RPM Mode
RUNNING/ FAN STATUS
CONTINUOUS LOOP
Displayed when:
1) No error codes are present
2) Motor has completed ramping

Indicates the current rpm of Motor 1 in the system. “0” rpm
here indicate that no fan speed has been requested.
→

Indicates the current rpm of Motor 2 in the system. “0” rpm
here indicate a fan off condition OR a fan “missing”
condition
(a)
.
→

Indicates the status being calculated or Fan Motor 1. If “off,”
this indicates that either:
1) No fan speed is being requested or
2) The fan performance is failing to meet the request; refer
to “Troubleshooting (ECM),” p. 103 for additional
information.
If “on,” this indicates that the fan is performing correctly and
will be used to report fan status correctly, depending on
 mode.
/

Indicates the status being calculated or Fan Motor 2. If “off,”
this indicates that either:
1) No fan speed is being requested or
2) The fan performance is failing to meet the request; refer
to “Troubleshooting (ECM),” p. 103 for additional
information.
3) If the target speed for Motor 2 is “0”, this is used to
indicate a missing motor
(a)
.
If “on,” this indicates that the fan is performing correctly and
will be used to report fan status correctly, depending on
 mode.
/

Indicates that the temperature sensing circuit has
calculated a logical “on” based on the settings of the
following parameters:
///
(a)Motor 1 is the only motor for all horizontal unit ventilator sizes (075, 100, 125, 150, 200).
