Unregulated sub-soil heat
exchanger The unit can only control the Zehnder sub-soil heat exchanger called ComfoFond-L
Q. When a different controlled sub-soil heat exchanger is necessary, the sub-soil heat
exchanger must have its own control system.
Extractor hood
(non powered)
Never install a powered extractor hood on the same ducting as the unit. This
will compromise the performance of the system.
Install at least 3m of air duct between the extractor hood and the unit. This will protect the
heat exchanger from the dirt removed by the extractor hood.
