Min: (0.0 to 70.0) Max: (50.0 to 130.0) The highest
and lowest percent of rated maximum speed that the
inverter will be allowed to drive the fan motor.
Min: (10.0 to 100.0) Max: (50.0 to 130.0) The highest
and lowest percent of rated maximum speed that the
inverter will be allowed to drive the fan motor when
heating is on.
Min: (10.0 to 100.0) Max: (50.0 to 130.0) The highest
and lowest percent of rated maximum speed that the
inverter will be allowed to drive the fan motor when
cooling is on.
Min: (10.0 to 100.0) Max: (50.0 to 130.0) The highest
and lowest percent of rated maximum speed that the
inverter will be allowed to drive the fan motor when
dehumidification is on.
(0.0 to 20.0) The increment, in percent, by which
variable speed is increased when called for by an
increase in load.
(0.0 to 20.0) The decrement, in percent, by which
variable speed is decreased when called for by an
decrease in load..
(List box:)
0-5 Volts: Sets the RTC board's analog output for a
variable speed drive requiring 0-5 volts.
0-10 Volts: Sets the RTC board's analog output for a
variable speed drive requiring 0-10 volts.
(1 to 20) This setting together with the next regulates
the sensitivity of speed control. These should be left at
the default settings and should only changed by a
Danfoss-trained technician.
(1 to 15) This setting together with the preceding one
regulate the sensitivity of speed control. These should
be left at the default settings and should only changed
by a Danfoss-trained technician.
(0 to 10) The number of reset attempts, when proof is
not detected, before the variable speed drive will be
placed in override.
(0 to 600) The number of seconds that must elapse
between resets.
(0 to 600) The number of seconds that must elapse
after proof is not detected, before a reset attempt.
(List box: Yes, No) Whether or not phase loss will be
monitored.
(List box: Yes, No) Whether or not the unit is to be
shut down when its phase loss detector input is on.
