Increase temperature during domestic water heating - Closing thermostat
contacts means that boiler operation will follow according to the temperature
programmed with the thermostat knob. If domestic water tank heating is necessary,
the desired boiler temperature is higher in relation to the desired domestic water by
the selected value in this setting. In case of simultaneous operation of the room
thermostat and domestic water tank heating, the controller operation will follow to
maintain the higher boiler temperature. This setting is available, if domestic water
path „EXISTS” setting was selected.

Domestic water pump work extension - quick switching off of the pump refilling
domestic water tank may result in excessive rise of boiler temperature. This
parameter enables switching on of domestic water pump extension. This setting is
available, if domestic water path „EXISTS” setting was selected.

Domestic water pump extension time - this parameter specifies the time lapse
when domestic water is switched off since the moment when the programmed
temperature of domestic water tank was obtained. This setting is available, if
domestic water path „EXISTS” setting was selected and pump extension was
selected.

Mixing pump engaging temperature - this parameter specifies required return
water temperature so that the mixing pump engagement follows the controller. This
parameter is available if domestic water path „MIXING PUMP” setting was selected.

Mixing pump work hysteresis - this parameter specifies required return water
temperature increase in relation to the mixing pump engagement temperature so
that the controller switches off the mixing pump. This parameter is available if
domestic water path „MIXING PUMP” setting was selected.
