START-UP
Complete system management is carried out by the mas
-
ter unit, identified by address 0.
Thermoregulation takes place on the supply temperature
of the entire system (Tw).
At switch-on, when a load is requested, the units are
switched on in sequence based on their address, in nu
-
merical order.
When the load decreases, the units are switched off fol
-
lowing the same sequence.
Example in cooling:
If Tw >= set point + 10 °C
•
the control activates 50 % of the resources in sequence
based on the set address.
•
after a time interval (default: 240 seconds)
•
if the load increases, additional resources are activated
•
if the load decreases, the units are switched off follow
-
ing the same sequence (first start, first stop).
If Tw < set point + 10 °C (in cooling)
•
the control activates only the master unit.
•
after a time interval (default: 240 seconds)
•
if the load increases, additional resources are activated
based on the set address
•
if the load decreases, the master unit switches off.
