The KNX flush-mounting thermostat is used to manage the temperature of the
environment where it is installed (or of another environment when used with an external
temperature sensor). 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 thermostat can work in "autonomous" control mode, to autonomously manage the
temperature adjustment system (or parts of it); when combined with the KNX flush-
mounting timed thermostat (GW 10 794 - GW 12 794 - GW 14 794), it can work in "Slave"
control mode to create multi-area temperature adjustment systems. The thermostat
allows you to visualise and independently modify the operating parameters of up to 4
KNX flush-mounting temperature adjustment probes (GW 10 799 - GW 12 799 - GW 14
799).
The Setpoint values used by the thermostat are the ones configured via ETS, and they
can be modified locally and via the BUS (if these options were enabled during the ETS
configuration).
The thermostat offers:
• 2 types of operation: heating and air conditioning, with independent control algorithms
• 4 operating modes: OFF (anti-freeze / high temperature protection), Economy, Pre-
comfort and Comfort
• 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: Slave (if combined with a Master device) or autonomous
• 2 types of control: HVAC or Setpoint
• the possibility to independently visualise/modify the parameters of up to 4 KNX
temperature adjustment probes
• 2 control stages: single stage (with single switchover command) or dual stage (with
dual switchover command, for systems with a high degree of thermal inertia)
• 2-way or 4-way systems control algorithms (first stage): 2 points (ON/OFF command
or 0%/100%), proportional PI (PWM or continuous control), fan coil (max 3 speeds)
• control algorithms (second stage): 2 points (ON/OFF command or 0%/100%)
• 1 relay output with NO/NC contact, that can be used by the thermostat or other KNX
command devices
• 1 input for a potential-free contact (e.g. a window contact, or as a general input with
command function on the BUS)
• 1 input for NTC external temperature sensor (e.g. protection sensor for underfloor
heating)
The 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, a built-in sensor for detecting the ambient temperature (whose
value is sent on the BUS at intervals that can be parameterised, or following a
temperature variation, depending on the ETS configuration).
