6.7 Cooling and Heating Regulations
When the primary regulation is made on the valve (PG04=1) it is possible to manage and to
regulate the command for the cooling /heating valve.
The regulation comes on a flowing Set Point calculated as shifting from the regulation
ambient temperature Set Point. The valve is commanded using a proportional algorithm (P),
or a proportional integral (PI). The reference probe is that of the delivery temperature.
Note. With the unit running on a single coil, enabling the valve will depend on the type of
primary regulation that is chosen. If the parameter PG04=0, primary regulation on the fans,
the valve remains disabled. In order to utilize you will need to set PG04=1 (primary
regulation on the valve).
6.7.1 Set Point flowing from delivery
If the delivery temperature probe is present it is preferable to use an algorithm which, in
relation to the shifting between Set Points and ambient temperatures, stabilizes the
temperature value required for air delivery and thus effects the action of the regulation
module on the valve. The delivery set Point is calculated like the flowing Set Point on the
ambient temperature.
The Minimum Limit and the Maximum Limit are expressed as the difference (Pb05) in
temperature with respect to SEtC (SEtH, if single Set Point), ambient regulation set Point.
The neutral zone is the same zone which is set for the regulation of the coils on the delivery
temperature.
Note. Setting Pb05=0.0 the function is as if it were disabled; in this case the Delivery Set
Point coincides with the Ambient Set Point.
