There is a boiler controller to which a number of external appliances can be connected
and the controller working modes can be set. Additionally, it signals some modes that
help to the initial start up and checking correct operation of the boiler.
1. A room thermostat should be connected to the boiler through the RT [3] entries.
When the connections are opened, the boiler will recognise that the required
temperature in the room is reached. In this case the boiler will switch the heating
off. LED [5] on the controller board signalises the room thermostat status. The
[5] LED indicator illuminates when the thermostat connections are closed.
2. Pump. Use the [4] entries to connect a pump. The pump is powered by the fuse
(1A delayed 230V) that is situated on the controller board with the use of con-
nector. When the pump is running, the LED indicator [6] is also is illuminated.
3. Choosing the pump mode. There are set up switches on the control board to
control the operating mode of the pump. Setting the switch to „ON” position chang-
ing the pump mode to constant work, despite the status of the room temperature
connected to RT entry [3]. If the set up switch is in different position, the pump will
operate in an automatic mode (i.e when the room temperature reaches the set
limit of the room thermostat, the pump will be turned off – RT connection closed).
