is
measured incorrectly.
Check if there is good thermal contact between the temperature
sensor and the measured surface,
Whether the sensor lead is not placed too close to the mains
cable,
If the sensor is connected to the terminal,
Whether the sensor is not damaged – check it in accordance with

The
boiler
overheats
despite disabled airflow.
The reason can be faulty chimney installation (no protection
against excessive chimney draught).
In a hydraulic system with
a mixing valve and servo -
the mixer fails to open.
The reason may be activity of the return protection function. If
the return protection function is active, check if the sensor for
water returning to the boiler is thermally insulated from its
surroundings, and improve contact with the pipe by applying
thermally conductive paste. Increase the pre-set boiler
temperature in order to provide power reserve needed to heat
the return water. Check if the hydraulic system is properly
made, i.e. after closing the valve, the return temperature must
be able to exceed the parameter

The reason can be active SUMMER function.
The reason can be an on-going calibration of the mixer valve,
wait until the calibration is complete. Active calibration is
signalled with a “CAL” message in the menu INFORMATION –

Regulator setup by boiler manufacturer.
CAUTION: THE INDIVIDUAL FUZZY LOGIC PROGRAM IS SELECTED
INDIVIDUALLY TO THE GIVEN BOILER TYPE. MAKE SURE THAT THE FITTINGS
FOR BOILERS TESTED IN THE PLUM LABORATORIES ARE COMPATIBLE WITH
FITTINGS FOR SOLD BOILERS. IT IS INADMISSIBLE TO REPLACE THE FEEDER
AND FAN TO OTHER TYPES AS WELL AS MAKING OTHER CONSTRUCTIONAL
MODIFICATIONS WHICH CAN HAVE IMPACT ON COMBUSTION PROCESS.
23.1
Activating Individual Fuzzy Logic and changing boiler type
In order to activate the Individual Fuzzy Logic mode, enter MENU:
MENU > Regulation mode
In
this menu, find and confirm Individual Fuzzy Logic mode
If the boiler operation modes list is unavailable, and clicking the aforementioned menu
triggers a message “Function unavailable”, it means that the regulator operates only in
the STANDARD mode, Individual Fuzzy Logic control is disabled and unavailable for the
given setup of a boiler.
