parameter. To make a selection, use the (+, -) buttons. In order to confirm new settings
you should use the OK button; then the regulator enables the user to select the next
parameter. Pressing the (*) button during edition will cancel the introduced change.
Exiting the default settings follows automatically 60 seconds after the recent use of the
button or selecting and confirming [End] option.
CAUTION!
If the regulator is in the service mode, the work of control devices is
stopped until the time of exiting the mode.
In table 1 the list of all available parameters has been presented. The first column
contains examples of display unit indications, the next columns – description of
a parameter, the minimum and maximum values possible to set, as well as a change
of the value while setting; the values preprogrammed by the producer are included in
the last column. One may return to the values by selecting the [Prod] option.

4.1 Module operating mode and type of the temperature sensor.
Depending on the setting of the service parameter [to 1] the module can work in one of
the two modes.
The
[to 0]
mode means that the module controls the mixing valve maintaining
a constant, preset by the user, temperature of the heating circuit. In this mode, the
outside temperature sensor input may be left unconnected.
The
[to 1]
mode indicates that the module is working in a weather-based mode, which
means that the water temperature in the heating circuit depends on the outdoor
temperature. In this mode it is necessary to connect the outdoor temperature sensor.
