Boiler power output switch
(only for 20, 30, 40, 50 KLO) ("two flames" / "one flame") serves for switching between the two
degrees of power output – full or reduced.
SUMMER/WINTER switch"
SUMMER
("sun" icon) – the boiler cooperates with external DHW reservoir;
WINTER ("snowflake" icon) – the boiler provides heating water and cooperates with external DHW reservoir.
Electric fuse
– protects the boiler's electric installation from overload and short circuits. The fuse must not be repaired or replaced
with "provisional solutions" (wires, etc.). If the fuse has been replaced and after switching the boiler on it was burnt again, a
specialised service centre must be called!
Emergency thermostat
– protects the boiler from overheating
The boiler must not be operated with the safety elements /flue gas and emergency temperature thermostats) disabled
or replaced with elements different from those specified by the manufacturer! Users are not allowed to tamper with
the safety elements.
Heating operation regulator
("radiator" icon) – sets the heating water temperature
l
The set temperature of heating water must be higher than the value set on the pump thermostat – otherwise the pump will be
permanently switched off.
Pump thermostat
– it is a servicing element, set to 0°C in the manufacturing plant. The recommended value is 55°C – a different
value can be set, depending on conditions on site (condensation at low-temperature mode, etc.) – the pump is activated only
when the heating water in the boiler gets to the pre-set value. The settings can only be adjusted by a specialised service centre.
