8.4 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.
8.5 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.
8.6 The stabilization time after heating hot water – during the preparation of hot
water priority enabled all the power boiler is used to heat water. Temperature of the
boiler during operation for hot water is often higher than the required heating circuit.
In addition, the CH pump off when working with hot water priority can cause hypot-
hermia heated rooms and a room thermostat input activation. In this case, after wor-
king for the hot water boiler water temperature may be higher than the temperature
required to heat the rooms. This may result in extinction of the burner due to excee-
ding the hysteresis top of the boiler. This parameter specifies how long is needed to
stabilize the system after the hot water tank with priority enabled. During the stabili-
zation controller disable checking hysteresis top and suspend the operation of the
adaptive algorithm of the room thermostat. This parameter is available only when hot
water is on track.
CAUTION! This feature does not work if water preparation is done without priority or
the controller is in summer mode.
8.7 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.
8.8 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.
8.9 Heating up the boiler for DHW – when the parameter is set to 'OFF', the con-
troller does not start to heat up the DHW until contacts of the thermostat input are
closed.
9.x Boiler work parameters.
9.1 Minimum boiler temperature – this parameter specifies boiler temperature
when the controller shall switch off central heating and domestic water pumps. It is
