How many independent zones can I manage through the control unit software?

You can use all 40 climate zones with the automatic timer-thermostat function. These areas must be set as Centralised zones, associating each climate-zone with a group in the Climate menu . Then you can create daily schedules, time slots, with three different temperature levels settable for each time slot (T1 is the lowest temperature desired in the space, while T2 and T3 are two higher temperature levels that can be set at will during the day).
