In this function, you can switch on or off the stand-by mode for the
thermoregulator. All motors of devices (e.g. fan) that are connected to
the thermoregulator are stopped.
ATTENTION: in the stand-by mode, the power is not cut off
completely.
Alternatively, you can switch the controller into the stand-by mode by
pressing and holding the encoder for several seconds.
VI.Protections
In order to ensure a safe and faultless operation, the regulator has
been provided with numerous protections. In the case of an alarm, an
acoustic warning is sounded and the display shows an appropriate
message.
Press the encoder to restore the controller to operation.
VI.1.Temperature Alarm
The protection is enabled only in the duty mode (i.e. when the
furnace temperature is lower than the setpoint temperature ). When the
furnace temperature fails to rise in the user-defined period, an alarm is
activated: the feeder and the fan are shut off (the water pump is
activated regardless of the furnace temperature) and the alarm is
sounded. The display shows an appropriate message:
If you press the encoder , the regulator will deactivate the alarm.
The regulator will return to the previous working mode.
VI.2.Thermal Protection
The boiler is protected with an additional bimetal sensor (located at
the furnace sensor) that deactivates fan and feeder outputs when the
