The MD1 is easy to operate, featuring a large digital touchscreen display and incorporates the latest EcoDesign energy-saving features including Herschel’s open window technology.

    MD1 has a keypad locking feature to prevent unauthorised tampering making it suitable for commercial applications such as hotels, care homes, student accommodation and let properties.  The MD1 is a 16 amp thermostat enabling up to 3.6 kW of Herschel heaters to be connected.
