Function and device overview

The Homematic IP Radiator Thermostat enables you to regulate the room temperature in your smart home based on the time of day using the Homematic IP smartphone app and to adjust the temperature to your requirements. Customised temperature schedules are easy to create using an app – with up to 3 adjustable heating schedules and 13 changes a day. Alternatively, you can set the temperature directly on the device fully intuitively. With the additional boost function, cool rooms can be heated within short by opening the heating valve. The rotatable display and the contemporary housing design mean that the radiator thermostat fits perfectly into your home environment. Any open windows and doors are detected via an open-window-detection function or even more precisely in combination with a Homematic IP Door / Window Contact. Heating temperatures are automatically lowered so that no energy is wasted. Once the windows are closed, the temperature set for your comfort will be reached again straight away.
The radiator thermostat fits to all common radiator valves and is easy to mount – without having to drain any water or intervene in the heating system.

Installation
Please read this entire section before starting the installation.

The Homematic IP Radiator Thermostat is easy to install, and can be installed 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 mm from the most popular manufacturers.
An overview and information about compatible manufacturers and valve adapters can be found at www.homematic-ip.com

Using the adapters supplied, the device can also be installed on radiator valves of type Danfoss RA, Danfoss RAV and Danfoss RAVL, (see „6.2.4 Adapter for Danfoss).

Removing a thermostat
In case of visible damage to the existing radiator, 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 thermostat 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 fitting: 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.
• Tighten the metal nut on the heating valve.

To make installation easier, you can take the batteries out of the battery compartment (C) and press and hold the button in the battery compartment while you are tightening the metal nut on the heating valve. Pressing this button blocks the rotating mechanism in the radiator thermostat, making it easier to move the display to your chosen position.

If required, you can use one of the supplied adapters for Danfoss valves, (see „6.2.4 Adapter for Danfoss), 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.

Adapter for Danfoss
One of the adapters supplied is required to attach to Danfoss valves. The assignment of the suitable adapter to the relevant valve is shown in the following illustrations.

Please be careful not to trap your fingers between the two halves of the adapter!
The RA and RAV adapters have been manufactured with pre-tension for a better fit. Use a screwdriver during installation if necessary, and bend it open slightly in the vicinity of the screw.

Danfoss RA
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.

• Snap the adapter completely onto the valve.
• Secure the adapter with the enclosed screw and nut.

The RAVL adapter does not need to be screwed on.

Adjustment run

When the batteries are inserted, the motor retracts to simplify installation. Meanwhile, “ ” and the activity symbol ( ) are displayed.

If the adjustment run was initiated prior to installation, or if an error message (F1, F2, F3) is displayed, press the system button (D): the motor will reverse to the “ ” position. The adjustment run can then
be restarted.

After the radiator thermostat has been mounted successfully, an adjustment run ( ) must be performed to adjust the device to the valve. To do this, proceed as follows:

• When “ ” is shown in the display, press the system button (D) to start the adjustment run.

If the display backlight is off, you must press button (D) a second time to start the adjustment run.

The radiator thermostat performs the adjustment run, During this time,“ ” and the activity symbol ( ) will be displayed. During this time, no other operation is possible. After the adjustment run has been successful, the display returns to normal. The radiator thermostat can now be operated.

Operation

After configuration, simple operations are available directly on the device.

If the radiator thermostat is in standby mode, please press the system button (D) once before operation to activate the device.

• Temperature: Gently rotate the temperature regulator (E) clockwise or anticlockwise to adjust the temperature of the radiator. In automatic mode, the manually set temperature will remain the same until the next point at which the schedule changes. The heating schedule set via the app will then be reactivated. During manual mode, the temperature remains activated until the next manual change.
• Boost function: Briefly press the system button (D) to activate the boost function and heat up the radiator quickly and briefly by opening the valve. There will be a pleasant room temperature right away because of the radiated heat.
• Changing the display orientation: Press the system button (D) and at the same time rotate the temperature regulator (E) in the direction the display is to turn in. The display rotates 180°.

The operating lock of the radiator thermostat can be activated and deactivated via the Homematic IP app. Tap on the menu symbol in the top left of the screen of your app and select the menu item “Device overview”. Select the respective radiator thermostat to switch the operating lock “ON” or “OFF”.

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 replace the radiator thermostat bat-teries, please proceed as follows:

• Open the battery compartment (C) by sliding the battery compartment cover (C) downwards (see figure).
• Remove the used batteries.
• Insert two new 1.5 V LR6/Mignon/AA batteries into the battery com-partment, making sure that you insert them the right way round.
• Slide the battery compartment cover (C) back up (see figure).

Once the batteries have been inserted, the radiator thermostat will perform a self-test for approx. 2 seconds. After this, the device performs an initialisation ( ) and a test display (orange and green lights).
Once the batteries have been inserted, the radiator thermostat will perform a self-test for approx. 2 seconds. After this, the device performs an initialisation ( ) and a test display (orange and green lights).

• Start the adjustment run ( ) again by briefly pressing the system button (D).

Caution! Avoid skin and eye contact when handling leaking batteries. Wear suitable protective gloves when removing leaking batteries and residues from a device. Rinse with plenty of water in the event of skin contact.

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 „6.1 Pairing). In this case, replace the empty batteries with two new ones (see „8 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 inter-ference, (see „1 Package contents). This may be caused by the following:

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

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 startup 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

securely
F3| Adjustment range too small| Please check whether the valve pin is stuck.
Short orange flashes| Radio transmission/at- tempting to transmit or configuration data being transmitted| Wait until the transmission is completed.
1x long green flash| Transmission confirmed| You can continue operation.
1x long red flash| Transmission failed or duty cycle limit reached| Please try again (see „9.2 Command not confirmed ) or (see

„9.3 Duty cycle ).

Short orange flashes (every 10 s)| Pairing mode active| Enter the last four digits of the device serial number to confirm (see „6.1 Pair- ing).
6x long red flashes| Device defective| Please see your app for error message or contact your retailer.
Brief steady orange light (after green or red confir- mation)| Batteries empty| Replace the batteries (see

„8 Changing the batteries.

Battery warning ( )| Battery voltage low| Replace the device batter- ies (see „8 Changing the batteries).
Battery warning ( ) and —| Valve moved to error po- sition| Replace the device batter- ies (see „8 Changing the batteries).
If empty batteries are not replaced, the radiator thermostat moves to a “valve er- ror position”. This avoids a situation where the set temperature in the room can- not be reached any more due to a low battery. A valve error position of 15% is set in the factory settings.
1x orange and 1x green light (after inserting batteries)| Test display| You can continue once the test display has stopped.
---|---|---
Alternating long and short orange flashing| Software update (OTAU)| Wait until the update is completed.

• Release the system button.
• Press and hold the system button again for 4 seconds, until the LED lights up green.
• Release the system button to finish restoring the factory settings.

The device will perform a restart.

Maintenance and cleaning

The device does not require you to carry out any maintenance other than replacing the battery when necessary. Leave any maintenance or repair to a specialist.

Clean the device using a soft, clean, dry and lint-free cloth. You may dampen the cloth a little with lukewarm water to remove more stubborn marks. 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 Str. 29, 26789 Leer, Germany, hereby declares that the radio equipment types Homemat-ic IP HmIP-eTRV-E, HmIP-eTRV-E-S and HmIP- eTRV-E-A are 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
