Joint alarm
If the unit is located in a place where access is poor or infrequent, and if the control panel is also located here, it may be hard to observe
any alarms.
An external alarm in the form of a light or acoustic signal, etc., can be connected to the unit.
Cooker hood and EM box
There are several benefits from connecting the cooker hood to the home’s ventilation system. Firstly, there is full heat recovery of
heat from cooking.
Secondly, the unit is able to provide balance in the ventilation. If the cooker hood does not run via the ventilation and if the house is new
and airtight, use of the cooker hood will create a negative pressure in the home, minimising the suction effect from the cooker hood
and also creating smoke problems, for instance if a wood-burning stove or open fire is installed and in use. By running the cooker hood
via the unit, the unit can increase the supply air as the volume of extract air from cooker hood operation goes up. In this way, a balance
can be maintained in the home, and the cooker hood will retain its full suction power.
In the case of ventilation of a large home/building, with more than one bathroom, there may be problems creating sufficient air capa-
city for the cooker hood. In these cases, an EM box will be an ideal addition, as it minimises the extract air from the other high-humidity
rooms for the short period that the cooker hood is in use, and in this way ensures sufficient air for extraction via the cooker hood.
The potential free contact for the cooker hood is connected to user selection 1 or 2, which are programmed in the unit's software under
the section ‘General settings’. User selection 2 is chosen if an EM box is to be installed.
ATTENTION
If the cooker hood is connected to the ventilation system, it is important that it is fitted with a good grease filter and that
this can be regularly cleaned.
