Frequently Asked Questions - HmIPeTRVBUK Homematic IP

How to install the Homematic IP wall thermostat?

To install the thermostat, first choose a suitable location (smooth, clean wall). Attach the wall mount: either with the supplied double-sided adhesive tapes (on a flat surface) or with screws and dowels (drilling with 60 mm spacing). Then insert the electronic module into the mount until it snaps into place. Ensure the batteries are inserted with correct polarity before fixing.

How to replace the thermostat batteries?

When the empty battery symbol appears, remove the electronic module from the wall mount by grasping it from the sides. Turn it over, remove the used batteries and insert two new 1.5 V LR6/Mignon/AA batteries, observing polarity (+/-). Reattach the module to the mount. After insertion, the LED performs a self-test (orange then green light).

What to do if the display shows the empty battery symbol?

The empty battery symbol indicates low batteries. Replace them with two new batteries of the same type (1.5 V LR6/Mignon/AA). If the voltage is still sufficient, the device may temporarily operate, but it is advisable to change the batteries quickly to avoid loss of communication. Refer to the Battery Replacement section of the manual.

How to switch to manual mode?

Press and hold the Menu button (approx. 2 seconds) to open the configuration menu. Use the + or - buttons to select the MANU symbol, then confirm with the Menu button. The symbol flashes twice and the device switches to manual mode. You can then set the desired temperature with the +/- buttons.

How to program a heating profile?

Access the configuration menu (long press on Menu), select the Prg symbol and confirm. Choose the days (week, weekend, all days, etc.). Set the start time (default 00:00) and desired temperature for each period. You can define up to 6 heating phases and 13 switching times. Confirm each step with the Menu button.

How to activate vacation mode?

In the configuration menu (long press on Menu), select the Vacation symbol and confirm. Enter the end time and date of the vacation, then the desired set temperature during absence. Confirm each entry with Menu. The vacation mode symbol is displayed on the screen until the end date.

What does the orange flashing LED mean?

A short orange flash (every 10 seconds) indicates that teaching-in mode is active. In this mode, the device can be taught-in to another Homematic IP device or to the Access Point. For direct teaching-in, press the system button for 4 seconds. If the LED flashes orange without teaching-in, wait for the 3-minute timeout.

How to reset the device to factory settings?

Remove the electronic module from the wall mount. Remove one battery. While reinserting the battery, press and hold the system button for about 4 seconds until the LED flashes orange rapidly. Release, then press the system button again for 4 seconds until the LED lights up green. Release to complete the reset.

What is the radio range of the thermostat?

The radio range in open field is typically 250 meters. Indoors, the range may be reduced due to obstacles (walls, furniture, etc.). Transmission uses the 868 MHz frequency band with a maximum power of 10 dBm. For reliable communication, maintain a minimum distance of 50 cm between devices during teaching-in.

Can I use the thermostat without a Homematic IP Access Point?

Yes, the wall thermostat can operate in standalone mode without an Access Point. In this case, you can use manual, automatic and vacation modes directly via the screen and buttons. Direct teaching-in with a heating actuator or radiator thermostat is possible without an Access Point. However, to benefit from all features (remote programming, scenarios, notifications), it is recommended to use a Homematic IP Access Point or a CCU3.

Illustration of hands installing a battery pack into an open panel (no text or symbols visible)

Figure 16

• Place the electronic unit back into the mounting plate ( see figure).
• Please pay attention to the flashing signals of the device LED while inserting the batteries (see „10.4 Error codes and flashing sequences“ on page 37).

Once the batteries have been inserted, the device will perform a self-test (approx. 2 seconds). Afterwards, initialisation is carried out. The test display will indicate that initialisation is complete: orange and green lighting.

10 Troubleshooting

10.1 Low battery

Provided that the voltage value permits it, the wall 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 "10.4 Error codes and flashing sequences" on page 37). In this case, replace the empty batteries by two new batteries (see "9 Replacing batteries" on page 35).

10.2 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 „13 General information about radio operation“ on page 39).

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.

10.3 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 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).

13 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.

eQ-3 AG, Maiburger Straße 29, 26789 Leer, Germany hereby declares that the radio equipment type Homematic IP HmIP-WTH-B-2, HmIP-WTH-B-A is compliant with Directive 2014/53/EU. The full text of the EU declaration of conformity is available at the following internet address:
