If the temperature of the heating water decreases below 8°C, the circulation pump for heating is activated and
the boiler heats up. The heating is disconnected when the temperature of the heating water exceeds 20°C. If the
output restricted to 0 is enabled, the boiler does not respect this restriction and heats with one heating body.
Automatic setting of restriction of output without signal
For the simplification of the commissioning of the boiler (without the necessity to take care of the use of signal
HDO) the following algorithm is programmed in the automated system:
- the initial value of restriction without the signal HDO (P4.4) = maximum output of the boiler (factory setting),
- after first activation of the automatic system and always after returning to the factory setting, the circuit
breaker is activated which enables to make one automatic change to parameter P4.4,
- this circuit breaker is deactivated:
1) either by the change/confirmation of parameter P4.4 by the setting in the menu (after confirm. by button 4),
2) or by automatically changing parameter P4.4 according to the following point.
- after the first supply of active signal HDO for a period of at least ten seconds (non-stop) parameter P4.4 is
rewritten to the zero value. Parameter P4.4 is rewritten only in the case that the circuit breaker is activated; after
rewriting the circuit breaker is deactivated.
Priority control of the boiler of regulator OT/+
If regulator OT/+ is connected to the automation system, its commands take priority against the adjusted regime
of heating. The exception is if the adjusted regime is disconnected. The adjusted heating regime is applied during
the failure of the regulator or in the case that the regulator is not connected. In the following table is the summary
of the heating regimes in individual situations.

1) Home screen and display saver – the whole area of the display. Transfer to basic display.
2) Basic display – on the up in the middle of the display. Change of manner of display –high/damped backlit,
option blue on white or white on blue.
3) Info screen – on the up in the middle of the display. Transfer to the display of service information (firmware,
lower sensor of temperature in the storage tank of DHW, optical inputs, etc.)
4) Info screen – on the up in the middle of the display. If failure 10 is signalled – error in communication in the
cascade, there is switching to the detailed description of the error – list of slave boilers which do not communicate.
5) Screen with service information – the whole area of the display. Return to info display
6) Screen with menu – slightly above the centre (height) on the right edge of the display, approximately on the
typed value.
Further options:
- during the display of menu item LANGUAGE prolongation of the basic menu to service menu,
- during the display of menu item ERROR HISTORY, value 20 – DELETE deletion of error history,
- during the display of menu item TYPE OF BOILER returning to the factory setting for the service menu items,
