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, among others, mounting strips and other controllers with wireless communication.
OPERATING PRINCIPLE
The actuator sends RC data to the controller every few minutes. On the basis
of this data, the controller adjusts the opening of the actuator. The actuator
will not change the opening until it receives further data from the
controller.
It is possible to manually force communication. To do this, hold the
communication button for 2 flashes of the LED. The next 2 flashes indicate
successful communication, while 1 denotes a communication error.
After a successful communication process, the actuator sends the data to the
controller, in which it informs that this action has been forced by the user.
As a result of manually forcing the communication, a screen will be displayed
on the controller with information in which zone the actuator is registered,
as well as additional diagnostic information.
NOTE After each battery replacement, reset the actuator by holding the communication button for 3 seconds (reset does not un-register the actuator from the master controller).
CALIBRATION
The actuator calibration takes place before the start of operation of the device, as well as cyclically during its operation.
Initial calibration process:
- To perform the initial calibration process, remove the batteries, press the communication button several times and reinsert the batteries.
- Bolt retraction – after inserting the battery into the actuator, the screw is retracted backwards as much as possible, and the actuator adopts the mounting position.
- Mounting position – the actuator remains in this position for approx. 30 minutes so that the user has the opportunity to register and install the actuator on the heater. Holding the button for 3 flashes of the LED will cancel the mounting position and continue the calibration.
- Maximum bolt extension – the actuator extends the bolt until resistance is encountered on the valve. Resistance is detected as an increase in the current above the preset threshold. After the maximum extension, the actuator records the valve stroke and reduces it by the set margins so that during operation it never positions the bolt too close to the minimum or maximum extension. Based on the saved stroke, it will convert the percentage of valve opening sent from the controller to the appropriate position.
The LED flashes 2 times – the calibration process was carried out
correctly.
During operation, the actuator gradually decalibrates, which is why this
device is equipped with an adaptation function every 50 shifts.
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 signaled by a longer LED flash. After this, manual calibration can be
called up.
If the corrective calibration does not remove the error, an attempt should be
made to perform it manually 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. If the errors persist, try replacing the batteries with new
ones, as they can already be discharged.
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.
INSTALLATION
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:
- the LED flashes 2 times – the registration process was carried out correctly.
- the LED is lit continuously for 2 seconds – registration error – the operation must be repeated.
NOTE Registration is possible while in the mounting position before installing the valve or after calibrating the actuator on the valve.
ALARMS
Errors in the operation of the EU-G-X actuator will be displayed on the main controller.
| Error | Description | Possible causes |
|---|
After correct calibration of the head on the valve, any subsequent error (except error #4) during normal operation may be removed by calibration.
Please wait 30 mins, as the error may disappear during this time and the actuator can 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.
For the last x minutes, the actuator did not receive a data package via wireless communication.
After this error is triggered, the actuator will set itself to 0% opening.
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.
