DEVICE DESCRIPTION

The EU-T-3.2 room regulator is intended for controlling the heating device. Its main task is to maintain the pre-set flat/floor temperature by sending a signal to the heating device (contact closing) or the main controller which controls the actuators, when the room/floor temperature is below the pre-set value.
The EU-T-3.2 regulator functions:

• Maintaining pre-set room temperature
• Manual mode
• Day/night mode
• Control of the floor sensor
• Possibility of pairing with the EU-MW-3 module

Controller equipment:

• Touch buttons
• Front panel made of glass
• Built-in temperature sensor
• Batteries

There are 2 color versions

|

EU-T-3.2 works with an additional EU-MW-3 signal receiver (included in the controller set), mounted near the heating device.

HOW TO INSTALL THE CONTROLLER

**NOTE
The device should be installed by a qualified person. In order to mount the regulator on the wall, screw the rear cover onto the wall, insert batteries and slide the device into the cover. The EU-T-3.2 room regulator – connection diagram
Use the diagram below to connect the regulator – a two-wire communication cable should be connected to the appropriate connectors on the receiver. The room regulator should be connected to the heating device with a two-core cable. The cable connection between both devices is shown in the diagram below:: ****NOTE**
The regulator is powered with batteries – it is recommended to check the batteries from time to time and replace them at least once every heating season.

WIRELESS CONTROLLER RECEIVER

The EU-T-3.2 regulator communicates with the heating device (or the CH boiler controller) by means of a radio signal sent to the receiver. Such a receiver is connected to the heating device (or the CH boiler controller) by means of a twocore cable, and communicates with the room regulator using a radio signal. The receiver has three control lights:

• red control light 1 – signalises data reception;
• red control light 2 – indicates receiver operation;
• red control light 3 – goes on when the room temperature fails to reach the pre-set value – the heating device is switched on.

NOTE
In case of no communication (e.g. due to discharged battery), the receiver automatically disables the heating device after 15 minutes.

FIRST START-UP

In order for the EU-T-3.2 controller to work properly, it is necessary to follow these steps when starting the device for the first time:

1. Insert the batteries – in order to to do it, remove the front cover of the controller.
2. Connect the controller to the heating device.
3. If the room regulator will be used to operate the floor heating system, connect an additional sensor to the floor sensor connector.

HOW TO USE THE CONTROLLER

1. PRINCIPLE OF OPERATION
   The EU-T-3.2 room regulator is designed to maintain the pre-set room temperature by sending a signal to the heating device or the main controller when the pre- set room temperature has been reached. After receiving such a signal, the heating device turns off.
   NOTE
   For the floor heating functions to be available, the floor sensor must be enabled in the controller menu.

2. OPERATION MODES
   The room regulator may operate in one of the following operation modes:
   • Day/night mode – In this mode the pre-set temperature value depends on the current time of the day. The user may set different temperature values for the daytime and nighttime as well as define the exact time of entering day mode and night mode. In order to activate this mode, press MENU button until one of the mode icons appears on the main screen. The user may define the pre-set temperature and (after tapping on MENU again) the time of entering day and night mode.
   • Manual mode In this mode, the pre-set temperature is adjusted manually from the main screen view with the use of these buttons: Manual mode is activated after pressing MENU button. Once the manual mode has been activated, the previous operation mode enters ‘’sleep mode’’ until the next pre- programmed temperature change. Manual mode may be deactivated by pressing EXIT button.
