4. Description of Controls
The controls and indicators are shown in diagrams of the control panels in Figures 3a and 3b below.
There are two control panels – one of them horizontal, under the plastic cover in the top panel, the other is vertical, under the front
panel.
4.1 Horizontal Control Panel
Fig. 3a Horizontal Control Panel
1 - Thermometer
2 – Pressure gauge
3 – Emergency status indicator
4 – Main switch
Thermometer, pressure gauge
– temperature and pressure of the heating water;
Main switch
– switches on/off electric power supply to the boiler;
Emergency status indicator
("Warning Triangle") – when it is on, a "no-flame" defect is indicated – such defects may be caused
by not igniting the flame (no gas), or the chimney draft control system (if there is none or too low a draft) or emergency
thermostat (if the HCW temperature is above 100°C) may have switched the boiler off.
4.2 Vertical Control Panel
RESET
button ("flame" icon)) – to be pressed when a no-flame defect has been indicated (if the boiler was switched off by the
flue-gas thermostat, the button will reset the state only after the boiler has cooled down, in about 10 minutes).
If the defect persists, it is necessary to identify and remedy the chimney draft defect – if the cause is not clear
(suspected clogging of chimney, etc.) a specialised service centre should be called!!!
For defects caused by the emergency temperature thermostat, RESET button will not reset the state and a specialised service
centre must be called to check the boiler and put it back into operation.
