With 4 hot air generators in cascade control and a
differential of 5, the first hot air generator is
switched on as soon as the demand exceeds 5%,
the second hot air generator when the demand
exceeds 30% (100/4+5), the third when the
demand exceeds 55% and the fourth when the
demand exceeds 80%. The switch-off is done in
reverse logic, the fourth hot air generator is
switched off at 70%, the third at 45%, the second
at 20% and the first when the demand drops below
the setpoint plus differential. The percentage is
applied to all slaves.
The function "ROTATION INSER. SLAVE" is
currently not available. Activating or deacti-
vating this function does not affect the units.
