3.6 Control sequences
3.6.1 Sequences overview (setting via parameter P01)
The main control sequence (i.e. the water coil sequence of the fan coil unit) can be
set via parameter P01.
The following sequences can be activated in the thermostats (each without or with
auxiliary heating).
The available sequences depend on the application (selected via DIP switch, see
section 3.4).

see section 3.6.5:
– 4-pipe manual changeover (P01 = 2) means activating either cooling or
heating outputs.
– 4-pipe automatic changeover (P01 = 3) means swapping the control outputs
according to a heating / cooling sensor or remote switch
("main and secondary" application), see section 3.6.5.
For the relation between setpoints and sequences, see section 3.6.8.
