Particular attention has to be given where children and vulnerable people are present.
The fan heater is available in four sizes: AW 12, AW 22, AW 42, and AW 62. All models have a three-speed fan as
standard. The fan heater is protected to IP44 and may be installed in dry, damp, and wet rooms. The AW-a model is
delivered with valve. See attachment A for technical data on the fan heaters.
AW 12s, -22s, -42s, -62s.
These fan heaters do not have built-in controls. Controlling the fan and the water supply is done using external
components. For locations where there is risk of frost, frost protection must be used.
AW 12a, -22a, -42a, -62a.
The fan heater has built-in controls and is to be used where there is no risk of frost. The fan heater has an
electronic three-stage thermostat that controls the speed of the fan in three levels according to requirements.
The thermostat works by running the fan when needed, i.e. the fan stops when there is no heating requirement.
This minimises dirt contamination of the water coil and filter, if fitted. Even the speed regulation, which adjusts the fan
to the lowest possible air volume, reduces contamination.
The three-stage regulation also means that the fan heater can operate at the lowest speed for most of the year, thereby
minimizing the noise level.
The water flow is controlled by a valve actuator. The opening and closing times are 15 seconds. The valve opens at the
same time that the fan starts turning at slow speed.
A room sensor with temperature setpoint control (TG-R430) or room sensor (TG-R530 or TG-R630) with separate
temperature setpoint control (TG-R430) is required for regulation. The step differential for the thermostat is 1°C.
As an alternative to the TG-sensor, an external 0... 10V DC control signal may be connected to the electronic thermostat.
AW-a also has an outgoing control signal. This function exists irrespective of if you use a TG-sensor or an incoming
0... 10V DC control signal. The outgoing control signal can control up to five other AW-a or CAW-a (the CAW-a is the
VEAB range of ceiling-mounted fan heaters). If you want to connect more than 5 fan heaters from a common sensor or
0... 10V DC control signal, an outgoing control signal from a slaved AW-a has to be used. Sample schematics for
connecting sensor or control signal can be found in appendixes G, H, I and K in this pamphlet.
Accessories AW a-s (see appendix B)
Filter AWPF.
A flat filter to be fitted between fan and water coil
in AW 12-62.
Air deflector AWLH.
The standard air grille fitted, deflects the air downwards.
The optional part AWLH deflects the air sideways.
Induction louvre AWLA
Extends the throw with an average of 40%. Can not be
used together with AWLH. To be mounted in accordance
with separate instruction.
Wall bracket AWH.
Used for hanging the fan heater on the wall, or on the
ceiling, to give a vertical air stream.
Ceiling bracket AWT.
Used for hanging the heater from the ceiling to give a
horizontal air stream. May also be used together with
the wall bracket.
