MD1 Wired Thermostat – best for new builds / renovations and commercial applications

Use one MD1 per room / zone and wire all heaters within the room onto the same circuit.

MD1 is wired to the mains electricity supply & requires recessing into the wall.

This is the best option for new builds or renovations where cabling runs can be hidden in walls / ceilings.

Can become App-enabled by adding the Herschel iQ hub (optional).

T1 Wireless Thermostat Pack – versatile solution which minimises cabling / disruption

Use one T1 per room / zone and one R1 per heater. Each R1 requires mains electricity supply.

Wirelessly pair each R1 to the T1.

The T1 can be located anywhere in the room and is battery operated so does not require mains supply. Can be surface mounted to the wall or placed on a shelf. A great retrofit option minimising disruption to walls / ceilings because R1 can be located close to heater.

Can become App-enabled by adding the Herschel iQ hub (optional).

R1 + iQ Hub – Slick App only control

Wire all heaters on the same circuit to the R1 (up to 2kW per R1). Requires a minimum of one R1 per room / zone.

Program and control the heaters using the APP only.

Note: the R1 will sense the room temperature which will be displayed on the APP. Must be used in conjunction with the iQ Hub.

This is a good option where heaters are ceiling mounted and cabling can be run in the ceiling void with the R1 positioned on the ceiling or wall.

WH1 Central Controller

Our WH1 Controller system offers a local centralised control solution. Control all your heaters in the property from one colour touchscreen unit. Heaters are controlled wirelessly without the need for wifi. Choose this option if you want the benefits of centralised control but do not need to control remotely or do not have wifi.

Each R1 receiver pairs with the WH1 and you can program each R1 to run its own 7 day program or run in Away or Comfort modes.

Up to 36 R1s can be added to a single WH1 and allocated to 6 different zones (6 R1s per zone).

Note: The WH1 system is unable to be app-enabled.
