General Description; Briefly - Gewiss Chorus GW 10 799 Installationshandbuch

The KNX flush-mounting temperature adjustment probe is used, with the aid of a
KNX timed thermostat (GW 10 794 - GW 12 794 - GW 14 794) or a KNX thermostat (GW
10 795 - GW 12 795 - GW 14 795), to manage the temperature of the environment where
it is installed (or of another environment when used with an external temperature sensor).
The probe is not equipped with its own visualisation and command elements, so it must
be used with a KNX device (e.g. a KNX thermostat or a KNX timed thermostat) that can
control its parameters (HVAC or Setpoint mode and operating type).
The temperature adjustment probe 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 types of control: HVAC or Setpoint
• 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)
• 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 that can be configured for an NTC external temperature sensor (e.g. protection
sensor for underfloor heating) or, alternatively, a potential-free contact.
The probe is powered from the BUS line, and is equipped with a front signalling LED and
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).
