6.3. Managing ground-connected heat exchanger
6.3.1. Operational description
The Duolix MAX can control a ground-connected heat exchanger valve.
The principle is to supply the Duolix MAX central unit via the ground-connected heat exchanger fresh
air inlet when the external air is below the minimum threshold (5°C for example) or above the max.
threshold (25°C for example) in order heat the fresh air in winter and cool it in summer.
Within the temperature range between these thresholds, the duct is negligible, it is therefore
preferable to pass through the fresh air inlet directly.
The Duolix MAX controls this valve by managing the source of fresh air used in the house.
N.B.:
These min. and max. thresholds can be adjusted in accordance with the installation. (See chapter 5.4.10)
6.3.2. Ground-connected heat exchanger wiring
Connector kit part no: 412,093
Ground-connected heat exchanger kit (All or Nothing valve RR125-M1 part no. 523 845; 1 kohm ext.
sensor part no.: 412 094)
The valve should be placed on the fascia air inlet and in the normally closed position (see diagram above).
If the external temperature is below 5°C or greater than 25°C (default) the air will pass through the
ground-connected heat exchanger and OUT5 will activate.
