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).

Parameter P01 = 0 P01 = 1 P01 = 2 P01 = 3 P01 = 4

Note:

1) For chilled / heated ceiling and radiator applications, see section 3.6.6;
for compressor applications, see section 3.6.7.

2) For manual and automatic changeover with 4-pipe applications,
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.
