ON – When the temperature of the heat source is lower than the Min. temperature for
the circuit, the controller lowers the circuit preset temperature, but only when there is
no active reduction from the operation mode.
OFF – the regulator does not reduce the circuit preset temperature.
Temperature value at which heat excess is discharged to the heating circuit. It is protection
against overheating.
Turns off heat source when the starting thermostat contact.
Increase of the heat source preset temperature above the heating circuit preset temperature.
Turns on or off support of the return temperature sensor. Enabling the sensor support shows
additional parameters related with the function of protecting the boiler return from cold water.
It is realized through a mixing valve with an electric actuator. Note: Do not turn sensor support
if there is no electric actuator mounted on the valve! This function is not available when the
return sensor is not connected or its support is disabled. Function activation results in valve
closing.
The temperature below which the electric actuator turn a blind mixing valve.
Electric actuator will return to normal working at return temperature ≥ Min. temperature +
Hysteresis.
It is % opening to the mixing valve during active the return protection function. Note: The
valve closes with an accuracy of +-1%.
ON or OFF frost protection function.
Time delay for enable frost protection function. Description later in this manual.
The temperature below which the frost protection function is activated . Description later in
this manual.
ON or OFF supporting the room thermostat (NO-NC).
Additional correction of the errors for the temperature sensor: T1 - heating circuit, T2 –
external, T3 – return, T4 - boiler.
Enable support external temperature sensor (weather) for controlling the heating circuit. In
the event of external sensor damage on the screen displays the message " Damage sensor
external temperature ". Enabling support cause additional parameters in the menu to the
weather control.
Manually turn ON or OFF working CH pump, mixer actuator, contact the heat source in order
to control the correctness of their actions.
Note: The long time activation of the pump - can be damaged this pump.
Activating or Deactivating the screed floor drying function (heating by floor circuit). Schedule
of temperature changes in time is shown on the screen in the form of graphs appropriate for
programs P1..P7. Select the correct program for the used type of screed and environmental
conditions.
Drying is performed by a corresponding change in floor circuit temperature in the range
10..50ºC in a time of 30 days. Drying can be deactivating at any time. Re-activation function
makes that the drying works all over again for 30 days.
Restore defaults settings
Selecting YES will reload all the factory settings.
