Recommendations
We recommend the following routine maintenance to assure faultless
unit operation:
1. Do not drain the central heating system after the heating season
2. Get rid of any effluent from the central heating system and boiler
connection points.
3. Leave the controller in stand-by mode and do not cut off power supply
between the heating seasons.
4. Contact with authorised serviceman for an inspection before every
heating season.

Using the boiler
Control panel operation
The control panel consists of two working areas: the signalling area (elements: A-K) and control area (L). The
user can select three operating modes: stand-by, winter (central heating or central h hot water cylinder
heating), summer (cylinder heating).
Stand-by mode
To set the stand-by mode press
. and hold for 2 seconds. Note: Do not cut power supply off between heat-
ing season. When the control panel is switched to „stand-by” mode all indicators are off. In this mode the boiler
is off but the pump is activated every day for 15 minutes (this protects the boiler and the whole central heating
installation from being blocked and silted up). The pump will run every day at the same time, it will be the time
of the day when you switch it to the ”stand-by” mode e.g., if you set the pump on a „stand-by” mode at 6p.m.
the timer will activate the pump everyday for 15 minutes starting at around 6p.m.
Winter mode (central heating or central h hot water cylinder heating)
To set the winter mode (C.H or C.H + H.W.C.H mode) press

mode). The digital display shows the medium temperature. Indicator F flickers when the controller is in the temp.
