Air Handling seq. - user manual
It is possible to congure more coils controlled with the same control sequence. In this case they share equally the
control band.
* Three coils for heating
controlled with Heat Sequence 1;
b10=b40=b70=HS1

4.2| Coil output management
The following parameters set the way coil output are managed according to the load demand calculated by the
associated temperature control sequences (see “6.2] Heat and cool control sequences”).

Tab 10_ [Coils control -Coil output management]
Through b11, b41, b71 you can dene the actuator type for each coil, whether it is a water coil controlled trough a
valve or it is a step controlled coil (e.g. electric resistances). In this case there are 3 possible way of control: linear step
switch, variable step switch binary step switch.
