    Please 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 receiver 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.

    T1 Thermostat

    This thermostat 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 free standing. An unlimited number of R1 Receivers can be connected to the T1 Thermostat.

    R1 Receivers

    R1 receivers must be hardwired into your heaters and a mains power supply by a qualified electrician. R1 Receivers have a max load of 10 Amps (2300W at 230V), however, the manufacturer recommends a 8.5 Amp continuous load (1955W at 230V) to ensure the longevity of the receiver.

    MD2 Thermostat

    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.

The Herschel iQ system provides convenient temperature management for every Herschel heater in your system, using either the standalone WiFi controllable MD2 Thermostat or the wireless T1 Thermostat in conjunction with as many individual R1 Receivers as you need to connect your heating network. The iQ system is the first choice for infrared heaters that do not come with built in receivers such as the Herschel Inspire range of infrared panels.

Configuration 1: MD2 Thermostat + Smart Life App

Individual Herschel heaters hardwire directly into the MD2 Thermostat for en-masse control. The thermostat can be controlled in-situ, via the intuitive touchscreen display, or remotely via the Smart Life app. The app also enables voice control integration through Amazon Alexa or Google Home.

To control your whole home heating system through the app you will need to purchase a separate MD2 thermostat for each heater or cluster of heaters up to 3600W. The MD2’s control features include full weekly programming, three energy-saving modes and open window detection. Unlike the other controllers in the iQ system, the MD2 can handle temperatures up to 45 °C, making it a superb choice for hot yoga studios.

Configuration 2: T1 Thermostat + R1 Receivers

The T1 thermostat sends out commands wirelessly via a radio frequency. Heaters wired into the R1 receivers pick up these signals and switch your heaters on or off accordingly. Heaters paired with the thermostat will benefit from the T1s comprehensive control features, which include weekly programming and open window detection. The heat boost button on each receiver gives you an extra degree of flexibility, allowing you to temporarily bypass the T1s commands and increase the heat output of a single heater if you need a little more heat in a specific location for a short period of time.

R1 receivers can be used to control multiple heaters – up to 1955W. You will need to purchase an R1 for each heater or cluster of heaters. If you want to create separate heating zones in your home, you will also need to purchase an additional T1 for each separate zone. This allows you to accommodate the differing heating requirements of separate areas of the home without compromising comfort or energy efficiency.
