Boiler regulation with a room thermostat
.
In this case the boiler is regulated by a room thermostat that is connected to the contacts of the
terminal connector (TP-U1/U2) instead of the interconnection which must be removed. The
boiler in this way also responds to the set up boiler temperature. Instead of a room thermostat,
another device can be used, such as programmable regulator of heating.
Boilers are equipped with an emergency thermostat. In case that the boiler temperature
overcomes 110°C, the boiler is put out of operation safely. Restarting the boiler after water
temperature falls down cannot be done until the reset button is pressed on the control board.
Fuel is filled in the fuel feeder that can be bought as an optional accessory for the boiler. There is
a rule to refuel the feeder before using all the pellet stock in the feeder.
Ash removal must be done in regular intervals. Interval of cleaning depends on the heating
intensity, flue draught and other conditions. During the operation the ash is kept in a replaceable
tin ash collector basin. For cleaning of ash it is necessary to turn the boiler off with the main
switch, clean out the ash collector basin and sweep the boiler bottom. The ash collector is in the
lower part of the boiler behind the cover. For manipulation with the ash collector it is necessary
to use safety gloves to prevent burning. After cleaning the ash collector is returned back and the
cover must be closed properly.
If you need to get the boiler out of operation for a short time, turn the burner switch off and let the
fuel in burner to burn out.
In running out of operation for a long time, firstly turn off the burner switch and let the fuel burn
out. After the boiler cools down below 30°C, you can turn off the main switch and take the
harness connector off the main.
Caution! On the connection contacts of the room temperature is high voltage of 230V!
Before any manipulation with the terminal connector or electrical installation of the boiler
it is necessary to switch the boiler off the mains net!
Caution! The fuel feeder can be open for refueling or cleaning purposes only. During the
operation the feeder must be closed tightly, otherwise there is a danger of fuel ingnition!
