T2 Wireless Thermostat Overview

The Herschel iQ T2 Thermostat and R2 receiver regulate Herschel Infrared Heaters, incorporating energy-saving features like 'Open Window' technology and 'Adaptive Start'. The T2 thermostat offers 7-day programming, Eco, and Manual modes. It controls the R2 receiver, which switches the heaters on/off and acts as the internet gateway for remote control via the SmartLife App. The R2 receiver supports up to 10 amps; ensure sufficient R2 units for the heating load. Each R2 must be paired to a T2. The R2 provides a limited Boost function and no temperature control on its own. The appliance is rated IP20 and must be installed outside bathroom splash zones.
