Time constant of adaptation – the parameter is available when the thermostat is in
the mode of adaptation. It defines the rate of „searching' the appropriate boiler
programmed temperature by the algorithm of adaptation. The value of parameter
should be selected experimentally depending on the properties of the heated object.
When frequent room overheating occurs during the work of the algorithm of
adaptation and frequent changes in the outside conditions – the value of the time
constant should be decreased.

Delay in burner switch off – the parameter determines the working time of the
burner at the minimum power and when the thermostat contacts are opened. Once
the programmed time is finished and the thermostat contacts are not closed again,
the burner will be extinguished and the controller will enter the STANDBY mode.
When the parameter is set to the „0min” value, the burner will be extinguished
immediately after the thermostat contacts have been opened.

CAUTION! The burner may be turned off after the thermostat contacts have been
opened with a delay different from the programmed one if the DHW circulation is
also controlled.
5.9. Service settings.
If „YES” selection followed and was confirmed with OK button when this option is
displayed will result in cancelling of all parameters and restoration of default
parameters programmed before by the fitter or technician.

CAUTION! Activation of this function will result in restoration of service parameters
for current fuel type only.
5.10. Output testing.
It is possible to test particular preset functions. This is available, only, if the controller
is in STOP mode before switching to service mode. To select outputs testing option
use the knob (12) choosing particular outputs which are indicated by flashing of the
proper light and output name displayed. By pressing OK button you can turn on the
selected output temporarily. To finish output testing press STOP button.
