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.

TECHNICAL DATA

Power supply	2xAA 1.5V batteries – Alkaline
Operating frequency	868MHz
Locking ring	M30x1,5
Dimensions	A – 48,6 B – 82,7 C – 47,6 mm

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 – after 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.

REGISTRATION

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.

Use the tool included in the kit to register.

REPLACING THE BATTERY

Remove the cover

Remove the batteries
Press the communication button in order to release the residual electricity
Insert new batteries

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

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.

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.

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

Errors in the operation of the EU-G-X actuator will be displayed on the main controller.

Error	Description	Possible causes
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.
#1	Calibration error 1 Bolt retraction to mounting position took too long.	Locked/damaged actuator piston. Check the assembly and recalibrate the actuator.
#2	Calibration error 2 Bolt maximally extended as it did not meet any resistance during extension.	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.
#3	Calibration error 3 Bolt extension too short. The bolt met resistance too early during the calibration process.	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.
#4	Actuator feedback communication error. No communication with the actuator for an hour is considered an error. The actuator is then set to 10% open The error will reset after a data package is received.	master controller disabled poor signal or no signal originating from the master controller defective RC module in the actuator
#5	Battery low The actuator will detect battery replacement after voltage rises and launch calibration	battery depleted
#7	Actuator blocked	while changing the opening of the valve, excessive load was encountered Recalibrate the actuator.
