MD2 Wired Thermostat
The Herschel iQ MD2 is a 16 amp thermostat enabling up to 3.6 kW of Herschel Heaters to be

powering the heaters. Built-in wifi enables control via the internet using the SmartLife App.
MD2 is easy to operate and incorporates Herschel's open window technology to save energy.
MD2 has a keypad locking feature to prevent unauthorised tampering with the settings and it can
be programmed to control zones up to 45°C, making it suitable for commercial use and for
specialist high temperature applications such as hot yoga studios.
MD2 features Manual, Eco and 7 day programming modes with 4 periods per day. The MD2 will
operate your Herschel heater(s) by turning them ON if the room temperature is lower than the
