8.4. DHW
This algorithm is used to control DHW pump. The following settings need to be configured properly:
Pump activation threshold - this option is used to set the device activation temperature (measured by the heat
source sensor which reads the temperature of the heat source e.g. CH boiler). Below this temperature the
device remains inactive; above this value the device is enabled and operates until the pre-set temperature is
reached.
Hysteresis - the temperature difference between device activation and its deactivation. Once the pre-set
temperature is reached, the device is disabled. It is enabled again when the temperature measured by the sensor
drops below the pre-set temperature by hysteresis value ((e.g. when the pre-set temperature is set at 60°C and
the hysteresis value is 3°C, the device will be disabled when the temperature reaches 60°C and it will be enabled
when the temperature drops to 57°C).
Pre-set DHW temperature - this parameter is used to define the pre-set temperature. Once it is reached, the
device is disabled. The temperature is measured by DHW sensor.
