Inspection and preparation of the heating system and its controll unit for upcoming heating season

OPERATIONAL TEST OF THE CONTROLLERS

Room Thermostat

OPERATIONAL TEST OF THE ROOM THERMOSTATS

  • The test of the room thermostats is carried out with the increasing of the desired temperature or activation of the PARTY function. After we activated it, we wait that the system starts to heat.  If this isn't the case, we check if the boiler is turned on, if the safety thermostat on the boiler was activated and if the burner on the boiler is working.
  • Also check the wire connections to the boiler, pumps and actuators.
  • Battery check - if the battery is discharged more than 70 %, you should replace it.

OPERATION TEST OF WEATHER COMPENSATED HEATING CONTROLLERS

  • Check whether the controller isn't showing any notices or errors. If the controller doesn't allows this, check if the measured temperatures are correct and if all temperatures from the connected sensors are displayed/shown.
  • If the controller possesses stored records (logs) concerning notices and malfunctions while operating, review the records, to detect possible borderline cases or malfunctions.
  • Check if the controller in the summer time automatically activated the pumps and actuators. If not, you should manually turn on the device and check if its work properly. If necessary, manually rotate the circulation pump and the actuator. Newer controllers know the »manual« operation function, where every control output can be activated manual.
  • If the controller has a built-alkaline battery to power the clock, replaced it every two years.

TEST OF THE SAFETY THERMOSTATS (STB) BY BOILER CONTROLLERS KXD, KUD, KPD IN WXD

  • Controllers are equipped with a special button »Chimney Sweep«, which allows you to start the test process of the safety thermostats »STB«. You proceed as described in the instructions for certain controller. The »STB« test function turns on the heat source and allows to heat water to the extent, so the safety thermostat »STB« switches on. After the test procedure completion, and when the boiler is cooled down to it working temperature we turn off the »STB«.
  • If the controller has a built-alkaline battery to power the clock, replaced it every two years.

MEASUREMENT OF EMISSIONS OF FLUE GASES BY COMBUSTION PLANT WITH CONTROLLERS WDC, KXD, KUD, KPD IN WXD

  • By controllers WDC, WXD, KXD, KUD and KPD a »Chimney Sweep« feature is built in, which allows measurement of emissions of flue gases. The controller switch on the boiler or burner and 20 minutes maintains the operating/working temperature of the boiler. In-between this period the service man or chimney sweeper can implement the emission measurement.

How to activate the »Chimney Sweep« function:
