Tech Controllers EU-294 v2 User Manual page 2

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 EU-290 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
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
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

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
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.
of pre-set
In order to define the hysteresis value, press
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.
