UEL CONTAINER PROTECTION
On the fuel feeder there is an additional temperature measuring sensor. In the event of its signif-
icant increase (above 70
causes pushing the fuel to the combustion chamber. This way the feeder sensor protects against fuel
ignition in the container.
The regulator has a WT 6.3A tubular fuse insert, protecting the network. Using a fuse with a higher
value can cause damage to the existing controller

AINTENANCE
Technical condition of wires should be checked in the ST-48 controller before the heating season
starts and across its duration. One should also check fastening of the controller and clean it from dust
and other dirt. The earthing effectiveness of the engines ( of the CH pump, the HUW pump, the blow-in,
the feeder, the floor pump, the circulation pump)should also be measured.
