Product details

With the Wiser room temperature thermostat module in system design, you can easily control your room temperature. The room temperature thermostat is compatible with both inserts: a 16A relay for electric heating (underfloor heating, radiators, hydronic underfloor heating) and a 2A relay for hydronic systems (radiators, underfloor heating, circulation pumps, and motorized valves). The thermostat supports the Zigbee 3.0 wireless protocol and can be integrated into the Wiser Home System. The power consumption in standby mode (no load switching) must be less than 0.5W. The dimensions are (H) 71 mm x (W) 71 mm x (D) 20 mm, and the weight is 45g. The room temperature module serves as a temperature controller for electric underfloor heating with a floor sensor (only in combination with the 16A relay insert). The thermostat also acts as a room temperature controller for hydronic or electric applications and as a heating or cooling solution for hydronic floor systems (only in combination with a 2A relay). It is a smart Wiser thermostat or stand-alone with a display for easy setup, integrated into the system design. Remote access and easy scheduling with the Wiser Home App are also possible. The thermostat must be operated with an input power of 230VAC single-phase +/- 10% at 50-60Hz and can be installed in a CE60 wall box. It achieves an IP30 protection rating. The transmission frequency is 2.4GHz, and the operating range is 30m in open space. The room temperature thermostat complies with CE and CB certifications. It offers a quick installation solution without the need for an internet connection. The color of the thermostat is lotus white (RAL 9003). The universal input allows for energy savings in combination with a sensor when no one is in the room. A heating solution for customers who utilize connectivity and remote control as part of the Wiser Home System.
