Product Usage Instructions
Installation
-
Measure the thread diameter and pin height of the radiator
valve. -
Choose the valve head based on the thread diameter (M30 or M28)
and pin height (30mm for M30 or 28mm for M28). -
Remove the cover of the valve head.
-
Insert the batteries with correct polarity.
-
Reattach the cover.
-
Wait for the LED to indicate the software version (e.g., v3.5
flashes 3 times green and 5 times red). -
If installing on a Danfoss RA valve, use an M30 thread adapter
and screw the valve head onto the radiator valve. -
To start the adaptation process, press the button once or wait
for 3 minutes for automatic adaptation.
Synchronization with Head
An internet gateway is not mandatory for synchronization. Ensure
the head is installed and adapted to the valve insert. If connected
to a wireless control box or relay module, synchronization cannot
be activated.
FAQ (Frequently Asked Questions)
Q: What should I do if an adaptation error occurs during
installation?
A: If an adaptation error occurs with the valve insert, the LED
will flash alternately green/red every 3 seconds. Check if the
valve head is properly installed. You can retry the adaptation by
pressing the button once.
Q: Is an internet gateway required for synchronization with the
head?
A: An internet gateway is not mandatory for synchronization.
Ensure that the head is correctly installed and adapted to the
valve insert.

Introduction
The wireless valve head is used for controlling radiator heating. It is an
excellent replacement for a traditional manual thermostatic valve head. For it
to function properly, pairing with a master controller is necessary. Up to six
wireless valve heads can be paired with a single controller within the same
room. Two-way communication between the devices occurs every few minutes via
radio signals. Based on the collected data, the controller modulates the valve
head’s opening. The temperature measured by the controller ensures even
heating throughout the entire room. By using an internet gateway, the set
(valve head + controller) can be controlled via the ENGO Smart application.

The installation on a Danfoss RA valve
When installing the valve head on
a Danfoss RA valve (see diagram
nearby), you must use an M30
thread adapter.
7
Screw the valve head onto the radiator valve.
INFORMATION:
If installing the valve head on a Danfoss RA valve, please contact customer
support.
ATTENTION:

To start the adaptation process press the button once once or wait 3 minutes,
then the adaptation will start automatically. When the adaptation is correct –
the LED will turn off.
If an adaptation error occurs with the valve insert, the LED will flash alternately green/red every 3 seconds. Check if the valve head is properly installed. You can immediately retry the adaptation by pressing the button once.
Synchronization with head
An internet gateway is not mandatory to synchronize thermostat with head. Make sure head is installed and adapted to valve insert (see head manual). If thermostat is connected to a wireless control box or relay module, synchronization with head cannot be activated.

Adaptation of the head with a valve insert.
The head is adapted with a valve insert, but is not paired with the
thermostat. After clicking the button 1x, the LED will flash red slowly 10x.
The head is in synchronization mode with the controller. To enter the head-to-
regulator pairing mode, press and hold the button until the LED starts
flashing blue,
then release the button.
After synchronizing the head with the controller, the LED in the head will
light up for 10 seconds.
