The ENGO E40-BATB is a battery-powered ZigBee 3.0 programmable smart thermostat designed for precise and reliable heating control in homes and offices. With its slim, surface-mounted design and clear LCD display, it provides an easy and flexible way to manage radiator, underfloor, or cooling systems without the need for wired installation. Powered by two AA batteries, the thermostat is ideal for quick retrofits and locations where mains wiring is not practical.

Built on ZigBee 3.0 and 868 MHz wireless communication, the E40-BATB integrates seamlessly into the ENGO ecosystem. It pairs directly with ENGO receivers, relays, control modules, and radiator heads, enabling smooth installation and stable operation. Thanks to ENGO binding, the thermostat can operate offline without Wi-Fi or internet access, directly linking with supported devices. For full smart control, simply connect the ENGO Smart gateway to access the mobile app, remote scheduling, automation, and voice commands via Alexa or Google Assistant.

The thermostat supports heating and cooling modes with advanced TPI and hysteresis algorithms, ensuring consistent comfort and energy efficiency. Users can program daily or weekly schedules directly on the device, helping optimise heating performance and reduce energy costs. Supporting up to six electronic radiator heads in one room, it provides even temperature distribution and control flexibility.

Additional features include frost protection, minimum and maximum setpoint limits, PIN-protected settings, key lock for child safety, valve protection, and OTA firmware updates. Measuring the room temperature away from the radiator helps improve accuracy, while the wireless design eliminates the need for invasive wiring.

By choosing the ENGO E40-BATB, users benefit from maximum flexibility, simplified setup, and long-term compatibility — making it a future-ready choice for wireless smart heating control.
