Room thermostat II help

The Room thermostat II can be installed in a few simple steps. All you need is the Bosch Smart Home app and the accessories included in the packaging. After starting the Bosch Smart Home app, it will guide you through the individual installation steps.

You can find further information in theInstruction manual.

You can connect a cable with an external temperature sensor to the sensor input and use it as a floor sensor, for example. The sensor cable is available as an optional accessory.

Your Room thermostat II / Room thermostat II 230 V is still functional. It logs on to the Smart Home controller again only after a short time.

Our Bosch Smart Home Room thermostat II has a protection class of IP 20. The first digit "2" stands for "Protected against solid foreign objects with a diameter of less than 12.5 mm" as well as "Protected against access with a finger". The second digit "0" indicates that the electrical device is not protected against water and moisture.

Our Bosch Smart Home Room thermostat II 230 V has a protection class of IP 21. The first digit "2" stands for "Protected against solid foreign bodies with a diameter of less than 12.5 mm" as well as "Protected against access with a finger". The second digit "1" indicates that the electrical device is additionally protected against vertically falling dripping water.

The sensor in the Twinguard is a multiple sensor that can measure temperature and humidity in addition to VOC. Due to the specific requirements for Smoke alarms, the measurement of temperature is only possible at regular intervals and not dynamically after temperature changes.

To activate the parental lock of the Room thermostat, proceed as follows:

1) Open Bosch Smart Home App >> Device settings >> select corresponding Room thermostat II / Room thermostat II 230 V >> set "Child lock" option to "on".

2) Additional activation of the child lock: Press the system key for 3 seconds until the display "LCK" appears.

The pause symbol in the display of the Room thermostat II / Room thermostat II 230 V means that the valve is closed and no more control takes place. This is the case, for example, when the "Heating pause" is active in the "Climate manager" service. The frost protection function and the calcification protection remain active during this time.

You can connect any number of Radiator thermostats II to a Room thermostat II. If you have assigned several devices to a Room thermostat II, you will find the corresponding overview under "Controlled devices" on the device configuration page of the Room thermostat II.

Radiator thermostats I are no longer compatible with Room thermostat II.

Currently we cannot offer you any historical data yet.

The humidity is shown on the display of the device, as well as in the Bosch Smart Home app under the room overview.

The lifetime of the batteries is approx. 1 year with typical use. If the battery capacity drops below a critical level, the Bosch Smart Home app will inform you in good time. Likewise, the battery symbol lights up on the display of the Room thermostat II and the LED starts flashing red.

Under Menu >> Services >> Climate manager >> Heating pause is indicated after activation by a pause symbol on the display of the corresponding thermostats and a note in the Smart Home app. The thermostats are then switched off in summer, for example. Scenarios and automations then ignore the temperature settings for the corresponding room.

You can restore the delivery state of the device as follows:

Open the battery compartment and remove one of the batteries. While keeping the knob pressed, reinsert the battery. Press and hold the knob until the Room thermostat status LED flashes orange and the display shows "RES". Now release briefly and press and hold the knob again until the LED lights up green. The device will then restart. Please note that it may take a few seconds until the Room thermostat is ready for operation again.

When resetting to factory settings, only the settings and information on the device and not on the Bosch Smart Home controller will be lost.

To re-teach the device, first delete it in the device management of the Bosch Smart Home app and then add it again via the usual teach-in process.

To activate the lighting of your Bosch Smart Home Room thermostat II or Room thermostat II 230 V, briefly press the system button on the control unit.

With the Room thermostat II 230 V, you can also turn the system key for this purpose.

The Smart Home Room thermostat II is the optimal addition to your Radiator thermostats II. The Room thermostat II is freely placeable. Instead of directly on the radiator as before, the Room thermostat can now measure the temperature in the room where it is most important to you. Especially in large rooms or with concealed radiators, the temperature control with the smart Room thermostat II becomes much more precise and efficient. You gain comfort and save energy when the room is heated only as much as necessary.

The communication between Room thermostat II / Room thermostat II 230 V and the Bosch Smart Home controller takes place via the radio standard Zigbee (2,4Ghz)

Room thermostat II 230 V requires a 230 V power supply. It has a switching actuator (Relay) to switch air conditioning systems with wired control (with and without potential).

Room thermostat II is powered by 4xAAA batteries. It does not have its own switching actuator (Relay) and can only send information to other smart end devices via radio through the controller.

The exact scope of delivery of the Bosch Smart Home Room thermostat II can be found on the corresponding product page of our webshop under the followingLink.

Each device measures the sensor values for itself at its location. Due to measurement tolerances and local conditions as well as different positions in the room (ceiling, wall, windows, doors), the measured values may be different.
