The Herschel iQ T1 Thermostat pack (including one T1 thermostat plus R1 Receiver) incorporates the very latest energy-saving technology and is specifically designed to regulate Herschel Infrared heaters. Easy to install it is perfect for installations where hard wiring to the MD1 Thermostat would be impractical (for example, if you wish to minimise chasing out walls/cable trunking).

Herschel iQ T1 / R1 SchematicOptional remote control over the internet is available (just add the iQ Hub and download the Herschel iQ App)*.

The T1 pack comprises a battery operated, wireless T1 Thermostat which can be wall mounted or free standing (and also includes one R1 Receiver).

The Receiver must be wired to the mains electricity supply and also to the Herschel heater(s). The T1 and R1 are paired wirelessly and the T1 will then control all R1s which are paired to it.  The T1 pack will control up to 2kW (at 230V supply) of Herschel Infrared heaters on one electrical circuit. To control more heaters in the same zone, or if you wish to use one R1 Receiver per heater, simply purchase additional R1 receivers and pair them to the T1.

The T1 features 3 manual modes and 7 x 1 day programming and is an easy to operate thermostat. The T1 incorporates the latest EcoDesign energy-saving features including Herschel’s open window technology and an adaptive start function ensuring your room is always at the right temperature with the least energy use.

When used in conjunction with the iQ Hub, the T1 Thermostat can also be app-enabled allowing remote control from an App on your smartphone wherever you are – great for ensuring you always return to a warm and cosy property.
