Control Mode
CONTROL Mode is similar to OBSERVE
mode, except that you decide what signals you
would like sent down to the motor electronics.
The MODE LED glows RED in this mode.
The CONTROL mode is used for further di-
agnosis, and also to test various settings for
problems without having to reset the system
thermostat. Detecting the RPM and CFM of
the various modes that a system can be set
to is best accomplished here. Please remem-
ber that the Digital Display may take as much
as 30 seconds after the motor has reached a
constant speed to stabilize. Be patient.
The OPTION STEP switch selects one or
more options. It selects the options in a circle;
that is, they repeat after the end of the list.
Initially OFF, repeatedly pressing the up switch
turns the R. VALVE option line on; then the
HUMID. line; then BOTH; then back to OFF;
and then starts over again. You can use ei-
ther UP or DOWN to get to your choice quickly.
