Control Modes; Operating Modes - Chorus Gewiss GW 16 974CN Installationshandbuch

The thermostat can be set with 2 different control modes:
• Slave: the functioning depends on the device configured as the Master (e.g. the
GW1x794H KNX flush-mounting timed thermostat), that sets the type, operating mode
or set-point of the thermostat on the basis of the ETS parameterisation. In the first
case (modes), the thermostat uses the set-points configured via ETS. These can be
modified locally and via the BUS if these options are enabled in the ETS configuration.
The fixed temperature set-point can be temporarily forced, but the operating mode
cannot be altered. The forced set-point will remain valid until the master device sends
a new operating mode. In the second case (setpoints), the thermostat uses the
setpoint received from the master device, which, at any rate, can always be altered
locally.
• Autonomous: the 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 thermostat to receive remote mode-setting
commands (OFF/Economy/Pre-comfort/Comfort) and type-setting commands
(Heating/Cooling). Such commands may be sent from other devices such as a push-
button or the KNX panel/supervisor.
The thermostat has 4 different operating modes:
• ECONOMY
• PRE-COMFORT
• COMFORT
• OFF - ANTIFREEZE/HIGH TEMPERATURE PROTECTION
In the autonomous control mode, to switch from one HVAC mode (economy, pre-comfort,
comfort, off) to another, use the
mode and the relevant setpoint are displayed with a blinking light.
In the slave control mode, no local modification of the HVAC mode is allowed; only the
manual switch-off (if enabled) of the device is possible (HVAC OFF).
