The timed thermostat can be set with 2 different control modes:
•Master: the timed thermostat sets the type, operating mode or setpoint of the devices
configured as Slaves (e.g. the Easy flush-mounting thermostats GW1x765H). In the first case
(mode), the thermostats use the setpoints set locally. The fixed temperature setpoint can be
temporarily forced (max. variation ±3°C), but the operating mode cannot be altered. The forced
setpoint will remain valid until the master device sends a new operating mode. In the second
case (set-points), the thermostats use the setpoint received from the Master device (which can
always be altered locally with a max. variation of ±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 setpoint
as you wish, and enable the timed thermostat to receive remote commands to modify the mode
setpoint (OFF/Economy/Pre-comfort/Comfort) and set the type (Heating/Cooling) received 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 setpoint 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 setpoint for the current
quarter hour period. In the hourly profile, the column relating
to the current hour flashes, showing the current setpoint.
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 fixed anti-freeze
temperature setpoint, only reactivating the heating system
if the room temperature falls below TANTIGE O (Tanti-freeze).
The display shows the word OFF, along with the detected
room temperature.
The high temperature protection function is only active
in cooling mode, when the temperature adjustment system
is switched OFF.
In this case, the timed thermostat uses the fixed high
temperature
protection setpoint, only reactivating the cooling 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 setpoint value received from the
timed thermostat (master device) via the BUS.

During operation, the activation of the heating or cooling mode is indicated in the
following way:
Heating
The symbol indicates that the activation command has
been sent to the command actuator of the boiler or area
solenoid valve. If the timed thermostat does not receive
confirmation of effective implementation from the actuator,
the symbol will begin to flash. Subsequently, the timed
thermostat sends the activation command every 60 seconds
until it receives confirmation.
Cooling
The symbol indicates that the activation command has
been sent to the command actuator of the air-conditioner or
area solenoid valve. If the timed thermostat does not receive
confirmation of effective implementation from the actuator,
the symbol will begin to flash. Subsequently, the timed
thermostat sends the activation command every 60 seconds
until it receives confirmation.
Operation with active fan coil control
If the fan coil control function has been activated, the
display will show the symbol. 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 setpoint 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, “hourly profile programming” status” or “Easy channel
localisation mode” to “normal operation” status also comes about automatically, 30
seconds after the last pressure on the button keys.
