General system information
The eTRV is part of the Warmup konekt Wireless System. Devices in the konekt Wireless System system can be easily paired and setup through the konekt Wireless Smart Hub using the konekt App. All functions of the konekt Wireless System are described in detail in the User Guide. The User Guide and Online manuals for all other konekt Wireless devices are available on www.warmup.co.uk

Start-up

Pairing device
The eTRV can be paired seamlessly to the konekt Wireless Smart Hub (KW-UKHUB). To pair devices to the Smart Hub please download the konekt app.

Pairing to the Smart Hub

The Smart Hub must be set up via the konekt App, before any other devices can be added to your system. For further information, refer to the Smart Hub operating manual.
If you have already connected the eTRV to another konekt Wireless device, you MUST restore its factory settings first before you can connect it to the Smart Hub (see section 9)

• Step 1 – Select Pairing from the konekt App

• Step 2 – Remove insulation strip & insert batteries

Your device will automatically appear in the konekt App. To confirm, scan the QR code attached to the device or alternatively enter the last four digits of the device number (SGTIN) in the App. Give the device a name and allocate it to a room.

NOTE:

• If pairing was successful, the LED (B) will turn green. The device is now ready for use. If the LED turns red you will have to try pairing the device again.
• You can manually start pairing mode for another 3 minutes by pressing the system button (B) once.
• Once  the eTRV has successfully paired to the Smart Hub, programming of the device or changes to device settings must be done through the konekt app.
• If required, you can quickly switch between manual or program mode on the eTRV by pressing and holding the Menu/Boost button (E) for 2 seconds.

Mounting

The eTRV is easy to install and can be done without draining the heating system as long as you have radiators with a suitable radiator valve. The union nut (G) on the eTRV can be directly attached to all valves with a standard thread size of M30 x 1.5.

Danfoss RA adapter
The adapter provided is required to attach the eTRV to Danfoss RA valves. The RA adapter is pre-tensioned in order to provide a better fit. If necessary use a screwdriver to open the adapter slightly. 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, 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. After clipping onto the valve body, attach the adapter using the provided screw and nut.

Support ring
The valves from different manufacturers may have tolerance fluctuations that make the eTRV sit more loosely on the valve. In this instance, insert the provided support ring into the flange before mounting.

Adaption run

• Once the batteries are inserted, the motor will automatically start. “InS” and the activity symbol ( ) will appear on the display.
• After the eTRV has been mounted successfully, an adaption run (AdA) has to be performed in order to adapt the device to the valve:
• While “AdA” is displayed, press the menu/boost button (E) to start the adaption run.
• “AdA” and the activity symbol ( ) will displayed. During this time, no other operation is possible. After the adaption run has been successful, the display will return to normal.
• If the adaption run has been initiated prior to mounting or if an error message (F1, F2, F3) is displayed, press the menu/boost button (E) and the motor will return to the “InS” position.

Configuration

Automatic operation
In automatic mode, the temperature is controlled in accordance with your set heating schedule. Any manual overrides will be activate until the next change in the heating schedule.

Manual operation
In manual mode, you can adjust the target temperature you would like eTRV to achieve. The target temperature can be set manually using the Plus/Minus buttons on the eTRV or through the app. This temperature remains active until the next manual change.

Holiday Mode
Holiday mode allows you to maintain a constant temperature for a certain period, e.g. during your holidays.

Operating lock
Operation of the device can be locked to prevent settings being changed.

Offset Temperature
As the temperature is measured on the eTRV, the temperature distribution can vary throughout a room. To adjust this, a temperature offset of ±3.5°C can be set. If a nominal temperature of e.g. 20 °C is set but the room only reaches 18°C, an offset of -2.0°C may need to be set.

Boost Function
This will fully open the radiator valves of any eTRVs assigned to the same room to quickly heat the room. The boost will last for 5 minutes and can be activated by pressing the menu/boost button (E) or through the app.
Through the app you can amend the boost duration from 5 – 30 mins.

Replacing batteries
If the symbol for low batteries ( ) appear in the display or in the app, replace with two new LR6/mignon/AA batteries. Once the batteries have been inserted, the eTRV will perform a self-test and an adaption run. The LED will indicate that initialisation is complete by lighting up orange and then 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
• Take them to your local battery disposal point.

Troubleshooting

Low batteries
Provided there is enough voltage, the eTRV will still operate. Depending on the load, it may still be possible to send commands. If the voltage drops too far during a command, the low battery symbol ( ) and error code will be displayed on the device (see section 8.4). In this instance, the batteries must be replaced.

Command not confirmed
If at least one device does not accept a command, the LED (B) will light up red. This may be caused by radio interference (see section 11). Other possible issues may be:

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

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. Warmup devices are designed and produced with 100% conformity to this regulation. During normal operation, the duty cycle is not usually reached. However, intensively repeated device pairing processes may mean that this limit is reached in isolated instances during commissioning.

IMPORTANT: If the duty cycle limit is exceeded, the device may stop working for a brief period. The device will start working normally again after a short period (max. 1 hour).

Maintenance and Cleaning
The device does not require any specific maintenance other than replacing the battery when necessary. To clean, use a soft, clean and lint-free cloth. To remove more stubborn marks, dampen the cloth with warm water. Do not use detergents or chemicals on the devices.

General information about radio operation
Radio transmission is performed on a non-exclusive RF channel, 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.
