FUNCTIONS
The thermostat maintains the temperature
set for the room.
The FMT21 control panel is equipped with
the following functions:
- Selection of the working mode
Automatic, Heating, Cooling, Ventilation
Only.
- Manual season change.
- Automatic season changeover, air side.
- Water minimum temperature control
(heating) and water maximum
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). The room air temperature
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
FMT21 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.

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.

If Tw<1ยฐC or Tw>80ยฐC, the icon
is
displayed. The thermostat continues
operating without checking the water.
If Ta<1ยฐC or Ta>40ยฐC, the icon
will

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.

The FMT21 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.
