HVAC Products 10 DHW heating 05.02.2007
During DHW heating, there is no restriction for the heating circuits with regard to heat
consumption.
But the heat source provides maximum limitation of the temperature for DHW heating.
If the heat source does not reach the required flow temperature setpoint, the amount of
heat drawn by the heating circuits will be restricted by a load reduction. Apart from that,
the heating circuits can draw heat without any restriction.
The heat source provides maximum limitation of the temperature for DHW heating.
During DHW heating, the heating circuits are not allowed to draw any heat.
The heat source delivers the temperature to satisfy the heat demand for DHW heating.
With regard to heat consumption during DHW heating, there are no restrictions for the
heating circuits.
The heat source delivers the temperature according to maximum selection of DHW
heat demand and heat demand from other consumers.
If the heat source does not reach the required flow temperature setpoint, the amount of
heat drawn by the heating circuits will be restricted via load reduction. Apart from that,
the heating circuits can draw heat without any restriction.
The heat source delivers the temperature according to maximum selection of DHW
heat demand and heat demand from other consumers.
The priority function only acts on the heating circuits, not on ventilation systems.

10.11.2 Primary flow temperature sensor
With plant types DHW 4 and DHW 5, a primary flow temperature sensor can be config-
ured as an option.
In that case, mixing valve control with plant type DHW 4 is accomplished via the pri-
mary flow temperature.
If the primary flow temperature sensor is configured, its temperature will be used during
active DHW charging to ensure discharging protection.
The function is to be activated via “Extra configuration”:
Main menu > Commissioning > Extra configuration > DHW > Inputs > Primary flow
sensor
