4.7 Control sequences
4.7.1 Sequence overview (setting via P001)
The main control sequence (water coil sequence of the fan coil unit) can be set via
P001.
The following sequences can be activated in the thermostats (with or without
auxiliary heating).
The available sequences depend on the application (selected via DIP switches,
see Application overview [ ➙ 37]).
Parameter P001 = 0 P001 = 1 P001 = 2 P001 = 3 P001 = 4

For manual changeover with 4-pipe applications, see 4-pipe fan coil unit [ ➙ 66].
● 4-pipe manual changeover (P001 = 3) means activating either cooling or
heating outputs
● P001 cannot be configured for applications with 6-port ball valve.
