The timed thermostat can be set with 2 different control modes:
•Master: the timed thermostat sets the type, operating mode or set-point of the devices
configured as slaves (for example the flush-mounting Easy thermostats GW1x765). In the first
case (modes), the thermostats use the locally set set-points. The fixed temperature set-point
can be temporarily forced (max variation ± 3°C), but the operating mode cannot be altered.
The forced set-point will remain valid until the master device sends a new operating mode. In
the second case (set-points), the thermostats use the set-point received from the master device,
but which can always be altered locally (max ± 3°C).
•Autonomous: the timed thermostat type and operating mode can be set locally. Operation is
not dependent on any other device. In the autonomous control mode, you can alter the set-point
as you wish, and enable the timed thermostat to receive remote commands to modify the set-
point with regards the mode (OFF/Economy/Pre-comfort/Comfort) and type setting
(Heating/Conditioning). Such commands may be sent from other devices such as a push-button
or the Easy GSM remote control.
The timed thermostat has 5 different operating modes:
• AUTOMATIC
• ECONOMY
• PRE-COMFORT
• COMFORT
• OFF - ANTIFREEZE/HIGH TEMPERATURE PROTECTION
In any control mode (autonomous or master), to switch from one HVAC mode (economy, pre-
comfort, comfort, off) to another, use the button key: each time it is pressed, the
corresponding set-point is shown (flashing) for a moment.
In automatic operation mode, the timed thermostat uses a
program that can be differentiated for each day of the week.
The display shows the word AUTO, the detected room
temperature, and the symbol of the set-point for the current
quarter hour period. In the hourly profile, the column relating
to the current hour flashes, showing the current set-point.
In the economy, pre-comfort and comfort operating modes,
the timed thermostat always uses the corresponding
temperature set-points.
The display shows the detected room temperature and the
, or symbol.

MEANING OF
The anti-freeze function is only active in heating mode,
when the temperature adjustment system is switched OFF.
In this case, the timed thermostat uses the setpoint
temperature set-point, only reactivating the heating system
if the room temperature falls below TANTI-FREEZE.
The display shows the word OFF, along with the detected
room temperature.
The high temperature protection function is only active
in conditioning mode, when the temperature adjustment
system is switched OFF.
In this case, the timed thermostat uses the setpoint
protection set-point, only reactivating the conditioning
system if the room temperature exceeds THIGH TEMPERATURE
PROTECTION.
The display shows the word OFF, along with the detected
room temperature.
In the Master control mode, the display shows the
temperature and the symbol. The slave devices use the
operating mode or the set-point value received from the
timed thermostat (master device) via the BUS.

During operation, the activation of heating or conditioning mode is indicated in the
following way:
Heating
The symbol indicates that the activation command was sent
to the actuator that controls the boiler or area solenoid valve. If
the timed thermostat does not receive confirmation of effective
implementation from the actuator, the symbol will start to
flash. Subsequently, the timed thermostat sends the activation
command every 60 seconds until it receives confirmation.
Air-conditioning
The symbol indicates that the activation command was
sent to the actuator that controls the air conditioner or area
solenoid valve. If the timed thermostat does not receive
confirmation of effective implementation from the actuator,
the symbol will start to flash. Subsequently, the timed
thermostat sends the activation command every 60 seconds
until it receives confirmation.
peration with active fan coil control
If the fan coil control was activated, the symbol will
appear on the display. In addition, you will be offered the
page on which you can manually alter the fan coil speed or
set the AUTO mode (whereby the fan coil speed is
automatically adjusted on the basis of the difference
between the set-point fixed on the device and the detected
temperature).
Timed thermostat operation statuses
The timed thermostat has four distinct operation statuses:
- Normal operation
- Parameter setting
- Hourly profile programming
- Easy channel localisation mode
When it is switched on, the timed thermostat goes into "normal operation" status. Using
the button key, you can switch from one status to another (the switchover from
parameter setting status or hourly profile programming status of from Easy channel
localisation mode to normal operation status also takes place automatically, 30 seconds
after pressing last on the button keys).
