TECH CONTROLLERS EU-293v3 Two State Room Regulators Flush Mounted

Product Information: EU-293 Room Regulator

The EU-293v3 room regulator is a device designed to control heating or cooling equipment such as gas, oil, or electric boilers or boiler controllers. Its primary function is to maintain a pre-set temperature in a room by sending a signal to the heating/cooling device to turn on or off when the desired temperature is reached. The regulator has advanced software that enables it to perform various functions such as manual mode, day/night program, weekly control, and underfloor heating system control (additional temperature sensor required).

The controller equipment includes touch buttons, a front panel made of 1mm glass, a built-in temperature sensor, and batteries for the battery-powered version. The regulator also has two display versions – standard (black data on a white background) and negative (white data on a black background). It is available in two color versions – white and black.

The device should be installed by a qualified electrician, and any use other than specified by the manufacturer is forbidden. It  is important to periodically check the device for any changes in the merchandise described in the manual that may have been introduced subsequent to its completion on 21.05.2021. The manufacturer retains the right to introduce changes to the structure or colors, and the illustrations may include additional equipment. Print technology may result in differences in the colors shown.

Advanced software enables the regulator to fulfil a wide range of functions:

• maintaining the pre-set room temperature
• manual mode
• day/night program
• weekly control
• underfloor heating system control (optional; an additional temperature sensor is necessary)

Controller equipment:

• touch buttons
• front panel made of 1mm glass
• built-in temperature sensor
• batteries (battery-powered version)

The EU-293v3 room regulator offers two display versions:

• standard (the data is displayed in black against white background)
• negative (the data is displayed in white against black background)

Two colour versions available

• WHITE

• BLACK

Hardware versions:

1. EU-293 B v3 – wired version, powered with two AAA 1,5V batteries, with a temporary backlight. Colour versions: black or white.
2. EU-293 Z v3 – wired version, powered with 230V, with a temporary backlight. Colour versions: black or white.

HOW TO INSTALL THE CONTROLLER

NOTE

• The device should be installed by a qualified electrician.

HOW TO INSTALL BATTERY-POWERED REGULATOR

• The EU-293v3 room regulator – connection diagram

The room regulator should be connected with the heating device with the use of a two-core cable. When connecting devices with a power greater than 1A, it is necessary to use a contactor. Optionally, it is possible to connect an additional sensor to the floor sensor contact contact – additional functions will appear in the controller menu.

The EU-293v3 room regulator may be used as a wall-mountable panel. In order to mount it, place the rear part of the controller in the mounting box on the wall, insert the regulator and turn it slightly.

HOW TO INSTALL 230V-POWERED REGULATOR

• The EU-293v3 room regulator – connection diagram

The room regulator should be connected with the heating device with the use of a two-core cable. When connecting devices with a power greater than 1A, it is necessary to use a contactor. Optionally, it is possible to connect an additional sensor to the floor sensor contact contact – additional functions will appear in the controller menu.

FIRST START-UP

In order for the EU-293v3 controller to operate correctly, follow these steps when starting the device for the first time:

1. Insert the batteries – in order to do it, remove the controller back cover (battery-powered version).
2. If the room regulator is to control the floor heating system, connect an additional sensor to the floor sensor connector.
3. Connect the regulator with the heating device using a two-core cable.

NOTE
Only one room regulator may be assigned to each zone. Assigning more than one room regulator will make it impossible for the external controller to work properly.

HOW TO USE THE CONTROLLER

PRINCIPLE OF OPERATION
The EU-293v3 room regulator is designed to maintain the pre-set room temperature by sending a signal to the heating/cooling device (contact opening) when the pre- set room temperature has been reached. After receiving such a signal, the heating/cooling device is disabled (if it is connected to a CH boiler controller, the CH boiler switches to sustain mode after receiving the signal).
If the regulator is used in heating mode, it may also cooperate with a floor sensor. In such a situation, the contact remains closed when the floor temperature is below the minimum threshold. After the threshold temperature has been exceeded, the contact remains closed until the pre-set room temperature is reached. If the floor sensor temperature exceeds the maximum value, the controller will open the contact regardless of the current room temperature.

NOTE
In order for the floor heating functions to be available in the controller menu, an additional sensor must be connected to the floor sensor contact.

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 (comfort temperature and economical temperature) as well as define the exact time of entering day mode and night mode.
In order to activate this mode, press EXIT button until day/night mode icon appears on the main screen.

Weekly control
This mode enables the user to define the time when the pre-set comfort temperature and the pre-set economical temperature will apply. The user may set 9 different programs divided into three groups:

• PROGRAMS 1÷3 – daily temperature values are set for all days of the week;
• PROGRAMS 4÷6 – daily temperature values are set separately for the weekdays (Monday-Friday) and for the weekend (Saturday-Sunday);
• PROGRAMS 7÷9 – daily temperature values are set for each day of the week separately.

The display shows the hours when the comfort temperature applies. In the remaining time period economical temperature applies.
In order to activate this mode, press EXIT until a weekly control icon appears on the main screen.

• 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 automatically when one of these buttons is pressed. Once the manual mode is activated, the previous operation mode enters sleep mode until the next pre-programmed temperature change. Manual mode may be deactivated by pressing EXIT button.

Example 1 – manual mode activation in Day/night mode
When Day/night mode is active, the user changes the pre-set temperature by pressing one of the buttons which automatically activates manual mode. The controller returns to Day/night mode when daytime changes into nighttime (or the other way round) or when the user presses EXIT.

Example 2 – manual mode activation in weekly control mode
When Weekly control is active, the user changes the pre-set temperature by pressing one of the buttons which automatically activates manual mode. The controller returns to weekly control mode when, according to the weekly schedule, economical temperature changes into comfort temperature (or the other way round) or when the user presses EXIT.
