The KNX 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 a KNX 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 KNX flush-mounting
thermostats (GW 10 795 - GW 12 795 - GW 14 795), 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 a KNX flush-mounting temperature adjustment probe (GW 10 799 - GW 12 799 -
GW 14 799), the profile parameters can be visualised.
The Setpoint values used by the timed 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 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
Thigh_temperature_protection)
• 2 control modes: Master (if combined with Slave devices) or autonomous
• 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 timed 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 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, 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). 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.
