e 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.e fan heater is protected to IP44 and may be installed in dry, damp, and
wet rooms.e AW-a model is delivered with valve. See attachment A for technical data on the fan heaters.
AW 12s, -22s, -42s, -62s.
ese 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.
e fan heater has built-in controls and is to be used where there is no risk of frost.e fan heater has an electronic three-
stage thermostat that controls the speed of the fan in three levels according to requirements.e thermostat works by
running the fan when needed, i.e. the fan stops when there is no heating requirement.is minimises dirt contamination of
the water coil and lter, if tted. Even the speed regulation, which adjusts the fan to the lowest possible air volume, reduces
contamination.
e 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.
e water ow is controlled by a valve actuator.e opening and closing times are 15 seconds.e 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.e step dierential 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.is function exists irrespective of if you use a TG-sensor or an incoming
0... 10V DC control signal.e outgoing control signal can control up to ve 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 unit AWK.
For ltration of the recirculated air to AW 22-62 (not AW 12).
Filter AWF.
Pleated lter for AW 22-62 (not AW 12). A large ltered area means longer intervals between replacement.
Reduces contamination of the fan and water coil.
Filter AWPF.
A at lter to be tted between fan and water coil in AW 12-62.
Air deector AWLH.
e standard air grille tted, deects the air downwards.e optional part AWLH deects 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.
