Multi-Zone is an advanced functionality of the ORIGINAL range of products that lets you heat each part of your home independently, in case of multiple energy sources (or heating circuits) in the same home.

If you have the most common case where a single boiler feeds one water circuit, with one device wired to switch it on, there's nothing specific to configure.

Find your setup

For more complex setups, a specific wizard has been designed and will pop up during the product installation so that you can describe how your system is built.

Follow the questions in the Wizard and answer simple questions:

• How many things can switch a heat source on (one boiler relay? two boilers? several zone valves?)

• Do your rooms share one water circuit or several?

After these questions, and if required, you will be prompted to assign heating devices to rooms it can control.

While the underlying logic can be tricky, the wizard is quite simple. Let’s take an example where you have :

• One heating system split into two zones controlled by motorised zone valves (electrovalves), e.g. an "upstairs" and a "downstairs" zone. On each electrovalve, you have a Thermostat that is able to turn the heating ON or OFF.

• In that case, you should assign all the rooms of the upstairs level to the Thermostat controlling the upstairs electrovalve and assign all the rooms of the downstairs level to the Thermostat controlling the downstairs electrovalve.

• You also need to assign all rooms to the Thermo Link that controls the final Heating system (in your basement, for instance) so that the system is able to finally turn the heating system boiler ON.

Remark: If two or more circuits overlaps in the same physical space (for instance a single large room warmed by both a radiator circuit and its own underfloor loop, or by two different boilers at once), in the app, split that one physical room into two rooms (for example "Living room – radiators" and "Living room – floor"). Then, assign each circuit's controller to its own room in the wizard. You keep independent control of both heat sources in the same space.

Energy type

At the end of the Wizard, you will also be prompted to choose the energy type for each controller (Gas, Electric, Air-to-air (heat pump), or Wood stove). Make sure you select the right type to have the best heating regulation possible.

Questions and troubleshooting

• What if I don’t know how many circuits you have? 
  Try to turn one heat source (or zone valve) on and leave the others off, then feel which radiators warm up. If only some rooms heat, those rooms are on a separate circuit. If every room warms up together no matter which control you use, you're on a single circuit. If you have any doubt, contact your installer.

• The wizard didn't appear after installation 
  That's expected if your home is in a simple setup with only one wired Heating Controller. In that case, everything is done automatically.

• A room I expected is missing from the wizard 
  The wizard only lists rooms that can ask for heat. If a room has no Radiator Valve and no Thermostat, it won't appear.

• The wrong controller starts when a room asks for heat 
  This means a room is linked to the heating device. Reopen the Wizard from the Settings (settings> home management> three dots upright> change heating device) and re-select the controller that is physically wired to that room's boiler or zone valve. Clear device names make this easier to spot.

• I already had older heating products before adding these 
  Existing products keep their previously defined energy type, and your new Original-range controllers are set up alongside them. If your new setup is simple, nothing extra is shown; if it's complex, you'll choose the energy type for each new controller on the final wizard screen.
