Tech Controllers EU-ML-12 User Manual page 28

→ Always OFF - the pump is switched off permanently and the controller only controls the operation
of the valve
→ Turned ON above the threshold - the pump turns on above the set switching temperature. If the
pump is to be switched on above the threshold, the threshold pump switching temperature must
also be set. The value from the CH sensor is taken into account.
•
Switch-ON temperature - This option applies to the pump operating above the threshold. The valve pump
will switch on when the boiler sensor reaches the pump switching temperature.
•
Pump anti-stop - When enabled, the valve pump will turn on every 10 days for 2 minutes. This prevents
water from fouling the installation outside the heating season.
•
Closing below temperature threshold - When this function is activated (check the ON option), the valve
will remain closed until the boiler sensor reaches the pump switching temperature.
CAUTION
If the additional valve module is an i-1 model, the anti-stop functions of the pumps and the closure
below the threshold can be set directly from the sub-menu of that module.
•
Room controller pump valve - Option whereby the room controller switches the pump off once heated.
•
Pump Only - When enabled, the controller controls only the pump and the valve is not controlled.
➢ External sensor calibration – This function is used to adjust the external sensor. This is done during installation or
after prolonged use of the sensor if the displayed external temperature deviates from the actual. The user specifies
the correction value applied (adjustment range: ‐10 to +10°C).
➢ Closing – Parameter in which the behaviour of the valve in the CH mode is set after it is switched off. Enabling this
option closes the valve, while disabling opens it.
➢ Valve Weekly – The weekly function allows users to program deviations of the valve set temperature on particular
days of the week at specific times. The temperature deviations set are in the range of +/-10°C.
To enable weekly control, select and check
following sections of the submenu:
PLEASE NOTE
For the correct operation of this function, it is necessary to set the current date and time.
MODE 1 - in this mode it is possible to program deviations of the set temperature for each day of the week
separately. To do this:
→ Select the option:
→ Select the day of the week for which you wish to change the temperature settings
→ Use the
confirm the selection by pressing the MENU button.
→ Options appear at the bottom, select CHANGE by pressing the MENU button when it is highlighted in
white.
→ Then decrease or increase the temperature by the selected value and confirm.
→ If you want to apply the same change also to the neighboring hours, press the MENU button on the
selected setting, and after the option appears at the bottom of the screen, select COPY, then copy the
setting to the subsequent or previous hour using the
pressing MENU.
