Room thermostat Curve SL11616W white

Smart Temperature Control for Your Home

The smart Wi-Fi room thermostat with rotary knob enables comfortable and precise control of your heating directly in the room. It is suitable for water-based underfloor heating systems as well as gas combi boilers, thus supporting modern heating control in smart homes. Thanks to the intelligent room temperature control, you can conveniently set the desired temperature and adapt your heating behavior more effectively to your daily routine.

Suitable for underfloor heating and gas combi boilers

The room thermostat features a relay output for controlling 230 V actuators, allowing it to be integrated into compatible heating systems. The heating and cooling function enables flexible use depending on the system employed. With a temperature accuracy of 0.5 °C, the Wi-Fi thermostat supports consistent room temperature regulation, contributing to greater control in your living space.

Direct Wi-Fi connection without a gateway

The thermostat connects directly to your 2.4 GHz Wi-Fi and does not require an additional gateway. This makes it particularly suitable for smart home retrofitting if you want to expand your existing heating control system. Via the Smart Life App, you can set individual schedules and create automated scenes to comfortably manage recurring daily routines.

Modern design with rotary knob and LED display

The mechanical rotary knob in a curve design combines classic operation with modern smart home technology. The glass surface and integrated LED display provide a clear, elegant appearance and easy operation directly on the device. The child lock helps prevent unintentional changes to the settings, making the thermostat suitable for everyday use in households with children.

Easy integration into standard flush-mounted boxes

The Wi-Fi room thermostat is designed for installation in standard 55 x 55 mm cover frames and standardized flush-mounted boxes. It features an integrated sensor; external sensors can optionally be used if suitable for the respective installation. In case of a power outage, saved data is retained, allowing for convenient continued use after power is restored. This makes the thermostat a sensible solution for anyone looking to modernize and smarten up their heating control.

Is there a way to permanently display the time on the thermostat display?

The display design can be changed in the app. Permanently displaying the time on the display is currently not possible.

Is the thermostat compatible with my gas boiler with a potential-free switching contact?

The room thermostat SL11616W has the potential-free switching contact at No. 7 and 8.

Are they compatible with any actuator (on the underfloor heating manifold), or are specific actuators necessary for regulating underfloor heating?

The thermostat is compatible with any actuator.

What is the standby consumption?

The standby consumption is <0.5W.

Does the room thermostat have a cooling function?

Yes, the room thermostat SL11616W has a cooling function, which can be activated in the Smart Life app or via the extended settings of the room thermostat.

Is there a child lock?

Yes, the child lock can be activated and deactivated by pressing and holding the "down arrow button" for a few seconds.

Can I use the room thermostat without a smart home hub?

No bridge or similar is required for connection to the Smart Life/Tuya app. The room thermostat can also be controlled "non-smart", without any app connection.

Which actuators are compatible with the thermostat?

The SL06116W is compatible with all commercially available 230V actuators, both normally closed (NC) and normally open (NO) models. The contact capacity is 3A, which is sufficient for common underfloor heating actuators.

How accurate is the thermostat's temperature measurement?

The integrated sensor measures the room temperature with an accuracy of ±0.5 °C. The temperature setting range is between 5 °C and 35 °C, while the display can show temperatures from 1 °C to 70 °C.

A deviation of about 1–2 °Cis within the normal range for the SIRO Smart Room Thermostat SL06116W. This is because room air, radiators or actuators, and the internal temperature sensor never behave exactly the same physically. Small differences between the measured and actually perceived room temperature are therefore technically unavoidable.

Can I control multiple thermostats in different rooms using one app?

Yes, with the Smart Life app, you can centrally manage any number of SIRO thermostats. Each device can be individually named and assigned its own schedules. The Smart Life app also allows you to create scenes for multiple rooms simultaneously.

How long do settings last in case of a power outage?

In the event of a power outage, your saved settings and schedules will not be lost. Since the thermostat is controlled via the cloud, all data is stored online and automatically synchronized as soon as the power and internet connection are restored. During the power outage, no control or temperature regulation is possible, but after restoration, the thermostat will automatically resume operation with the stored cloud data.

Please note that in individual cases, after longer power or internet outages, the thermostat may require a new Wi-Fi connection before the connection to the cloud is fully re-established.

Does the thermostat also work with ZigBee or Bluetooth?

No, the SL06116W operates exclusively via Wi-Fi in the 2.4 GHz band. The direct Wi-Fi connection has the advantage that no additional gateway is required.

What is the diameter of the terminals for the cables?

The terminals are designed for cable cross-sections up to 2.5 mm². This corresponds to the standard for installation cables in home technology. The terminals are located on the back and are easily accessible after installation. 

Do I need a neutral conductor for installation?

Yes. A neutral conductor (N) is absolutely necessary for installation. Without a neutral conductor, proper connection is not possible.

Is there a vacation function or frost protection?

The thermostat has programmable schedules with which you can set a setback during your absence. The minimum temperature of 5°C serves as frost protection. You can adjust the temperature at any time while you're away using the app.
