5.2 Mounting

Please read this entire section before starting to mount the device.

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 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

By means of the adapter in the delivery, the device can be installed also on radiator valves of type Danfoss RA (see see „5.1.1 Direct pairing with a Homematic IP device“ on page 37).

5.2.1 Mounting the radiator thermostat

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

Remove the old thermostat dial from your radiator valve.

- Rotate the thermostat dial to the maximum value (1) anticlockwise (see figure 6). The thermostat dial then no longer presses against the valve spigot, making it easier to remove.

There are different ways of fixing the position of the thermostat dial:

- Union nut: Unscrew the union nut in an anticlockwise direction (2). The thermostat head can then be removed (3).

- Snap-on fastenings: Thermostat dials that have been attached using this method can be easily released by giving the lock/union nut a slight turn in the anticlockwise direction (2). The thermostat head can then be removed (3).

- Compression fitting: The thermostat dial is held in place by a mounting ring which is held together with a screw. Loosen this screw and remove the thermostat head from the valve (3).

- Threaded connection with set screw: Loosen the set screw and remove the thermostat head (3).

After removing the old thermostat dial you can mount the Homematic IP Radiator Thermostat with the union nut (A) to the radiator valve (see figure 7).

If required, you can use the supplied adapter for Danfoss RA valves (see see „5.1.1 Direct pairing with a Homematic IP device“ on page 37) or the supplied support ring (see see „5.2.3 Support ring“ on page 42).

5.2.2 Danfoss RA adapter

The provided adapter is required to attach to Danfoss RA valves. The RA-Adapter has been manufactured with pre-tension in order to provide better fit. Use a screwdriver during installation if necessary and bend the adapter open slightly in the vicinity of the screw (see figure 8).

The 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. Ensure that a suitable adapter for the valve is properly clipped on.

Please ensure that you do not 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.

5.2.3 Support ring

The valves from different manufacturers may have tolerance fluctuations that make the radiator thermostat more loosely seated on the valve. In this case, the provided support ring should be placed into the flange before mounting the device (see figure 9).

5.3 Adaption run

Once the batteries have been inserted, the motor reserves. Meanwhile, "InS" and the activity symbol (n) are displayed (see figure 10).

After the radiator thermostat has been mounted successfully, an adaption run (AdA) has to be performed in order to adapt the device to the valve. To do this, proceed as follows:

- As soon as "AdA" is displayed, press the menu/boost button (G) to start the adaption run (see figure 11).

Now the actuator performs an adaption run. "AdA" and the activity symbol (n) are displayed (see figure 11). During this time, no other operation is possible. After the adapting run has been successful, the display returns back to normal.

If the adapter run has been initiated prior to mounting or if an error message (F1, F2, F3) is displayed, press the menu/boost button (G) and the motor reverses to the "InS" position.

8 Replacing batteries

If the symbol for empty batteries (☐) appears in the display or in the app, please replace the used batteries by two new LR6/mignon/AA batteries. You must observe the correct battery polarity.

To insert new batteries, please proceed as follows:

• Open the battery compartment (B) by pulling the battery compartment down (see figure 3).
• 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 (see figure 12).
• Close the battery compartment.
• Please pay attention to the flashing signals of the device LED while inserting the batteries (see see „9.4 Error codes and flashing sequences“ on page 50).

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

Caution! There is a risk of explosion if the battery is not replaced correctly. Replace only with the same or equivalent type. Never recharge non-rechargeable batteries. Do not throw the batteries into a fire. Do not expose batteries to excessive heat. Do not short-circuit batteries. Doing so will present a risk of explosion.

Used batteries should not be disposed of with regular domestic waste! Instead, take them to your local battery disposal point.

9 Troubleshooting

9.1 Weak batteries

Provided that the voltage value permits it, the radiator thermostat will remain ready for operation also if the battery voltage is low. Depending on the particular 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 see „9.4 Error codes and flashing sequences“ on page 50). In this case, replace the empty batteries by two new batteries (see see „8 Replacing batteries“ on page 48).

9.2 Command not confirmed

If at least one receiver does not confirm a command, the device LED lights up red at the end of the failed transmission process. The failed transmission may be caused by radio interference (see see „12 General information about radio operation“ on page 53). The failed transmission may also be caused by the following:

• Receiver cannot be reached.
• Receiver is unable to execute the command (load failure, mechanical blockade, etc.).
• Receiver is defective.

9.3 Duty cycle

The duty cycle is a legally regulated limit of the transmission time of devices 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 seconds 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 pair processes mean that it may be reached in isolated instances during start-up or initial installation of a system. If the duty cycle is exceeded, this is indicated by one long flash of the device LED (D), and may manifest itself in the device temporarily working incorrectly. The device starts working correctly again after a short period (max. 1 hour).

9.4 Error codes and flashing sequences

Flashing code / LC display	Meaning Solution

12 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 range of transmission within buildings can differ greatly from that available in the open air. Besides the transmitting power and the reception characteristics of the receiver, environmental factors such as humidity in the vicinity have an important role to play, as do on-site structural/screening conditions.

Hereby, eQ-3 AG, Maiburger Str. 29, 26789 Leer/Germany declares that the radio equipment type Homematic IP HmIP-eTRV-B-2 is in compliance 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
