Sterowniki Two State with Traditional Communication User Manual

Safety

Before using the device for the first time the user should read the following regulations carefully. Not obeying the rules included in this manual may lead to personal injuries or controller damage. The user’s manual should be stored in a safe place for further reference. In order to avoid accidents and errors it should be ensured that every person using the device has familiarized themselves with the principle of operation as well as security functions of the controller. If the device is to be sold or put in a different place, make sure that the user’s manual is there with the device so that any potential user has access to essential information about the device.
The manufacturer does not accept responsibility for any injuries or damage resulting from negligence; therefore, users are obliged to take the necessary safety measures listed in this manual to protect their lives and property.

WARNING

• High voltage! Make sure the regulator is disconnected from the mains before performing any activities involving the power supply (plugging cables, installing the device  etc.)
• The device should be installed by a qualified electrician.
• Before starting the controller, the user shoud measure earthing resistance of the electric motors as well as the insulation resistance of the cables.
• The regulator should not be operated by children.

Description

EU-294 room regulator is intended for controlling the heating or cooling device (e.g. gas, oil or electric furnace or the CH boiler controller).
Its main task is to maintain the pre-set temperature in the flat by sending a signal to the heating/cooling device (contact opening) when the desired temperature is reached.
EU-294 v1 has a built-in voltage-free contact and it communicates with the heating device via a wire. EU-294 v2 uses radio signal to send the open/close request to EU-290  M1 module which is connected to the heating device.

Installation

The controller should be installed by a qualified person.
WARNING
Risk of fatal electric shock from touching live connections. Before working on the controller switch off the power supply and prevent it from being accidentally switched on.
WARNING
Incorrect connection of the wires may damage the controller!

Remove the mounting base. Take out the terminal block:

Connect the wire to the terminal block. Insert the terminal block into the regulator.

EU-294v2 room regulator is sold in a set including M1 wireless module:

1. Green control light 1 – indicates data reception, goes on during channel change;
2. Red control light – indicates receiver operation;
3. Green control light 2 – goes on when the room temperature fails to reach the pre-set temperature – the heating device is switched on.
4. Channel change button

How to change communication channel

It is necessary to select the same communication channel in the room regulator and EU-290 M1 wireless module. Channel “35” is the default communication channel in both  devices. It may be easily changed (if the current channel is used by other devices). To change the channel, follow these steps:
STEP 1
Press and hold the channel change button on EU-290 M1 wireless module (found under the cover) until the green control light 1 goes on.
STEP 2
Press the channel change button on the room regulator (found on the back side of the regulator).
STEP 3
Use PLUS and MINUS button to select desired communication channel.
When the number stops flashing (about 3 seconds after the last change), the change has been confirmed. The green control light in EU-290 M1 should go off indicating that  the channel change process has been successful

Description of the functions available in the menu:
To enter the controller menu, press and hold PLUS and MINUS buttons.
These buttons can be used to switch between menu options.

1. Select operation mode
   ‚OUT’ function enables the user to choose the regulator operation mode between heating (‚HEA’) and cooling (‚Coo’). After selecting the ‚OUT’ function, the screen  flashes for 3 seconds and then shows the operation modes available: (Coo, HEA). Use PLUS or MINUS to select the mode. Wait 3 seconds to confirm. Next, the display shows a temperature setting screen, enabling the user to adjust the temperature using PLUS and MINUS buttons. Wait 3 seconds to confirm.
   NOTE
   This option is available only in the case of the ST-294v1 regulator.

2. T1/T2 Min/max parameters of pre-set temperature
   This function enables the user to set the minimum T1 and the maximum T2 value of the pre-set temperature. After selecting this function, the screen flashes for 3  seconds. Use PLUS and MINUS buttons to select desired value. It will be confirmed automatically after 3 seconds.

3. Auto-lock
   ‚Loc’ function enables the user to activate the key lock. After selecting this function, the screen flashes for 3 seconds. Next, the user is asked if they want to activate the  key lock (yes/no). Select the answer using PLUS and MINUS button. Wait 2 seconds to confirm. When the lock is active, the keys are locked after 10 seconds of  inactivity. To unlock, press and hold PLUS and MINUS buttons. ‚Ulc’ message informs that the keys have been unlocked.

4. Software version
   This option enables the user to view current software version.

5. Factory settings
   ‚Def’ function enables the user to restore factory settings. After selecting this function, the screen flashes for 3 seconds. Next, the user is asked if they want to restore  factory settings (yes/no). Select the answer using PLUS and MINUS button. Wait 3 seconds to confirm.

6. Exit the menu
   After selecting ‚Ret’ option, the screen flashes for 2 seconds and exits the menu.

7. Hysteresis
   Hysteresis defines the pre-set temperature tolerance in order to prevent undesired oscillation in case of small temperature fluctuation within the range of 0,2 ÷ 4°C.
   Example:
   Pre-set temperature: 23°C Hysteresis: 1°C
   The room temperature is considered too low when it drops to 22°C.
   In order to define the hysteresis value, press PLUS and MINUS simultaneously and hold it for about 1 minute. Use the buttons to set desired value. When the temperature stops flashing (about 3 seconds after the last change), the change has been confirmed.

8. Battery
   ‚Bat’ function enables the user to monitor the battery level (%). After selecting this option, the screen flashes for 3 seconds. Next, it displays the battery level given in percent.

9. Calibration
   ‚Cal’ function enables the user to calibrate the sensor within the range of -10°C to +10°C. After selecting this option, the screen flashes for 3 seconds. Next, it displays  calibration setting. Use PLUS and MINUS to edit the value.
