UNITS IN MULTIPLE CONFIGURATION
Complete system management is carried out by the
master 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
numerical order.
When the load decreases, the units are switched off
following the same sequence.
Example in cooling:
each unit turns on if:
Tw ≥ (se Tw_diff + 1°C)
each unit turns off if:
Tw ≤ (setpoint - 1°C)
At power on,
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
following the same sequence (first start, first stop).
If Tw < set point + 10°C

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.
Esempio in riscaldamento
Each unit turns on if:
Tw ≤ (setpoint - Tw_diff - 1°C)
Each unit turns off if:
Tw >= (se 1°C)
At power on, 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
following the same sequence (first start, first
stop).
If Tw > set point - 10°C

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
