Pack contentEasy wall Timer-Thermostat allows you to automatically manage the temperature in the area it is installed in on a weekly basis. The temperature is regulated by the KNX/EIB actuators which are managed by the Home Automation KNX/EIB bus and control the heating or air-conditioning systems. When combined with the Easy wall Timer- Thermostats (GW10 763 - GW14 763 ), from which it receives the function type and mode via the bus, it is possible to create multi-zone thermal regulation systems. The temperature profiles are defined on a weekly basis. It is possible to programme an independent time profile for each day of the week, with a 15 minute resolution and without limits to the daily variations. The timer-thermostat comprises:

• 2 function types: heating and air conditioning;

• 5 function modes: OFF, Economy, Precomfort, Comfort and Automatic;

• 2 control algorithm which can be set locally: with 2 points (ON/OFF command) and PI (PWM type control). The timer-thermostat is powered by the supplied bus line and is fitted with a timed backlit LCD display, 10 control buttons, an integrated sensor to detect the ambient temperature (the value of which is sent to the bus every 15 minutes), alkaline batteries (AAA) to maintain the date and time on the display should the power be disconnected from the bus. The output channels can be configured to:

• send the ON/OFF command to the KNX/EIB actuators that control the thermal regulation system (max 2 for heating / air-conditioning);

• set the function type (heating/air-conditioning) and function mode (OFF/Economy/ Preconformt/Comfort)) for the zone thermostats;

• transmit the settings (function type and mode) and the current data (read temperature) to other devices, for instance the EASY GSM repeater – GW 90 861. The input channels can be configured to:

• remotely control the timer-thermostat function type and mode with other KNX/EIB devices (for instance the Easy GSM remote control unit - GW 90 861);

• manage scenes, associating a function type or mode to a specific scene;

• manage an incoming signal, for instance a contact when a window is opened, to temporarily switch off the timer-thermostat. The device is installed on the wall using the supplied flange that can be fixed to the wall using dowels or screwed onto a 3 module flush-mount box. GENERAL DESCRIPTION

SummaryThe timer-thermostat is fitted with a display, 3 control buttons which are always accessible and 7 control buttons which can be accessed when the cover is open. GENERAL DESCRIPTION

• OFF-FROSTPROTECT/HIGH TEMPERATURE PROTECTION Use the key to switch from one mode to another. When in automatic mode the timer-thermostat uses a programme that can be customised for each day of the week. The message “AUTO”, the measured ambient temperature and the set point symbol relative to the current quarter-hour are displayed on the screen. The column relative to the current time with the representation of the active set point blinks in the time profile. In the economy, precomfort and comfort function modes the timer-thermostat permanently uses the corresponding temperature set-points. The current ambient temperature and the symbol , o appear on the screen. MEANINGS OF GENERAL DESCRIPTION

In this case the timer-thermostat uses the set frostprotect temperature set-point, re-starting the heating system only when the ambient temperature decreases below TFROSTPROTECT. The message ”OFF” and the measured ambient temperature are displayed on the screen. The high-temperature protection function is only enabled in air-conditioning mode, when the thermal regulation system is OFF. In this case the timer-thermostat uses the set high- temperature set-point, re-starting the air-conditioning system only when the ambient temperature exceeds the

HIGH TEMPERATURE PROTECTION. The message ”OFF” and the measured ambient temperature are displayed on the screen. The activation of the heating or air-conditioning functions are indicated as followed: Heating The symbol indicates that the activation command has been sent to the actuator which controls the boiler. If the timer-thermostat does not receive confirmation from the actuator that the same has been activated, the symbol starts to flash. Subsequently, the timer-thermostat sends the activation command again, at one minute intervals, until it receives a positive response. Air conditioning The symbol indicates that the activation command has been sent to the actuator which controls the air- conditioner. If the timer-thermostat does not receive confirmation from the actuator that the same has been activated, the symbol starts to flash. Subsequently, the timer-thermostat sends the activation command again, at one minute intervals, until it receives a positive response.
