- Before opening the device, make sure that it is de-energized.
- Tools may only be used on the device if it has been ensured that it is disconnected from the supply voltage and that any residual electrical charges stored in components have been discharged beforehand.
- Live cables or lines to which the device is connected must always be checked for insulation faults or breakages.
- If a fault is detected in the supply line, the device must be taken out of operation immediately until the defective line has been replaced.
- If these instructions is not clearly state for non-commercial end users in regard to, which electrical characteristic values apply to the device, how external wiring is to be carried out, or which external components or accessories may be connected and what connected loads
- these external components may have, a specialist must always be requested for information. Before commissioning the device, check whether it is suitable for the planned application!
- In case of doubt, it is absolutely necessary to consult experts or the manufacturers of the modules used! Please note that operating and connection errors are beyond our control. We assume no liability for any damage resulting therefrom.

Connecting the thermostat:
The Optima W Basic can be used for various applications, as the thermostat has a voltage-free (potential-free) output! The external sensor is used for temperature measurement e.g. in the floor in combination with an electric underfloor heating system
Description Terminals
- Input terminal for the 230V/AC supply voltage of the thermostat
- Output terminal for connecting the load (potential-free), for connection options, see “Connection of the thermostat”.
- Input terminal to connect the external temperature sensor
App integration and programming:
In order to setup or program the thermostat via Smartphone App, the free TuyaSmart App must first be downloaded and installed from the respective App Store. Minimum Smartphone requirements: iOS9 or newer, Android 4.1 or newer
The following steps show the setup of the TuyaSmart App as well as the integration and programming of the thermostat.
