5.2 Mounting

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

The Hematic 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 metal 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 Neumeier, MNG, Junkers, Landis&Gyr (Deodar), Honeywell-Brackman, Overtrip, Schlossberg, Coma, Valve Sanayi, Metric Amitrole, Watts, WinG Enroth (Wiroflex), R.B.M, Time, Jaga, Siemens and Inmar.
By means of the adapters in the delivery, the device can also be installed on radiator valves of type Danfoss RA, Danfoss RAV and Danfoss RAVL (see „5.2.3 Adapter for Danfoss“ on page 46).
5.2.1 Mounting the radiator thermostat

**** In case of visible damage of the existing radiator, valve or heating pipes, please contact a specialist. Remove the old thermostat dial from your radiator valve. To do this, please proceed as follows:

• Rotate the thermostat dial to the maximum value (G) anti-clockwise (see figure 5). 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 (F). The thermostat head can then be removed (H).
• Snap-on fastenings: Thermostat dials that are  astened this way can be detached by turning the fastener/union nut a little bit counter-clockwise (F). The thermostat head can then be removed (H).
•  Compression fitting: The thermostat dial is held in place by a mounting ring which is held together with a screw. Loosen this  crew and remove the thermostat head from the valve (H).
•  Threaded connection with set screw: Loosen the set screw and remove the thermostat head (H). After removing the old thermostat dial you can mount the

Homematic IP Radiator Thermostat with the metal nut (A) to the radiator valve (see figure 6). If required, you can use one of the supplied adapters for Danfoss valves (see „5.2.3 Adapter for Danfoss“ on page 46) or the supplied support ring (see „5.2.2 Support ring“ on page 46).
5.2.2 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 (I) should be placed into the flange before mounting the
radiator thermostat (see figure 7).
5.2.3 Adapter for Danfoss
One of the provided adapters is required to attach to Danfoss valves. The assignment of the suitable adapter to the relevant valve can be found in the following illustrations.
Please ensure that you do not trap your fingers between the two halves of the adapter!
The RA and RAV adapters have been manufactured with pre-tension in order to provide a better seat. Use a screwdriver during installation if necessary, and bend it open slightly in the vicinity of the screw (see following figures). Danfoss RA
The Danfoss valve bodies have elongated notches (1)  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 (2) are lined up with the notches (1) on the valve. Ensure that a suitable adapter for the valve is properly clipped on.
After clipping onto the valve body, please attach the adapter using the provided screw and nut.The Danfoss valve bodies have elongated notches (1) 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 (2) are lined up with the notches (1) on the valve. Ensure that a suitable adapter for the valve is properly clipped on.
The lifter extension (3) must be fitted to the valve pin of RAV valves prior to installation. **** The Danfoss valve bodies have elongated notches (1) around their circumference, which also ensure that the adapter is properly seated when it snaps on.

1. During installation, please ensure that the pins inside the adapter (2) are lined up with the notches on the valve. Ensure that a suitable adapter for the valve is properly clipped on.

The adapter RAVL does not have to be screwed.
5.3 Adaption run
**** Once the batteries have been inserted, the motor reserves the valve pin.
After the valve pins has been reversed completely (motor no longer moves), the radiator thermostat can be moved (see figure 6). An adaption run has to be performed in order to adapt the device to the valve. To do this, please proceed as follows:

• To start the adaption run, close the battery compartment (E) using the square key (see figure 2+3).

The adaption run is alternatively started 3 minutes after reaching the valve pin end position.
Now, the radiator thermostat performs the adapting run. After the adaption run, installation is completed and the device can be individually configured and controlled.
** If the adaption run was initiated prior to installation or if it could not be fully performed, the device LED (C) lights up red up to 10 times at intervals of 10 seconds. By turning the battery compartment lock (F) using the square key (see figure 2), the motor moves back to the valve pin end position.
5.4 Mounting the disassembly protection**
If required, you can use the supplied disassembly protection to protect the radiator thermostat against theft and unauthorised disassembly. For the installation, please proceed as follows:

• Place the upper (J) and lower (K) shell above the nut or the pre-mounted radiator thermostat and allow the parts to snap into place.
  ****After engaging the upper and lower shell, the parts can no longer be separated.

 Replacing batteries

If the flashing code for empty batteries is indicated via the device LED (C) (see „7.4 Error codes and flashing sequences“ on page 56) or if the symbol for empty batteries appears in the app, replace the used batteries by two new LR6/mignon/AA batteries. You must observe the correct battery polarity.
To insert the batteries into the radiator thermostat, please proceed as follows:

• Open the lock (F) of the battery compartment (E) using the supplied four Allen head wrench (see figure 2).
• Remove the battery compartment cover (B) to the back and downwards to remove it from the device (see figure 3).
• Remove the empty 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 8).
• Re-insert the battery compartment cover and close the battery compartment using the square key.
•  Please pay attention to the flashing signals of the device LED while inserting the batteries (see „7.4 Error codes and flashing sequences“ on page 56).

Once the batteries have been inserted, the radiator thermostat will perform a self-test (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 nonrechargeable 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.
Caution! Avoid skin and eye contact with leaking batteries! Wear suitable protective gloves when removing leaking batteries and residues from a device! In case of skin contact flush with plenty of water!

Troubleshooting

7.1 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 corresponding error code will be displayed on the device (see „7.4 Error codes and flashing sequences“ on page 56). In this case, replace the empty batteries by two new batteries (see „6 Replacing batteries“ on page 52).
7.2 Command not confirmed
If at least one receiver does not confirm a command, the device LED (C) lights up red at the end of the failed transmission process. The failed transmission may be caused by radio interference (see „10 General information about radio operation“ on page 59). 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.

7.3 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 pairing 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 red flashing of the device LED (C), and may manifest itself in the device temporarily working incorrectly. The device starts working correctly again after a short period (max. 1 hour).

Maintenance and cleaning

**** The device does not require you to carry out any maintenance other than replacing the battery when necessary. Enlist the help of an expert to carry out any repairs.
Clean the device using a soft, lint-free cloth that is clean and dry. 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 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-C-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
