Installation
Please read this entire section before starting the installation.

The Homematic IP Radiator Thermostat is easy to install and can be done without draining heating water or intervening in the heating system. No special tools are required, nor does the heating have to be switched off. The union nut (A) attached to the radiator thermostat can be used universally and without accessories for all valves with a thread size of M30 x 1.5 mm from the most popular manufacturers, such as:

• Heimeier
• MNG
• Junkers
• Landis&Gyr (Duodyr)
• Honeywell-Braukmann
• Oventrop
• Schlösser
• Comap
• Valf Sanayii
• Mertik Maxitrol
• Watts
• Wingenroth (Wiroflex)
• R.B.M
• Tiemme
• Jaga
• Siemens
• Idmar

The device can also be installed on type Danfoss RA (Danfoss RA adapter“) radiator valves using the enclosed adapter.

Removing a thermostat
In case of visible damage to the existing thermostat, valve, or heating pipes, please consult a specialist.

• Remove the old thermostatic head from your radiator valve:
• Rotate the thermostatic head anticlockwise to the maximum value (1). The thermostatic head then no longer presses against the valve spindle, making it easier to remove.

The thermostatic head may be held in place in various ways:

• Union nut: Unscrew the union nut in an anticlockwise direction (2). The thermostatic head can then be removed (3).
• Snap-on fastenings: Thermostatic heads that are fastened this way can be detached by turning the fastener/union nut anticlockwise a little. The thermostatic head can then be removed.
• Compression fittings: The thermostatic head is held in place by a mounting ring, which is held together with a screw. Loosen this screw and remove the thermostatic head from the valve.
• Threaded connection with set screw: Loosen the set screw and remove the thermostatic head.

Mounting the radiator thermostat
After removing the old thermostatic head, you can mount the new radiator thermostat on the heating valve:

• Place the radiator thermostat with the metal nut (A) on the heating valve.

If required, you can use one of the supplied adapters for Danfoss valves,  or the supplied support ring.

 Support ring
With some manufacturers’ valves, the part of the valve that protrudes into the device has only a small diameter, which causes the radiator thermostat to sit more loosely on the valve. In this case, the provided support ring should be placed into the flange before installing the radiator thermostat. You can then mount the radiator thermostat again as described above. Figure 6Danfoss RA adapter
The provided adapter is required to attach to Danfoss RA valves. The RA adapter has been manufactured with pre-tension to provide better fit. Use a screwdriver during installation if necessary and bend the adapter open slightly in the vicinity of the screw.
Figure 7

Danfoss valve bodies have elongated notches around their circumference, which also ensure that the adapter is properly seated when it snaps on.

• During installation, please ensure that the pins inside the adapter are lined up with the notches on the valve.
• Please be careful not to trap your fingers between the two halves of the adapter!

After clipping onto the valve body, please attach the adapter using the provided screw and nut.

Changing the batteries

If the symbol for empty batteries ( ) appears in the display or in the app, please replace the used batteries with two new LR6/Mignon/AA batteries. You must observe the correct battery polarity. To insert new batteries, proceed as follows:

• Open the battery compartment (B) by pulling the battery compartment cover downwards ( see figure).
• Remove the batteries.
• Insert two new 1.5 V LR6/Mignon/AA batteries into the battery compartment, making sure that you insert them the right way round.

• After inserting the batteries, pay attention to the flashing sequences of the LED see „10.4 Error codes and flashing sequences.

Once the batteries have been inserted, the radiator thermostat will perform a self-test and an adjustment run, if required (approx. 2 seconds). Afterwards, initialization is carried out. The LED test display will indicate that initialisation is complete by lighting up orange and green.

 Troubleshooting

 Weak batteries
Provided that the voltage value permits it, the radiator thermostat will remain ready for operation even if the battery voltage is low. Depending on the par-ticular load, it may be possible to send transmissions again repeatedly once the batteries have been allowed a brief recovery period.
If the voltage drops too far during transmission, the empty battery symbol ( ) and the corresponding error code will be displayed on the device, (see „10.4 Error codes and flashing sequences “ on page 37). In this case, replace the empty batteries with two new ones  Changing the batteries
Command not confirmed
If at least one receiver does not confirm a command, the LED (D) lights up red at the end of the failed transmission process. The reason for the failed transmission may be radio interference, (see „13 General information about radio operation“ on page 39). This may be caused by the following:

• The receiver cannot be reached.
• The receiver is unable to execute the command (load failure, mechanical blockade, etc.).
• The receiver is faulty.

Duty cycle
The duty cycle is a legally regulated limit of the transmission time of de-vices in the 868 MHz range. The aim of this regulation is to safeguard the operation of all devices working in the 868 MHz range.
In the 868 MHz frequency range we use, the maximum transmission time of any device is 1% of an hour (i.e. 36 sec-onds in an hour). Devices must cease transmission when they reach the 1% limit until this time restriction comes to an end. Homematic IP devices are designed and produced with 100% conformity to this regulation. During normal operation, the duty cycle is not usually reached. However, repeated and radio-intensive pairing processes mean that it may be reached in isolated instances during the start-up or initial installation of a system. If the duty cycle is exceeded, this is indicated by three slow flashes of the device LED and may manifest itself in the device temporarily working incorrectly. The device starts working correctly again after a short period (max. 1 hour).

Error codes and flashing sequences

Do not use any detergents containing solvents, as they could corrode the plastic housing and label.

General information about radio operation

Radio transmission is performed on a non-exclusive transmission path, which means that there is a possibility of interference occurring. Interference can also be caused by switching operations, electrical motors or defective electrical devices.The transmission range within buildings can differ significantly from that available in open space. Besides the transmitting power and the reception characteristics of the receiver, environmental factors such as humidity in the vicinity play an important role, as do on-site structural/screening conditions. eQ-3 AG, Maiburger Strasse 29, 26789 Leer, Germany, hereby declare that the radio equipment type Homematic IP HmIP-eTRV-B-2 is compliant with Directive 2014/53/EU. The full text of the EU declaration of conformity is available at the following internet address:www.homematic-ip.com
