Page 7: Control Modes
GENERAL DESCRIPTION Control modes The thermostat can be set with 2 different control modes: • Slave: operation depends on the device configured as the Master (e.g. the KNX flush- mounting timed thermostat GW1x794H), that sets the type, operating mode or setpoint of the thermostat on the basis of the ETS parameterisation. -

Page 10: User Instructions
USER INSTRUCTIONS Thermostat operation statuses The thermostat has two distinct operation statuses: - Normal operation - Parameter setting When it is switched on, the thermostat goes into “normal operation” status. Using the button key, you can switch from one status to the other (the switchover from “parameter setting”... - Page 11 USER INSTRUCTIONS Forcing the setpoint manually If the displayed page relates to the thermostat and any HVAC mode other than OFF is active, press the button key to temporarily modify the setpoint of the active HVAC mode (within the adjustment limits set via ETS), then confirm with the button key or wait for the 5-second time-out period to elapse.
- Page 12 USER INSTRUCTIONS Pages relating to the remote elements Viewing the remote elements If the visible page relates to a remote element, press the button key to alternate the visualisation of the detected temperature and the setpoint; if one of these two figures is not available, nothing will happen when the button key is pressed.
- Page 13 USER INSTRUCTIONS Parameter setting To set the operating parameters of the thermostat, humidity, and any remote elements (e.g. KNX temperature adjustment probes), press the button key. To quit the parameter setting procedure without saving the modifications made on the current page, just press the button key again or wait 30 seconds from the last pressure on the button keys.
- Page 14 USER INSTRUCTIONS Setting the temperature measurement unit When the °C or °F temperature symbol begins flashing, select the temperature measurement unit by means of the button keys. To confirm your choice and move on to the next parameter, press the button key within 30 seconds.
- Page 15 USER INSTRUCTIONS Single-colour theme for icon colour Use the button key to modify the colour of the icons within a single-colour theme. This parameter is only visible if the icon theme is single-colour and the back-lighting is active. To confirm your choice and move on to the next parameter, press the button key within 30 seconds.
- Page 16 USER INSTRUCTIONS Operating parameters White balancing Use the button keys to set the weight of the red (RED), green (GRE) and blue (BLU) component in the backlighting of the display (value can be set between 1 and 63). The regulation only applies to the white colour of the screen.
- Page 17 USER INSTRUCTIONS If the displayed page relates to the thermostat (type of operation: heating) Setpoint setting When the symbol appears, the temperature value begins flashing. Adjust the value of (Teconomy) / with the aid of the button keys. To confirm the set value, press the button key within 30 seconds.

Adjust the value of ) with COMFORT the aid of the button keys. To confirm the set value, press the button key within 30 seconds.
- Page 19 USER INSTRUCTIONS If the displayed page relates to humidity Enabling the humidity thresholds (from 1..5) Use the button keys to enable (ON) or disable (OFF) the relative humidity thresholds (up to 5, if enabled in ETS). To confirm your choice and move on to the next parameter, press the button key within 30 seconds.

- Page 21 USER INSTRUCTIONS TWO POINTS 0%-100% The operating principle is similar to that of the two points ON-OFF, but with the difference that the communication objects for temperature adjustment management are of 1 byte. In heating mode, when the detected temperature is lower than the “setpoint - ”...
- Page 22 USER INSTRUCTIONS PWM PROPORTIONAL-INTEGRAL The PWM control algorithm, used to control the temperature adjustment system, allows you to drastically reduce the times subject to thermal inertia and introduced by the two- point control. This type of control involves the modulation of the impulse duty-cycle, represented by the temperature adjustment system activation time, on the basis of the difference between the fixed setpoint and the temperature effectively detected.
- Page 23 USER INSTRUCTIONS The device keeps the temperature adjustment system switched on for a cycle time percentage that depends on the output function of the proportional-integral control; the device continually adjusts the system, modulating the system ON-OFF times with a duty- cycle that depends on the value of the output function (calculated at each time gap equal to the cycle time).
- Page 24 USER INSTRUCTIONS function: the proportional component and the integral component, used to improve the response in order to reach the temperature at the fixed setpoint. Once the proportional band has been defined (from setpoint to setpoint - for heating mode, from setpoint to setpoint for cooling mode), its width determines the extent of the system response: if it is too narrow, the system will be more reactive but with swings;...
- Page 25 USER INSTRUCTIONS FAN COIL WITH ON-OFF SPEED CONTROL The operating principle involves activating/deactivating the fan coil speeds on the basis of the difference between the fixed setpoint and the detected temperature, using independent 1-bit communication objects to manage the individual speeds. The figures below refer to the control of the speeds of a fan coil with three operating stages for heating and cooling.

- Page 27 USER INSTRUCTIONS FAN COIL WITH CONTINUOUS SPEED CONTROL The operating principle is similar to that of the fan coil with ON-OFF speed control, but with the difference that there are no independent communication objects for managing the individual speeds - just one 1-byte object. The figures below refer to the control of the speeds of a fan coil with three operating stages for heating and cooling.
- Page 28 USER INSTRUCTIONS Speed V1 is activated when the temperature value is lower than the “setpoint - valve ” value (in heating mode) or higher than the “setpoint + ” value 1heat valve 1cond (in cooling mode), and deactivated (sending of “fan OFF” value) when the temperature value reaches the “setpoint - ”...
- Page 29 USER INSTRUCTIONS Setting the valve adjustment differential Use the button keys to set the value of the adjustment differential of the fan coil valve control algorithm (the gap can be set from 0.1°C to 2.0°C). If the control logic is common, the parameter remains the same in both heating and cooling mode.
- Page 30 USER INSTRUCTIONS Setting the inertia for speed 3 Use the button key to set the value of the inertia time for fan coil speed 3 (the gap can be set from 0 to 10 seconds). This parameter is visible if the fan coil speed number is 3.

Page 31: Setting The Parameters
USER INSTRUCTIONS Setting the parameters of the remote elements From the thermostat display, you can modify the parameters relating to the general remote element. The screens of the Set menu of the individual remote element are shown below. Repeat the programming for all the remote elements (P01, P02, P03, P04) that are present. To access the pages for setting the parameters of the remote elements, start from the visualisation screen of the required element (see Choosing the page you want to see - page 10), then press the... -

What does the temperature value on the display actually represent? If no external temperature probe is enabled during ETS programming, the value shown on the display is the temperature detected by the sensor in the thermostat. If, however, an external temperature probe (of the KNX or NTC type) has been enabled, the thermostat shows the average of the values detected by the probe and the sensor, using a variable weight between 10% and 100% (which can be defined via ETS).
- Page 34 USER INSTRUCTIONS What happens to the time band set on the thermostat if the BUS power supply fails and is reset? The thermostat has no buffer battery, so the time setting is lost if there is a BUS voltage failure. The time can be reset manually, or automatically via the BUS (defined via ETS) from a KNX device (timed thermostat, weather station, Master, Internet Gateway, etc.).
