The multi-zone kits includes all of the contents of the base kit, plus actuators, one thermostat and a wiring centre. This provides you with everything you need to heat a single area, either as one room or multiple rooms under one controller. Each multi-zone kit includes one thermostat required to control the system- if you prefer a different model you can pick one that suits your taste from a selection of hard wired, wireless and app controlled models.
If you want to control the heating separately in different rooms, you need to add additional thermostats to the kit. Remember- with an independently controlled multi-zone heating system you’ll need one thermostat in each room!
