Malfunctions and the display codes of the boiler
At the beginning of the day, the installation is heated up
too far, too long.The rooms become too warm.
1. Lower the temperature in the clock program, for the
switching point of the beginning of the day.
2. Raise the PID setting, so that the installation will burn less
intensely.
3. If the capacity of the boiler is much higher then necessary, the
water will be heated up too fast. By means of the partial load
potentiometer on the UBA, the maximum capacity for heating
up the water can be reduced, so that the water will be heated
up more slowly.
4. If the rooms have been equipped with too many or too large
radiators, the house can also be heated with water of a lower
temperature.The maximum temperature setting of the water
can be reduced on the UBA.
The room becomes too warm (warmer then the set
temperature).
1. Is the IRT 30 thermostat able to measure the correct
temperature (only for RR and WD + RTC)? Is the IRT 30
thermostat installed on a cold outside wall or in stream of
draught?
2. If the rooms have been equipped with too many or too large
radiators, the house can also be heated with water of a lower
temperature.The maximum temperature setting of the water
can be reduced on the UBA.
3. Are the thermostatic radiator valves installed correctly?
(Is cold air streaming around the thermostatic radiator valves)?
It is too cold (colder then the set temperature) in the
room.
1. Is the IRT 30 thermostat able to measure the correct
temperature (only for RR and WD + RTC)? Is the IRT 30
thermostat installed between cupboards (no natural airflow)
or in the vicinity of heat sources (tv, refrigerator, radiator,
etc.)?
2. Are the thermostatic radiator valves completely open in the
room where the thermostat has been installed?
3. Check the setting of the maximum CH water temperature on
the UBA (90 °C maximum).
4. Has the pump switch on the UBA been set to position 2 (only
for WD and WD + RTC)?
