If you use several devices in a room, you should teach in all devices onto one another.

9.2 Assembly

Please read this section thoroughly before you begin installing the device.

The SilverCrest Smart Home radiator thermostat can be easily installed without draining the heating water or intervention in the heating system. No special tools are required and the heating does not need to be turned off.

The cap nut (A) mounted on the radiator thermostat is designed for universal use and does not require any accessories to fit all valves with M30 x 1.5 mm threads from major manufacturers such as

■ Heimeier
■ MNG
■ Junkers
■ Landis&Gyr (Duodyr)
■ Honeywell-Braukmann
■ Oventrop
■ Schlösser
■ Comap
■ Valf Sanayii
■ Mertik Maxitrol
■ Watts
■ Wingenroth (Wiroflex)
■ R.B.M
■ Tiemme
Jaga
Siemens
Idmar

The adapter included in the package contents also enables the device to be installed on radiator valves of the Danfoss RA type (see section '9.2.2 Adapter for Danfoss RA'.

9.2.1 Installing the radiator thermostat

Caution! Please consult a professional if there is noticeable damage to the existing thermostat, the valve or the heating pipes.

Dismantle the old thermostat head from your radiator valve.

- Turn the thermostat head counter-clockwise to the highest value (H) (see Figure 4). The thermostat head no longer presses against the valve spindle and is therefore easier to remove.

The thermostat head may be attached using various means:

• Cap nut: Unscrew the cap nut in the counter-clockwise direction (I). You can then remove the thermostat head (J).
• Snap-on fasteners: You can easily loosen thermostat heads that are attached in this manner by turning the fastener/cap nut slightly counter-clockwise (I). You can then remove the thermostat head (J).
• Clamp fittings: The thermostat head is held by a mounting ring, which is held together by a screw. Loosen this screw and remove the thermostat head from the valve (J).
• Screw connection with grub screws: Loosen the grub screw and remove the thermostat head (J).

After dismantling the old thermostat head you can put the SilverCrest Smart Home radiator thermostat onto the radiator valve using the cap nut (A) (see Figure 5).

If necessary, use the included adapter for Danfoss RA valves (see section '9.2.2 Adapter for Danfoss RA') or the included support ring (see Section '9.2.3 Support ring').

9.2.2 Adapter for Danfoss RA

The included adapter is required for installation on Danfoss RA valves.

The RA adapter was produced to achieve a better fit with pre-stressing. Use a screwdriver during installation if necessary and bend the adapter open slightly near the screw (see following figure).

The Danfoss valve bodies have lengthwise notches around them (1) that also ensure a better fit of the adapter after it has snapped into place.

During installation, make sure that the studs on the inside of the adapter (2) fit into with the notches (1) on the valve. Snap on the appropriate adapter for the valve completely.

WARNING! Be careful not to pinch your fingers between the two halves of the adapter.

After snapping the adapter onto the valve body, fasten it with the included screw and nut.

9.2.3 Support ring

The valves produced by some manufacturers have small diameters on the part of the valve that extends into the device, which results in a loose fit. In this case, the included support ring (K) should be inserted into the flange of the device prior to installation (see Figure 6).

9.3 Adaptation run

After the batteries are inserted, the motor initially retracts to facilitate the installation. 'InS' and the activity icon (n) are displayed during this process.

Once the radiator thermostat has been successfully installed, an adaptation run then needs to be performed to adjust it to the valve.

Do this by proceeding as follows:

- When 'AdA' appears on the display, press the Menu/Boost button (G) to start the adaptation run.

The radiator thermostat now performs an adaptation run. 'AdA' and the activity icon (N) are shown on the display. Operation is not possible during this process. Once the adaptation run is complete, the display switches to show its usual information.

If the adaptation run was initiated prior to installation or if an error message (F1, F2, F3) is displayed, press the Menu/Boost button (G) and the motor returns to the 'InS' position.

10. Configuration menu

If you use the radiator thermostat without an access point, you can select the following modes directly on the device after initial use via the configuration menu and make settings to adapt the device to your personal requirements.

The configuration menu can only be accessed if the radiator thermostat has not been registered at an access point yet.

If the empty battery icon (☐) appears on the display or in the app, replace the old batteries with two new type LR6/Mignon/AA batteries. When doing so, observe the correct polarity of the batteries.

To insert new batteries in the radiator thermostat, proceed as follows:

• Slide the battery compartment cover down to remove it (B) (see Figure 7).
• Remove the batteries.
• Insert two new 1.5 V LR6/Mignon/AA batteries into the battery compartment according to the polarity shown on the marking (see Figure 8).
• Close the battery compartment cover again.
• After the batteries have been inserted, take note of the flash sequences on the LED (see section '13.4 Error codes and flash sequences').

After the batteries have been inserted, the radiator thermostat first performs a self-test for about two seconds. Then initialisation is carried out. The LED turns orange and green to indicate test completion.

DANGER! If the batteries are not replaced properly, there is a risk of explosion. Only replace with the same batteries or batteries of the same type. Batteries must never be recharged. Do not throw batteries into a fire. Do not expose batteries to excessive heat. Do not short the batteries. There is a risk of explosion!

13. Troubleshooting

13.1 Low battery capacity

If the voltage allows, the radiator thermostat will also be operational when the battery capacity is low. Depending on the load, after a brief battery recovery period, the alarm signals may be transmitted again multiple times.

If the voltage fails again during transmission, the empty battery icon (☐) and the error code will be displayed on the device (see section '13.4 Error codes and flash sequences'). In this case, replace the empty batteries immediately with two new batteries of the same type in order to guarantee safe operation (see section '12. Changing the batteries").

13.2 Command not confirmed

If at least one receiver does not confirm a command, the LED will turn red at the end of the faulty transmission. The reason for faulty transmission may be due to radio interference (see section '16. General information on radio interference"). Possible causes of the faulty transmission are:

• Receiver batteries are dead
  • The receiver cannot be reached

• The receiver cannot carry out the command (load failure, mechanical blockade etc.)
- The receiver is faulty.

13.3 Duty cycle

The duty cycle describes a legally regulated limit on a device's transmission time in the 868 MHz range. The aim of the regulation is to guarantee the functioning of all devices operating in the 868 MHz range. In the 868.0–868.6 MHz frequency range that we use, the maximum transmission time for any device is one per cent per hour (that is, 36 seconds an hour). When the one percent limit is reached, the devices are no longer able to transmit a signal until the time limit has passed. In accordance with this guideline, SilverCrest Smart Home powered by Homematic IP devices are developed and produced in full compliance with all relevant standards.

In standard mode, the duty cycle is generally not reached. However, in certain cases, it may be reached during initial use or installation of a system due to the increased, radio-intensive teach-in processes. If the duty cycle limit is exceeded, the device LED (D) will emit a long red light and the device may stop working temporarily. The device will then start working again after a short time (one hour maximum).

14. Restoring the factory settings

It is possible to reset the device's factory settings. During a restore, any preferences you have set will be lost. Carry out a factory reset if you are giving the device away or if a malfunction cannot be resolved.

To restore the radiator thermostat's factory settings, proceed as follows:

• Slide the battery compartment cover down to remove it (B) (see Figure 7).
• Remove the batteries.
• Reinsert the batteries as per the polarity symbols (see Figure 8) and simultaneously press and hold the System button (B) for four seconds until the LED begins to flash orange rapidly (see Figure 3). The display shows 'res'.
• Now take your finger off the System button.
• Press the System button again for four seconds until the device LED (D) turns green.
  • Take your finger off the System button to complete the factory setting restore.

The device will restart.

Once the factory reset is complete, the corresponding devices will also need to be configured again.

15. Storing the device when not in use

If you do not plan to use the radiator thermostat for an extended period, remove the batteries from the battery compartment to prevent them from leaking. Otherwise, this could damage the device.

Then store the radiator thermostat in a clean, dry location.

16. General information on radio interference

The radio transmission will be transferred on a non-exclusive transmission route, which is why is it not possible to rule out faults. Further interference can be caused by switching procedures, electric motors or faulty electrical devices.

The range inside buildings can differ greatly from the range in free field. In addition to the transmitting capacity and the receiver's reception properties, environmental influences such as humidity and structural conditions on site also play an important role here.
