains closed until the CH boiler sensor reaches the pump
activation temperature.
Valve pump room regulator
When this option is active, the room regulator disables the pump when the pre-set temperature has been reached.
Only pump
When this option is active, the regulator controls only the pump while the valve is not controlled.
4.16. VALVE REMOVAL
This option is used to remove the valve from the controller memory. Valve removal is used e.g. at disassembling the valve or
module replacement (re-registration of a new module is necessary).
