FUNCTIONS
The thermostat maintains the temperature
set for the room.
The FMT20AW control panel is equipped
with the following functions:
- Selection of the working mode
A u t o m a t i c , H e a t i n g , C o o l i n g ,
Ventilation Only.
- Manual season change.
- Automatic season changeover, air side.
- Water minimum temperature control
( h e a t i n g ) a n d wa t e r m a x i m u m
temperature control (cooling) by means
of the SWA accessory, for 2-pipe
systems without resistance.
With the accessory, ventilation is
prevented if the temperature of the
system water is not suitable for the
functioning mode, thus guaranteeing
comfort and energy saving.
- manual choice of the ventilation speed;
- automatic choice of the ventilation
speed on the basis of the room
temperature;
- thermostat-controlled ventilation;
- continuous ventilation;
- Ventilation only functioning mode.
- visualisation of the set temperature;
- visualisation of the set ventilation
speed;
- visualisation of the Heating working
mode;
- visualisation of the Cooling working
mode;
- visualisation of the Automatic working
mode;
- start-up of the fan coil, maintaining the
settings used before the last switch-off;
- after a power failure, the fan coil
restarts keeping the the settings that
were active before the power failure;
- air temperature probe incorporated in
the panel;
- SWA external probe accessory (length
L=6m). It detects the temperature of the
room air if connected to the connector
( A ) . Th e r o o m a i r t e m p e ra t u r e
probe, incorporated in the panel, is
automatically disabled. t detects the
temperature of the water in the system
for ventilation consent if connected to
the connector (W). Two SWA probes
can be connected simultaneously to
the FMT20AW panel.
VENTILATION
Controls the ventilation, at three speeds
which can be selected manually or
automatically.
The ventilation speed is set by means of
the thermostat button
.
Manual management
- the fan uses the
On-Off cycles on the selected speed.
Automatic management
- visualisation
, the fan speed is managed by the
microprocessor.
The automatic management of the speed
is used in the Cooling, Heating and
Automatic modes.
The minimum working time between
one speed and another is 30 seconds.
“VENTILATION ONLY” mode
The VENTILATION ONLY mode allows
for the working of the fan coil even
when the hydraulic system is switched
off; in the event that cold or hot water
is circulating, the ventilation will be
continuous and not controlled by the
thermostat.
CONTINUOUS VENTILATION
The ventilation continues to work even
if the set temperature is reached, so the
temperature is therefore controlled by
means of the opening and closing of the
water valve(s) inserted in the system.
Do not use this setting in systems
without water interception valves, as
the ventilation will be continuous, and
not controlled by the thermostat.

VENTILATION
The ventilation switches off automatically
when the set temperature is reached.
MINIMUM/MAXIMUM water temperature
(Tw) check with SWA accessory(for
thermostat-controlled ventilation)
If the water is not suitable for the
functioning mode, the icon
will
flash slowly on the screen.

Tw = Water temperature
Ta = Air temperature
ALARMS:
If Tw<1°C or Tw>80°C, the icon
is displayed. The thermostat continues
operating without checking the water.
If Ta<5°C or Ta>40°C, the icon
will flash quickly on the screen, the
thermostat closes the valve/s and turns
off ventilation.
AUTOMATIC CHANGEOVER, AIR SIDE
Function active only in AUTOMATIC
mode.
The control allows to automatically
establish the functioning mode of the
fan coil in Heating or in Cooling mode
depending on the temperature set and
the room temperature detected by the air
probe.
We'd like to congratulate you on your purchase of the Aermec FMT20AW electronic
control panel with thermostat. Made from high quality materials, entirely in
compliance with the safety standards, “FMT20AW” is easy to use and long-lasting.
The
FMT20AW
regulating thermostat
is a control panel for fan coils, to be
assembled on the wall.
It controls the working of the fan coil on
the basis of the mode set and the room
temperature, to maintain the desired
temperature.
The panels must be wall-mounted. They
are used on systems with 4 tubes, 2
tubes and 2 tubes with resistance, with
the possibility to connect two valves of
the On-Off type for the interception of
the water to power the batteries.
Each control panel can control a single
fan coil.
The control panel only consists of mains
voltage (230V 50Hz) electrical circuits;
all the inputs for the probes and controls
must therefore be correspondingly
insulated for this voltage.
The valve servo commands must also be
scaled for 230V 50Hz.
FMT20AW must only be installed by
specialised personnel.
Disconnect the power supply before
b e g i n n i n g a n y i n s t a l l a t i o n o r
maintenance operations. Touching live
components could electrocute you.
