Sequences overview (setting via parameter P01)

The sequence can be set via parameter P01, if available.
The thermostats can be used in systems featuring:
· Heating only (P01 = 0)
· Cooling only (P01 = 1)
· Manual heating/cooling changeover (P01 = 2)
· Automatic heating/cooling changeover (P01 = 3)
· Heating and cooling mode (e.g. 4-pipe system) (P01 = 4)
The available modes depend on the application
(selected via DIP switches, see section 4.5).
