All motor times are approximate.
At start up, the motor runs at 82% of air flow for 7.5 minutes, then ramps up to 100%
At shut down, the motor runs at 94%of air for 60 seconds before a 30 second ramp off.
Continuous fan is 31% of total CFM−transition time from continuois fan to heat/cool air flow is 20 seconds.
SPEED CHANGES:
To increase COOLING CFM by 5%: Cut violet wire (PIN 5) to motor and tape off ends.
To increase HEATING CFM by 5%: Cut pink wire (PIN 11) to motor and tape off ends.
The above changes will increase the continuous fan speed to 620 CFM.
HUMIDITY CONTROL
The CFM of the motor can be reduced by 15% by wiring a standard humidity contol in series with the TAN (PIN 10) wire. The humidity control
must be closed when the humidity is below its setpoint and open when the humidity is above its setpoint. When the humidity control opens,
R is interupted to PIN 10 and the CFM is reduced 15% from full speed.
