Tech Controllers EU-G-X User Manual page 2

DESCRIPTION
The EU-G-X device is a modern wireless thermostatic actuator designed
for installation on radiator valves. It allows for convenient and effective
temperature control in individual heating zones within the building.
The actuator control system allows for optimal thermal comfort and
promotes significant energy savings. This type of actuator can operate
with both heating and cooling systems. The device is compatible with
controllers equipped with wireless communication, e.g. Sinum, EU-L-4
WiFi, EU-L-8e, EU-L-9r, EU-WiFi 8s, etc. control units.

INSTALLING THE CONTROLLER
AND FIRST CALIBRATION
Follow these steps while installing the device:
1. Before starting the device - check that the radiator valve is not
damaged (stuck, etc.). Use a hard tool to push the valve plunger at the
radiator several times. If it does not move - replace the valve. If it works
- the device can be installed. If the valve is not checked before hand and
it has failed to properly operate, the Tech Sterowniki company will not
guarantee the correct operation of the device.
2. Installing the battery and preparing for calibration - after
inserting the battery, the actuator will start adopting the assembly
position, which will facilitate screwing the device on the valve. Once the
actuator is in the assembly position, it will keep this for 30 minutes. After
this time, the calibration will start automatically.
3. Screwing the actuator onto the radiator valve and calibration
- po przykręceniu siłownika do zaworu, aby rozpocząć ręcznie kalibrację,
naafter screwing the actuator onto the valve, to start manual calibration,
hold the communication button with the included instrument for 3
flashes of the LED.
The LED flashes 2 times - the calibration process was carried
out correctly.
The actuator can be mounted with any valve. If installed with a Danfoss
valve, use the appropriate adapter according to the diagram below.
1
Error
After the correct first calibration of the head on the valve, any subsequent error during normal operation (except for error #4)
can be corrected by corrective calibration (please refer to the section Additional functions - Corrective calibration).
Please wait 30 min. first, as the error may disappear during this time, and the actuator will resume correct operation.
Calibration error 1
#1
Bolt retraction to mounting position took too long.
Calibration error 2
Bolt maximally extended as it did not meet any resistance
#2
during extension.
Calibration error 3
Bolt extension too short. The bolt met resistance too early
#3
during the calibration process.
Actuator feedback communication error.
No communication with the actuator for an hour is considered
#4
an error. The actuator is then set to 10% open
The error will reset after a data package is received.
Battery low
The actuator will detect battery replacement after voltage

Errors in the operation of the EU-G-X actuator will be displayed on the main controller.
Description
To register the actuator in a specific zone, select the option to register
in the main controller (please refer to its instruction manual), and then
briefly press the communication button.
After releasing the button, observe the indicator LED:
- if the LED flashes red 2 times - the registration process was carried
out correctly
- if the LED flashes red 1 time - press the registration button on the
head again
- if the LED is lit red - registration error - the registration must be
repeated
NOTE
Registration is possible while in the mounting position before
installing the valve or after calibrating the actuator on the valve.
C
Communication
Use the tool included in the kit to register.
REPLACING THE BATTERY
1. Remove the cover
2. Remove the batteries
3. Press the communication button in order to release
the residual electricity
4. Insert new batteries
5.The actuator will return to the assembly position.
Subsequently, calibrate or wait 30 minutes (See:
Installing the Controller and Calibrating items 2 and 3).
CAUTION
If the actuator indicates a battery level of 0 or 1% in the master
controller (depending on the type of master controller), be prepared to
replace the battery.
Always use two new batteries of the same brand. If two different
batteries are installed or ones with different charge levels, the Tech
Sterowniki company does not guarantee the correct operation of the
actuator.
ADDITIONAL FUNCTIONS
1. Connectivity test
In order to check the connection with the main controller, press the
communication button and hold it until the control light fl ashes twice.
Release the button and observe the control light:
- if the LED flashes red 2 times - it indicates successful communication
- if the LED is lit red - there is no connection with the main
controller.
Connectivity test enables the user to identify the controller and the zone
in which a given actuator is registered. The main controller displays
appropriate message.
1. RECALIBRATION
It is possible to manually initiate recalibration. To do this, hold the
communication button for 3 flashes of the LED. During this calibration,
the actuator will not stop in the mounting position - the actuator
therefore must be mounted on the radiator valve.
2.CORRECTIVE CALIBRATION
In the event of an error at the actuator, it enters the corrective
calibration. The actuator may perform 3 such tests. After successful
calibration, this error will disappear.
The calibration can be interrupted by holding the registration button
down for 3 subsequent LED flashes. The exit from the corrective
calibration will be then signalled by a longer LED flash. After this, manual
calibration can be called up.
If the corrective calibration does not remove the error, attempt should be
made to perform it manually (Recalibration) by holding the registration
button down for 3 subsequent LED flashes or by removing the batteries.
After removing the batteries and holding the registration button, the
actuator will return to its factory setting.
NOTE
If the errors persist, try replacing the batteries with new ones, as they
can already be discharged. See: Replacing the battery.
ALARMS
• Locked/damaged actuator piston. Check the assembly and
recalibrate the actuator.
• actuator was not screwed properly onto the valve
• the actuator was not fully tightened onto the valve
• actuator movement was excessive, or non-standard valve
encountered
• motor load measurement failure occurred
Check the assembly and recalibrate the actuator.
• valve movement was too small, or a non-standard valve
encountered
• motor load measurement failure
• motor load measurement inaccurate due to low battery charge
Check the assembly and recalibrate the actuator.
• master controller disabled
• poor signal or no signal originating from the master controller
• defective RC module in the actuator
• battery depleted
• while changing the opening of the valve, excessive load was
encountered
Recalibrate the actuator.
