Room thermostat color | Optima W-FC

Room thermostat with color display

Flush-mounted thermostat with color display. For controlling electric and central heating, based on set temperature and time.

Heating control with smartphone

You can control this modern clock thermostat via Wi-Fi, using an app from Tuya. It can also be paired with other devices via Tuya and/or IFTTT. The thermostat is also supported by Tuya Google assistant, Alexa and Siri.
The handsome room thermostat is designed for installation in an (existing) 230-volt wall box. Thanks to its voltage-free switching contact, it is also suitable as a replacement for conventional a 2-wire central heating control.

Menu-driven ease of use

Advanced built-in full-color touchscreen thermostat with nice and clear graphic display. Pleasant to use thanks to clear icons. The menu-driven operation works easily in practice.

The thermostat has both an internal sensor and an external (floor) sensor, which is included.

•    Easy mounting in normal wall-mounted box
•    Control via App, 7 x 4 switching moments per week
•    Floor sensor, room sensor, or combination of both
•    Temperature value is given in Celsius
•    Adjustable hysteresis and background lighting
•    Open window detection when using the room sensor
•    Combines with other Tuya-compatible products
•    Menu driven and manual programming
•    Via TuyaSmart app (minimum IOS9, Android 4.2)
•    Linkable with IFTTT, Google Assistant, SIRI and Alexa

For central heating and electric (floor) heating

You can connect electric floor heating and radiant panels directly to the switching contact of the flush-mounted room thermostat. To do this, you must supply the switching contact with 230 Volt (looping through the phase).
Please note: to replace a 2-wire central heating thermostat, you do need mains voltage for the display.
