The Easy flush-mounting timed thermostat is used to automatically manage the
temperature of the environment where it is installed (or of another environment when
used with an Easy thermostat or with an outdoor temperature sensor) on a weekly basis.
The temperature is adjusted by commanding - on a KNX BUS - the KNX actuators that
control the heating or air conditioning elements, including the fan coils.
The timed thermostat can work in "autonomous" control mode, to autonomously manage
the temperature adjustment system (or parts of it); when combined with the Easy flush-
mounting thermostats (GW 10 765 - GW 12 765 - GW 14 765), it can work in "Master"
control mode to create multi-area temperature adjustment systems. The hourly profiles
are defined on a weekly basis. An independent hourly profile can be programmed for
each day of the week, with a 15 minute resolution and without any limit to the daily
variations. If an hourly profile is configured to control the HVAC or Setpoint mode of an
Easy flush-mounting temperature adjustment probe (GW 10 769 - GW 12 769 - GW 14
769) the profile parameters can be visualised.
The timed thermostat offers:
• 2 types of operation: heating and air conditioning, with independent control algorithms
• 5 operating modes: OFF (anti-freeze / high temperature protection), Economy, Pre-
comfort, Comfort and Automatic
• 4 heating adjustment temperatures (Teconomy, Tpre-comfort, Tcomfort, Tanti-freeze)
• 4 air-conditioning adjustment temperatures (Teconomy, Tpre-comfort, Tcomfort,
Thigh_temperature_protection)
• 2 control modes: Master (if combined with Slave devices) or autonomous
• 2- way or 4-way systems control algorithms: 2 points (ON/OFF command), proportional
PI (PWM type control), fan coil (3 speeds)
• 1 relay output with NO/NC contact, that can be used by the timed thermostat to
command the heating and/or air-conditioning solenoid valve
• 1 input for a potential-free contact (for the window contact function)
• 1 input for NTC external temperature sensor (e.g. protection sensor for underfloor
heating).
The timed thermostat is powered from the BUS line and is equipped with an RGB LCD
display with backlighting, a front light intensity sensor (for automatic display lighting
adjustment), 4 command push-buttons, and a built-in sensor for detecting the ambient
temperature (whose value is sent on the BUS every 15' and following a 0,5 °C
temperature variation).
There is also a housing for the alkaline batteries (AA, not included), so the date and time
are maintained in the event of a BUS voltage drop.
