[H4]
Example
:
When setting hysteresis value of, e.g. H4 in the CO mode and
temperature of e.g. 40 °C, the pump will be switched on when
the temperature exceeds 42 °C and will be switched off when
the temperature drops to 38 °C.
When this information is displayed, you can change the set value by
pressing the (
–
) or (
+
) button. The range of hysteresis values that can be
set for the controller is
from 2°C to 8°C
(
to
). After the change is
[H2]
[H8]
made, it is stored automatically.
The hysteresis can be changed by simultaneously pressing and holding
both the (
–
) and the (
+
) button for 4 seconds.
When setting hysteresis value of, e.g. H4 in the CU mode and
temperature of e.g. 40 °C, the pump will be switched off when
the temperature exceeds 42 °C and will be switched on when
Setting of the hysteresis
To do so, press and hold the right button (

) for 2 seconds. Use of this
functionality is indicated by illumination of the right red indicator light
and the

The controller makes it possible to manually switch on and off
the CH or
DHW pump.
NOTE:
In the
mode of operation, the pump will be on until the
[CU]
temperature reaches 90 °C. Once this value is reached, the pump
will switch off. After the temperature drops below 90°C,
the pump is switched on again.
The pump continues to work regardless of the temperature set on the
controller and the actual temperature in the location of the sensor.
In order to switch the pump off, press and hold the right button (+2)
for 2 seconds again.

Disabling the pump alarm
software Version 1.2 and later
The display will show for 5 seconds the blinking operation mode of the
controller (CO or CU) and then for another 5 seconds it will show the value of
hysteresis set (e.g. H4).
To do this, enter the menu of the controller:
When this message is displayed, use buttons (
–
) or (
+
) to change this value to
"A 0", which means disabling alarm E 1.
The next setting is for stopping the alarm of E 1 pump; the display will show
blinking message "A 1" (default setting), which indicates active fire alarm.
In specific situations, it is possible to disable the alarm of disconnected or
damaged E 1 pump. It can be done in the case of connecting a pump with a low
power or electronically controlled.
Change the settings by simultaneously pressing and holding buttons (
–
) and (
+
)
for 5 seconds.
