5.4.3
PAUSE IN SUSTAIN MODE
This option is used to configure the pause time of the fan in sustain mode.
NOTE
Incorrect settings may lead to constant temperature increase! Pause in sustain mode should not be too short.
5.4.4
FAN SPEED IN SUSTAIN MODE
This option is used to adjust the fan speed (blow force) in sustain mode.
5.5
M
ANUAL MODE
For the user's convenience, the regulator offers the Manual mode module. In this function, each device (fan, CH pump, DHW
pump, additional pump 1, additional contact) is switched on and off independently of the others.
Press the pulser knob to enable a given device. The device remains active until the pulser knob is pressed again.
Additionally, blow force function enables the user to set any speed of the fan in manual mode.

P
UMP OPERATION MODES
This function enables the user to choose one of the following operation modes of the CH boiler.
MAIN
MENU
5.6.1
HOUSE HEATING
When this function is selected, only the house is heated. CH pump is activated when the temperature is above the CH pump
activation threshold. Below this temperature value (minus hysteresis) the pump is disabled.
5.6.2
WATER TANK PRIORITY
In this mode, DHW pump operates until the pre-set water tank temperature is reached (the valves close to the maximum and
the valve pumps are switched off). After the pre-set water tank temperature has been reached, the pump is disabled and the
controller activates the CH pump and the mixing valves. When the water tank temperature drops below the pre-set value minus
hysteresis, DHW pump is enabled again and the valves are disabled.
NOTE
If the water tank temperature is higher than the CH boiler temperature, the pump will not be activated in order not to
cool down the water in DHW tank.
5.6.3
PARALLEL PUMPS
In this mode, the CH pump operates above the pump activation threshold. DHW pump is activated at the same time in order to
heat the water tank. Once the pre-set DHW temperature has been reached, DHW pump is disabled. It is enabled again when the
temperature drops by DHW hysteresis value.
NOTE
If current CH boiler temperature is lower than current water tank temperature, DHW pump will not be activated to
prevent the water in the tank from cooling down.
