SHW hot water tank
The SHW hot water tank is connected to Compact P2 AIR connection panel as shown below. The SHW tank has its own power supply via
a Schuko plug.
User selection 1
User selection 1 is connected via the 8-pin plug mounted on top of the unit.
The user selection functions are used to override normal operation. The input signal must come from a potential-free switch. When
closed, the function is activated with the settings selected in the control panel under Service / User selection.
Some examples of the situations in which the user selection functions are used:
Connection via the 8-pin olug:
1. RJ45 plug for transmitting top
temperature (T21), bottom
temperature (T22) and anode
monitoring in the SHW tank.
2. Plug for control of supplemen-
tary electric heating in the SHW
tank.
Cooker hood If you choose to run the cooker hood over the ventilation unit, the cooker hood sends a potential-free signal to the
ventilation unit when it is switched on. When this happens, the ventilation unit increases the air volume to the set
level, so that enough air is extracted through the hood.
Fireplace/wood
burning stove
Normally, the ventilation is balanced with a small negative pressure in the home, so that no moisture is forced into
the building's construction. It is a disadvantage if you light up your fireplace / wood stove, as the smoke will then en-
ter the home instead of out of the chimney.
When you switch on the fireplace/burning stove, you can activate the user function with a potential-free switch,
which ensures that there is an overpressure in the home, so that the smoke smokes out of the chimney as it should.
Extended
operation
If the ventilation unit is used in an office or school where the ventilation is reduced outside the opening hours, it may
be necessary to turn it up briefly if, for example when a meeting is held in the evening.
There you can then have a switch that is activated and the ventilation is increased e.g. for an hour before it then goes
back into operation.
