To integrate the DHC Radiator Thermostat into your ecosystem and enable it to communicate with other accessories, you must connect them first. You can connect the DHC Radiator Thermostat to the DHC Access Point via the ONECTA app. It is also possible to create a direct connection to other DHC accessories. If you have already connected the DHC Radiator Thermostat to another DHC accessory, or if you have changed the default settings, you first have to restore the factory settings. First set up your DHC Access Point via the ONECTA app to enable operation of other DHC accessories within your ecosystem.
• Page 17: Start-up To connect the DHC Radiator Thermostat to the DHC Access Point, proceed as follows: Open the ONECTA app. Click on the plus symbol (+). Select the menu item Add Daikin Home Controls. Select Add DHC Accessory. Open the battery compartment by pulling the cover down. Remove the insulation strip from the battery compartment. Connection mode remains activated for 3 minutes. You can manually start the connection mode for another 3 minutes by pressing the system button shortly. Follow the instructions in the app.
• Page 18: Start-up Mounting Read this entire section before starting to mount the accessory. The DHC Radiator Thermostat can be easily 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 union nut attached to the DHC Radiator Thermostat can be used universally for all valves with a thread size of M30 x 1.5.
• Page 19: Start-up By means of the adapter in the delivery, the accessory can also be installed on radiator valves of type Danfoss RA. In case of visible damage to the existing radiator, valve or heating pipes, consult a specialist. Remove the old thermostat dial from your radiator valve. Rotate the thermostat dial to the maximum value anti-clockwise. The thermostat dial then no longer presses against the valve spigot, making it easier to remove. There are different ways the thermostat dial could be fixed. Union nut: Unscrew the union nut in an anti-clockwise direction. Snap-on fastenings: Thermostat dials that have been attached with snap-on fastenings can be easily released. Compression fitting: The thermostat dial is held in place by a mounting ring.
• Page 20: Start-up instructions include removing the thermostat dial from the valve. For threaded connections, loosen the set screw to remove the thermostat dial. Mount the DHC Radiator Thermostat with the union nut to the radiator valve. An adapter for Danfoss RA valves is available if needed. The RA adapter is designed for a better fit with pre-tension. Use a screwdriver during installation if necessary and adjust the adapter as needed. Ensure the adapter is properly seated by aligning the pins with the notches on the valve. Check that a suitable adapter is clipped on securely.
• Page 21: Start-up Be careful not to get your fingers caught between the two halves of the adapter. After clipping the adapter onto the valve body, fix it using the provided screw and nut. Support ring The valves from different manufacturers may have tolerance fluctuations that make the DHC Radiator Thermostat more loosely seated on the valve. In this case, the provided support ring should be placed into the flange before mounting the accessory. Adaption run Once the batteries have been inserted, the motor reserves are displayed. After the DHC Radiator Thermostat has been mounted successfully, an adaption run has to be performed to adapt the accessory to the valve. As soon as AdA is displayed, press the menu/boost button to start the adaption run. AdA and the activity symbol are displayed during the adaption run.
• Page 22: Configuration The configuration of the accessory can be set up completely in the ONECTA app. For further information on configuration of the accessory without using the DHC Access Point, see the DHC Application Guide. The following modes and settings can be adjusted: Automatic mode Manual mode Offset Programming a schedule Operating lock (not yet available) Holiday mode
• Page 23: Automatic mode controls temperature according to the set heating schedule, with manual changes active until the next scheduled change. In manual mode, temperature is controlled based on the current setting via push-buttons, remaining active until the next manual change. A temperature offset of ±3.5 °C can be set to adjust for temperature distribution variations in a room. If the nominal temperature is set at 20 °C but the room temperature is only 18 °C, an offset of -2.0 °C should be set. The temperature offset feature is not yet available in the ONECTA app and cannot be changed at this time.
• Page 24: Configuration Programming a schedule allows you to create a schedule with time slots for heating and cooling according to your personal needs. Operating lock can be used to avoid unintended changes to settings. This setting is not yet available in the ONECTA app. Holiday mode can be activated in the ONECTA app to put your system into standby. The holiday mode is visualized on your Daikin Altherma and on the Air Conditioning units in the ONECTA App. For further information, see the DHC Application Guide.
• Page 25: Operation After connecting and mounting the DHC Radiator Thermostat, simple operations are available directly on the accessory. Temperature: Press the plus and minus buttons to manually change the temperature. In automatic mode, manual changes are activated until the next point at which the schedule changes. Afterwards, the defined heating schedule will be activated again. In manual mode, the temperature remains activated until the next manual change. Boost function: Press the boost button briefly to activate the boost function. The boost function will heat up the radiator quickly and shortly by opening the valve.
• Page 26: Replacing batteries If the symbol for empty batteries appears, replace the used batteries by two new LR6/mignon/AA batteries. You must observe the correct battery polarity. To replace the batteries of the accessory, proceed as follows: Open the battery compartment by pulling it down. Remove the batteries. Insert two new 1.5 V LR6/mignon/AA batteries. Make sure that you insert them the right way round. Close the battery compartment. Pay attention to the flashing signals of the LED while inserting the batteries. After inserting the batteries, the accessory will perform a self-test. Afterwards, initialisation is carried out. The LED will light up orange and green to indicate that initialisation is complete.
• Page 27: Replacing batteries 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. Used batteries should not be disposed of with regular domestic waste. Instead, take them to your local battery disposal point.
• Page 28: Troubleshooting Weak batteries The accessory will remain ready for operation even if the battery voltage is low. It may be possible to send transmissions again repeatedly after a brief recovery period. If the voltage drops too far during transmission, the empty battery symbol and the corresponding error code will be displayed. In this case, replace the empty batteries with two new batteries.
• Page 29: Troubleshooting The wireless DHC accessories operate in specific frequency bands. It is legally required to limit the transmission time of devices to minimize the risk of interference. The ‘duty cycle’ is the maximum transmission time expressed as a percentage of 1 hour. If the total allowed transmission time is reached, the DHC accessory will stop transmitting. For example, a device with a duty cycle limit of 1% can transmit for only 36 seconds in 1 hour. DHC accessories comply with this limitation and use two frequency bands with duty cycles of 1% and 10%. During normal operation, the duty cycle limit is usually not reached. The LED of the accessory lights up red if the limit is reached during start-up or fresh installation. The accessory may be non-responsive for a short period until the transmission time limit expires.
• Page 30: Troubleshooting Error codes and flashing sequences F1 - Valve drive sluggish: Check whether the valve pin is stuck. F2 - Actuating range too wide: Check the fastening of the DHC Radiator Thermostat. F3 - Adjustment range too small: Check whether the valve pin is stuck. Battery symbol - Battery voltage too low: Replace the batteries of the accessory. Battery symbol - Valve moved to error position: Replace the batteries of the accessory. If empty batteries are not replaced, the DHC Radiator Thermostat moves to a valve error position. This avoids that the set temperature in the room cannot be reached anymore due to a low battery. A valve error position of 15% is set in the factory settings.
• Page 31: Troubleshooting Error and flashing codes Operating lock activated Deactivate the operating lock. Communication problem with DHC Access Point or connected accessory Check the connection with the DHC Access Point or the connected accessory. Radio transmission/attempting transmission is completed. Transmission confirmed Continue the operation. Transmission failed or duty cycle limit is reached Try again (see or “9.2 Duty cycle” on page 29). Connection mode active Follow the instructions in the app to add accessory (see “5.1.1 Connecting to the DHC Access Point” on page 16).
• Page 32: Troubleshooting Error and flashing codes Fast orange flashing indicates connection mode active. Activate the connection mode of the accessory you want to connect. Short orange lighting (after green or red confirmation) means batteries are empty. Replace the batteries. 6x long red flashing indicates accessory defective. Contact your reseller. 1x orange and 1x green lighting (after inserting batteries) refers to the test LED. After the test LED has stopped, you can continue. Long and short orange flashing (alternating) indicates update of accessory software (OTAU). Wait until the update is completed.
• Page 33: Restore factory settings The factory settings of the accessory can be restored. If you do this, you will lose all your settings. To restore the factory settings of the accessory, proceed as follows: Open the battery compartment by pulling the battery compartment down. Remove a battery. Insert the battery again and long press the system button until the LED quickly starts flashing orange. Release the system button. Long press the system button again, until the LED lights up green. Release the system button to finish the procedure. The accessory will perform a restart.
• Page 34: Maintenance and cleaning The accessory 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 accessory using a soft, lint-free cloth that is clean and dry. You may dampen the cloth a little with lukewarm water in order to remove more stubborn marks. Do not use any detergents containing solvents, as they could corrode the plastic housing and label.
• Page 35: 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. Environmental factors such as humidity in the vicinity have an important role to play, as do on-site structural/screening conditions. Daikin Europe N.V. declares that the radio equipment type DHC EKRRVATR2BA is in compliance with the Directive 2014/53/EU. The original declaration of conformity is available from the EKRRVATR2BA product pages.
