With this Schneider Electric Merten System M 2A thermostat insert for ZigBee, you can control the indoor temperature. This product is compatible with 2A relays for hydronic systems (hydronic radiators, hydronic underfloor heating, circulation pumps, and motorized valves). The communication port protocol of this device is Zigbee 3.0, integrated into the Wiser Home System. The standby power consumption (no load switching) must be less than 0.5 W. The dimensions are (H) 52 mm x (W) 52 mm x (D) 28 mm. This product acts as a room temperature controller for hydronic or electric applications. This device also functions for heating or cooling hydronic underfloor systems. The smart thermostat connection or standalone mode is easy to set up with the Merten Design M, which features a capacitive touch display. The universal input allows you to save energy in combination with a proximity sensor when no one is in the room. This device is compatible with gas boilers, heat pumps, or oil boilers. It is easy to install and configure with the local display. Remote access and simple scheduling with the Wiser Home App are available. The device can be installed in a CE60 wall box. It must be operated with an input power of 230 VAC single phase +/- 10% at 50-60 Hz. It achieves an IP30 protection rating. Its transmission frequency is 2.4 GHz, and the range is 30 m in open space. This device complies with CE and CB certifications. It is a quick installation solution that does not require an internet connection. Since the device is 2A, there is a potential-free output that is compatible with NC and NO valves or other loads up to 2A resistive. This is a solution for Merten customers who need connectivity and remote control as part of the Wiser Home System.
