Faster reaching the readiness of CWU accumulator by limiting heat obtain by heating
system. The pump CO works cyclically. Turning off the pump CWU after supplying the accumulator
causes the comeback of normal operation of the pump CO
beyond time zones the pump operates like in the ZA
Ł
mode and in time zone like PRIO

„
CONTROL
”
The regulator is equipped with the relay CONTROL whose contacts can be used e.g. to switch
off another heat source when a fireplace works. The
“
PrzekSTR
”
parameter defines the function of
the relay more precisely
3 Service of the regulator
There are elements on the control panel (fig. 2).
The state is presented on the text display (1). The screens inform about the operation of devices,
temperature of sensors; they make it possible to change the parameters etc..The change of screen is
done by pressing the WYBIERZ button (3). If this is the screen that is able to change a parameter,
press the USTAW button, which causes blinking of the parameter field to be changed. By pressing
“
+
”
(2) or
“
-
”
(4) one can alter its value.
If there are more parameter fields on the screen (e.g. setting the clock) then one will go among them
by pressing the WYBIERZ button (3).

By clicking the USTAW button (5) one confirms the changes - the parameter field stops blinking.
The changed parameter not confirmed for 10 secs is not accepted by the regulator and it recalls a
previous value of the parameter.
