6.3| Connection of setpoint sequences
To facilitate interconnections among sequences, it is possible to automatically make one sequence start when the
preceding one is at 100% and to make it use automatically the same control probe. The probe used is the one used
by the preceding sequence.
When selecting the setpoint for a sequence (D02, H12, H22, C12), set it to the reference of the preceding sequence,
using the following values:
FRH
: connection to the Freeheat Sequence. Possible for all the sequences.
FRC
: connection to the Freecool Sequence. Possible only for Cool Sequence 1.
HS1
: connection to the Heat Sequence 1. Possible only for Heat Sequence 2
In the next figure you can see the result of the following settings:
H12=FRH: setpoint of the Heat Sequence 1 connected to Freeheat Sequence
H22=HS1: setpoint of the Heat Sequence 2 connected to Heat Sequence 1
C12=FRC: setpoint of the Cool Sequence 1 connected to Freecool Sequence
The control probe is forced for all the sequences to the one used by dampers.

In the next figure you can see the result of setting D02=FRH: setpoint of Freecool Sequence connected to the
Freeheat Sequence.
