Please note: the updated T2 and R2 thermostat and receiver are not compatible with older T1 and R1 legacy products.
Always ensure that any thermostat or controller is placed in a location away from any hot or cold spots.
Controllers or thermostats should not be installed in bathrooms. If you want to control heaters in your bathroom, you will need to make sure the heater is wired into the controller in a location which falls outside the “wet” bathroom zones – namely, at least 60cm away from any source of running or splashing water. Receivers must not be installed anywhere where there will be risk of water contact – whether by dripping, splashing, or touching with wet hands.
This thermostat is battery powered and can be wall mounted DIY using the mounting plate and fittings provided. Each unit also comes with a stand if you prefer your thermostat to be freestanding. An unlimited number of R2 Receivers can be connected to the T2 Thermostat. It requires 2x AAA batteries.
R2 receivers must be hardwired into your heaters and a mains power supply by a qualified electrician. R2 Receivers have a max load of 10 Amps (2300W at 230V); however, the manufacturer recommends an 8.5 Amp continuous load (1955W at 230V) to ensure the longevity of the receiver.
The MD2 is not suitable for DIY installation and will require a single gang 46mm deep pattress box for recessing into a wall, with access to the mains circuit powering the heaters. This is a job for a qualified professional.
The Herschel iQ System comes with a 2 Year Manufacturer’s Warranty.

The Herschel iQ system provides convenient temperature management for every Herschel heater in your property, using either the hardwired MD2 Thermostat, or the wireless T2 Thermostat in conjunction with R2 Receivers. These iQ thermostats are designed for use with Herschel infrared heaters that do not come with built in receivers.
Both of these thermostat systems are WiFi ready and can be paired with the Smart Life app for easy programming and distance control. Using the app, you can create a daily and weekly schedule down to the minute, as well as use your heating with Amazon Alexa or Google Home for hands-free voice control.
Configuration 1: MD2 Thermostat
- Smaller heating systems
- Hot yoga studios
Herschel heaters hardwire directly into the MD2 Thermostat, which can be controlled via the intuitive touchscreen display, or remotely via the Smart Life app. As this thermostat is connected directly to your heaters, it does not require any receivers to operate.
To control your whole home heating system through the app you will need to purchase a separate MD2 thermostat for each heater or group of heaters up to 3600W. The MD2’s control features include full weekly programming, three energy-saving modes and open window detection. Unlike the T2 controller, the MD2 can handle temperatures up to 45 °C, making it a superb choice for hot yoga studios.
Configuration 2: T2 Thermostat + R2 Receivers
- Larger systems or systems that may be expanded later
- Grouping heaters together
The T2 thermostat communicates with R2 receivers wirelessly via a radio frequency, switching your heaters on or off according to your program. This system is compatible with the Smart Life app and uses the R2 receiver as a WiFi gateway. So, when any changes are made using the app, your heating updates automatically, taking room temperature readings via the T2 thermostat.
The T2 thermostat also includes manual weekly programming, open window detection and adaptive start features. The boost button on each receiver gives you an extra degree of flexibility, allowing you to temporarily bypass the T2’s commands and increase the heat output of a single heater if you need a little more warmth.
R2 receivers can be used to control multiple heaters up to 1955W. You will need to purchase an R2 receiver for each heater or group of heaters you want to control with the T2 thermostat. If you want to create separate heating zones in your home, you will need to purchase an additional T2 thermostat for each area. This allows you to accommodate the differing heating requirements of separate areas of the home without compromising comfort or energy efficiency. Each T2 thermostat can be paired with an unlimited number of R2 receivers, giving you the option of using it as a central point of control for your whole home.
The T2 thermostat and R2 receivers need to be used together in order to work as intended. They will not operate separately.
