The single-phase 230 V electric motors have a
permanently installed capacitor and heat
protection is incorporated. Use of the
autotransformer means that 6 speeds can be
accessed. Three are standard and can be
selected from the control panel.
The motor is directly coupled to the fan(s) and
mounted on a flexible support and the system is
assembled to include a tray for collection of
condensation. Electrical connection with the
control panel is by rapid polarised insert.
The air filter is made of synthetic fibre and
mounted on a metal frame with a mesh net on
both sides. It can be extracted using the
unblocking flanges and a tool. In the FC and FCR
versions with casing, the air filter is supplied on
request.
The cover (F and FR versions) is made of zinc
plate and pre-painted in colour RAL 9002. It is
protected by transparent cling film to prevent
damage during transportation and installation. G
version are also available with a cover complete
with frontal intake grille in plastic and air filter.
The air output grille comes in modular form in
heat-resistant plastic in colour RAL 7032. The
right and left terminals include the site for the
control panel (F version) and the necessary
access flaps which have an exclusive trip closing
mechanism. In locations where access to the
control panel is not allowed (public places,
schools etc.) the access points can be closed
using the appropriate screw with head cover.
The F version fan heaters come as standard
with space for the control panel on the right
side.
The control panel is not included in the standard
fan heater pack because there are various different
models both for mounting on the appliance and
for remote mounting on a wall:
- Basic control panel 1
consists of an on-off switch for starting and
turning off the fan heater, a manual 3-speed
selector and an 'on' indicator light.
- Basic control panel 2
consists of a manual selector for OFF/
SUMMER/WINTER, a 3-speed manual selector
and an 'on' indicator light.
The control panel is set up for connection of a
thermostat (supplied separately) which means
that in the heating mode the fan is activated
only when the temperature of the water in the
heat exchanger exceeds a pre-set limit.
- Electronic thermostat 1
consists of an on-off switch for starting and
turning off the fan heater, a 3-speed manual
selector, and 'on' indicator light and a manual
SUMMER/WINTER selector.
The thermostat ensures automatic accurate
temperature control in heating and conditioning
plants with 2 pipes. The thermostat regulator
switch enables temperatures of from 5°C to
35°C to be programmed. The fan heater goes
off automatically when the desired temperatu-
re is reached.
- Electronic thermostat 2
consists of a manual OFF/SUMMER/WINTER
switch, a 3-speed manual selector and an 'on'
indicator light.
The thermostat includes all the functions of
electronic thermostat 1 and in addition can be
used with a 2-electrovalve control in 4-pipe
plants or 1 electrical resistance electrovalve
in 2-pipe plants. A minimum temperature
reading can also be included using an
appropriate connection (for use in winter
cycle).
- Microprocessor thermostat
Includes all the functions of the electronic
thermostats and in addition has automatic fan
speed selection and summer/winter switch. A
2 electrovalve control is possible in 4-pipe
plants and 1 electrical resistance electrovalve
in 2-pipe plants. A minimum temperature
reading can also be included (for winter use)
and a device for activating the energy saving
function.
