MIXING VALVE
The EU-L-X WiFi controller can operate an additional valve using a valve module (e.g. i-1m). This valve has RS communication,
but it is necessary to carry out the registration process, which will require you to quote the module number located in the
rear of its housing, or in the software information screen). After correct registration, it is possible to set individual parameters
of the Additional valve.
➢
Information
- the function allows you to view the valve parameters status.
➢
Register
- After entering the code on the back of the valve or in the
Menu →
Software Information
, you can register
the valve with the main controller.
➢
Manual mode
–
the user has the ability to manually stop the valve operation, open/close the valve and switch the
pump on and off in order to control the correct operation of the devices.
➢
Version
- This function displays the valve software version number. This information is necessary when contacting
the service.
➢
Valve removal
- This function is used to completely delete the valve. The function is used, for example, when
removing the valve or replacing the module (it is then necessary to re-register the new module).
➢
On
–
option to enable or disable the valve temporarily.
➢
Valve set temperature
–
this parameter allows you to set the valve set temperature.
➢
Summer mode
–
turning on the summer mode closes the valve to avoid unnecessary heating of the house. If the
boiler temperature is too high (enabled boiler protection is required), the valve will be opened in emergency mode.
This mode is not active in
Return protection
mode.
➢
Calibration
- This function can be used to calibrate the built-in valve, e.g. after prolonged use. During calibration,
the valve is set to a safe position, i.e. for the CH valve and the
Return protection
type
to reach its fully open position,
and for floor valve and the
Cooling
type, to fully return to its closed position.
➢
Single stroke
- This is the maximum single stroke (opening or closing) that the valve can perform during single
temperature sampling. If the temperature is close to the set point, this stroke is calculated on the basis of the
Proportionality coefficient
parameter. The smaller the unit stroke, the more precisely the set temperature can be
reached, but the set temperature is reached over a longer period of time.
➢
Minimum opening
- A parameter that specifies the smallest valve opening in percent. This parameter enables the
valve to be left slightly open to maintain the minimum flow.
CAUTION
If we set the minimum opening of the valve to 0% (complete closing), the pump will not operate when the valve
is closed.
➢
Opening time
- A parameter that specifies the time it takes the valve actuator to open the valve from 0% to 100%.
This time should be selected to match that of the valve actuator (as indicated on its nameplate).
➢
Measurement pause
- This parameter determines the frequency of measuring (control) of water temperature
downstream of the CH installation valve. If the sensor indicates a temperature change (deviation from the set point),
then the solenoid valve will open or close by the preset value to return to the preset temperature.
➢
Valve Hysteresis
- This option is used to set the valve setpoint temperature hysteresis. This is the difference
between the preset temperature and the temperature at which the valve will start to close or open.
