Maximum temperature – this option is used to set maximum temperature of source sensor. Once it has been
reached, the device is enabled and remains active until the source temperature drops below maximum
temperature by 2°C or DHW sensor temperature exceeds the source temperature. This function serves as
protection against system overheating.
Source sensor - this option is used to select the sensor which will provide temperature data necessary for
controlling the device connected to additional contact.
DHW sensor - this option is used to select the sensor which will provide temperature data necessary for
controlling the device connected to additional contact (pre-set temperature).
Example:
Part of the heating system is handled by buffer and pump. Pump is connected to additional contact. Buffer temperature
is read from sensor T4 (CH) and water tank temperature is read from sensor T5 (DHW).
The contact is activated when:
- Source temperature exc
eeds <pump activation threshold
> - Pre-set DHW temperature has not been reached
- Source sensor temperature is higher than T5 sensor temperature
If source temperature exceeds <maximum temperature>, the pump will be enabled in order to transfer the excess heat
from the heat source.
