1 Introduction
The omfoSense (henceforth called
“device”) is a control device for residential
ventilation units (henceforth called
“ventilation unit” or “HRU”). The device
can be used for the omfoAir Luxe,
omfoD Luxe, WHR Luxe, WHR plus, G90
and Santos Standard.
The device is designed for the following
purposes:
1. To set a ventilation program for the
ventilation unit (auto);
2. To set the ventilation volume of the
ventilation unit (manual);
3. To set the parameters of the
ventilation unit (P menus).
There are 3 different variations of the
device (as shown on the front page):
omfoSense 55, 67 and H.
With these 3 variations the device can be
built-in in almost every standard frame.
In addition, the omfoSense 67 is also
available with a wall-mounting casing.
Applicable pictograms
Point to watch.
Risk of:
- Damage to the device;
- Performance of the
ventilation unit is
compromised if instructions
are not observed carefully.

Electrostatic discharge (ESD)
There is a risk that P Bs may be
damaged by an electrostatic discharge if
the electronics have to be replaced. For
this reason, always take ESD-inhibiting
measures when dealing with P Bs, such
as wearing an antistatic wristband.

temperature to the same
temperature as the room
thermostat (of the central
heating system).

When wanted, the supply (IN) or exhaust
(OUT) fan of the ventilation unit can be
turned off manually. This may be desired to
keep out unpleasant odors from outside.
Bear in mind that switching off a fan will
temporarily immobilize your dwelling’s
balanced ventilation system, so do not
forget to turn the fans on again.
When can the FAN not be switched?
To prevent air being sucked back from
the chimney of a fireplace the ventilation
unit is fitted with an open fire program.
When needed the installer or maintenance
mechanic can turn this program on. If
the fire program is turned on the supply
(IN) fan and exhaust (OUT) fan cannot be
turned on or off manually.
When can de supply (IN) fan not be
turned on?
The supply (IN) fan cannot only be
operated manually but can also be
controlled automatically by the ventilation
unit itself. This occurs in the winter to
protect the ventilation unit from freezing.
If the supply (IN) air is too cold for the
ventilation unit, the ventilation unit will
switch the supply (IN) fan automatically
off. In this case the supply (IN) fan cannot
be turned on manually.
