4.7.2 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 mode (P01=0)
• Cooling only mode (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 switch, see section 4.5).
Parameter P01 = 0 P01 = 1 P01 = 2 P01 = 3
