Hand over all the documents with the device if it is transferred to third-parties.
General Function
The programmable radiator thermostat RT2000 BT with pre-programmed, individually adjustable heating and energy saving times allows you to regulate room temperatures using time settings. The device adjusts a radiator valve to control the heat flow to the radiator. The programmable

radiator thermostat RT2000 BT fits on all common radiator valves and is easy to install – it is not necessary to drain heating water or interfere with your heating system.
Intended Use
The programmable radiator thermostat RT2000 BT - in the following called "the device" - is used to regulate any common radiator valve.
The device may only be operated indoors. Any use other than that described in this operating manual is considered unintended use and results in loss of rights related to the terms of guarantee and exemption of liability. This also applies to any reconstruction and modification. The device is exclusively intended for private use.

Installation

Caution! Risk of burns through hot radiator valve! Contact could lead to hands being burned. Allow the radiator to cool down before completing any installation, disassembly or repair work on the device! Wear work gloves!
Assembly of the programmable radiator thermostat is easy and can be completed without the need to drain any heating water or work on the heating system. It is not necessary to use any special tools or switch off the heating system.

natural_image
Technical line drawing of a mechanical component with labeled part '15' (no text or symbols beyond label)The coupling ring included in the supply package (15) fits without accessories on all radiator valves with thread size M30 x 1.5 mm from all common manufacturers such as Heimeier, MNG, Junkers, Landis&Gyr (Duodyr), Honeywell-Braukmann, Oventrop type A, Oventrop AV6, Schlösser, Comap D805, Valf, Sanayii, Mertik Maxitrol, Watts, Wingenroth (Wiroflex) R.B.M, Tiemme, Jaga, Siemens, Idmar.
Also included in the supply package is an adapter for fitting the device to Danfoss RA, Danfoss RAV and Danfoss RAVL radiator valves.

Disassembling the Old Thermostat Head
- Set thermostat head (11) to temperature range ON (or position 5) (see Fig. 1).
This means the thermostat head is no longer pressing on the spindle of the radiator valve and can be removed more easily.
- Unscrew fixing element (9) of the thermostat head and remove the thermostat head.
Installing the New Thermostat Head

Risk of injury! During assembly, be careful not to jam your fingers between the halves of the adapter!

To fit the device to Danfoss radiator valves, you need the adapter provided. To determine which adapter (13) fits which radiator valve, please see Fig. 2 - 4.

natural_image
Pure mechanical component diagram without any text, numbers, or symbols
Risk of injury! The adapters supplied are joined together with plastic tabs. Snapped off edges can be sharp. Break off the plastic tabs carefully and smoothen the sharp eges on the adapter you use with a suitable tool.

The notches (12) on the circumference ensure the adapter fits perfectly.
- If required, slip the adapter (13) that fits the radiator valve onto the valve until the adapter snaps into place.
NOTE: If necessary, use a screwdriver to slightly prise open the adapter in the area of the screw.
- Fix the adapter with the screw and nut supplied (see Fig. 2 or Fig. 3).
NOTE: For the RAV valve type, you also need to place the stem extension (14) onto the valve pin (see Fig. 2).
-
Screw the coupling ring (15) onto the installed adapter or directly onto the radiator valve (see Fig. 1).
-
Fit the device onto the coupling ring.
-
INST. appears on the display. Confirm with OK. ADAP appears on the display.

The device starts the adaptation automatically.
The device adjusts to the regulation path of your radiator valve. For this purpose, the radiator valve is opened and closed several times so that the device learns the end points. This process may take a few minutes under certain circumstances.
After successful adaptation, the device goes into automatic mode.
Disassembly

Caution! Risk of burns through hot radiator valve! Contact could lead to hands being burned. Allow the radiator to cool down before completing any assembly, disassembly or repair work on the device! Wear work gloves!
-
Turn the adjusting wheel (4) to the right beyond the maximum temperature of 28 °C until ON appears on the display.
-
Wait a few seconds until the radiator valve is fully open.
-
Press the lock (16) to release the quick-release latch.

-
Pull the device off the coupling ring (15).
-
Unscrew the coupling ring.
-
If you have used an adapter, remove it and keep it in a safe place.
NOTE: You may have to undo the screw and nut.
