Pack content

The wall-mounting Easy Thermostat allows you to manage the temperature in the area it is installed in. 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 elements, including the fan coils. When combined with the wall Easy Timer Thermostat (GW 10 761 - GW 14 761), from which it receives the operation type and mode via the bus, it is possible to create multi-zone thermal regulation systems.

The set-point values used by the thermostat are set locally.

The thermostat has:

• 2 function types: heating and air conditioning;
• 4 operation modes: OFF, Economy, Precomfort and Comfort;
• 4 temperature settings for the heating function (Teconomy, Tprecomfort, Tcomfort, Tfrostprotect)
• 4 temperature settings for the air-conditioning function (Teconomy, Tprecomfort, Tcomfort, Thigh_temperature_protection);
• 3 control algorithm which can be set locally: with 2 points (ON/OFF command), PI (PWM type control) and a fan coil speed control (automatic or manual).

The thermostat is powered by the supplied bus line and is fitted with a timer backlit LCD display, 5 control buttons, an integrated sensor to detect the ambient temperature (the value of which is sent to the bus every 15 minutes), a rechargeable battery (included) to maintain the date and time on the display (when power is disconnected from the bus).

The thermostat output channels can be configured to:

• send the ON/OFF command to the KNX/EIB actuators (max 2) that control the heating / air-conditioning elements;
• regulate the fan-coil speed (max 3 speeds);
• transmit the settings (operation type and mode) and the current data (read temperature) to other devices, for instance the GSM remote control unit.

The thermostat input channels can be configured to:

• remotely control the thermostat operation type and mode with other KNX/EIB devices (for instance the timer-thermostat or the Easy GSM remote control unit);
• 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 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 round or square flush-mounted box.

Control modes

The thermostat can be set to 2 different control modes:

• Slave: the function depends on the device configured as Master (for instance the Easy EIB timer-thermostat GW 10 761), that set the thermostat operation type and mode. In this function mode the thermostat uses the set-point values that are set locally. It is possible to change the set temperature set-point (max variation ± 3^ ), whilst it is not possible to change the operation mode. The modified set-point will remain valid until the Master device sends a new operation mode.
• Stand alone: The thermostat operation type and mode are set locally. The operation status does not depend on any other device in Stand-alone mode it is possible to vary the set-point at will and enable the thermostat to receive remote commands from other devices, such as for instance a button or the EIB Easy GSM remote control unit GW 90 861.

Operation mode

The thermostat foresees 4 different operation modes:

ECONOMY
PRECOMFORT
COMFORT
- OFF-FROSTPROTECT/HIGH TEMPERATURE PROTECTION

In the STAND ALONE control mode use the key to switch from one mode to another. In the SLAVE control mode the key is not enabled, as the operation mode is set on the device configured as Master.

In the economy, precomfort and comfort operation modes the timer-thermostat permanently uses the corresponding temperature set-points. The current ambient temperature and the symbol ,T. T: o appear on the screen.

GENERAL DESCRIPTION

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

The frostprotect operation is only enabled in heating operation mode, when the thermal regulation system is OFF. In this case the thermostat uses the set frostprotect temperature set-point, re-starting the heating system only when the ambient temperature decreases below T FROSTPROTECT.

The message "OFF" and the measured ambient temperature are displayed on the screen.

The high-temperature protection operation is only enabled in air-conditioning mode, when the thermal regulation system is OFF.

In this case the thermostat uses the set high-temperature set-point, re-starting the air-conditioning system only when the ambient temperature exceeds the T HIGH TEMPERATURE PROTECTION

The message "OFF" and the measured ambient temperature are displayed on the screen.

USER INSTRUCTIONS

2 POINT CONTROL

The thermal regulation system is switched off when the ambient temperature is equal to the set point, and is switched back on when:

• the temperature is equal to or lower than the set point
• forTheating;
• the temperature is equal to or higher than the set point + for air-conditioning.

The diagrams below show the two function types. HEATING

AIR CONDITIONING

To avoid continuous switchings, the thermostat will wait for up to 2 minutes before sending the activation command to the actuator that controls the thermal regulation system.

USER INSTRUCTIONS

PROPORTIONAL CONTROL (PWM)

The proportional channel (from set point to set point T for heating, from set point to set point + for air-conditioning) is divided into four equal zones. At the end of each cycle time, the thermostat controls the ambient temperature and, according to the differences recorded, it modulates the proportion of the ON and OFF commands transmitted during the cycle time. The diagrams below show the behaviour of the proportional control in heating and air-conditioning operations.

USER INSTRUCTIONS

FAN COIL CONTROL

When the temperature reaches the set point value- T (in heating) or set point + (in air-conditioning) an ON message is sent to activate the fan coil for the selected operation type, and an ON message to switch on the fan coil at speed V1.

At set point-2 (in heat.) or set point +2 (in air-cond.) speed V2 is activated, at set point-3 (in heat.) or set point+3 (in air-cond.) speed V3 is activated.

USERINSTRUCTIONS

To avoid continuous switchings, the thermostat will wait for up to 2 minutes before sending the activation command to the actuator that controls the thermal regulation system or to the actuator channels that control the fan coil speed.

USER INSTRUCTIONS

Behaviour on the failure and reinstatement of the bus power supply

When the bus power supply fails, the device performs no actions.

The time and date are maintained by the buffer power system (rechargeable battery) whilst all the other settings are saved to a non-volatile memory.

When the power is supplied by battery only, the device has an autonomy of 36 hours in the following conditions:

• display time active;
  measure and temperature display not active (dashes are displayed);
• backlighting not active;
• front keys are not enabled (except for the simultaneous pressing of FAN and SET).

When there is no bus power the simultaneous pressing of FAN and SET for 2 seconds will cause the rechargeable battery to disconnect inside the device.

This function is used to conserve the efficiency of the battery when the device is not used for a long period. The battery is then automatically reconnected when the device receives power from the bus. The set programs are not lost when there is a failure in the bus connection or when the battery is disconnected.

The device is in full operation mode within a maximum of 5 seconds from reinstatement of the bus power supply.

If the buffer power (rechargeable battery) is absent or disconnected, the thermostat will restart in OFF mode when the bus power is reinstated.

USER INSTRUCTIONS
