The wall EIB 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 Building Automation KNX/EIB bus and control the heating or air-conditioning systems.

When combined with wall EIB thermostats (GW10 793 - GW14 793), it can be used with master functions to regulate the temperature in zones.

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 operation modes: OFF, Economy, Precomfort, Comfort and Automatic;
• 4 temperature settings for the heating function (T ECONOMY, TPRECOMFORT, TCOMFORT, TFROSTPROTECT.)
• 4 temperature settings for the air conditioning function (TECONOMY, TPRECOMFORT, TCOMFORT, THIGH TEMPERATURE PROTECTION).

The timer-thermostat is powered by the 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), alkaline batteries (AAA) to maintain the date and time on the display should the power be disconnected from the bus.

GENERAL DESCRIPTION

The timer-thermostat has 5 different operation modes:

AUTOMATIC
ECONOMY
PRECOMFORT
COMFORT
- 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, orT. T: T appear on the screen.

MEANING OF T. T: T:

Symbol	Heating Air conditioning
	Set point	Operation mode	Set point	Operation mode
Tc	TECONOMY	Economy	TCOMFORT	Comfort
Tt	TPRECOMFORT	Precomfort	TPRECOMFORT	Precomfort
Tf	TCOMFORT	Comfort	TECONOMY	Economy

GENERAL DESCRIPTION

The frostprotect. function is only enabled in heating function mode, when the thermal regulation system is OFF. 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 TFOSTPROTECT. 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 load notice has been sent via the ETS and 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 load notice has been sent via the ETS and 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.
