Multi-speed Odyssey ™ units are electromechanical
and do not require configuration jumpers.
Adjusting Maximum Unit Airflow
Multi-speed (two speed) and SZVAV Odyssey ™ split
systems have a fixed motor pulley. Maximum and
minimum airflow adjustment is accomplished by
changing the frequency output of the air handler VFD
(parameter 6-14) using the provided VFD keypad. Refer
to the unit IOM for specific instructions on airflow
adjustment.
SZVAV air handlers use a combination of adjusting the
R-136 potentiometer on the RTOM (similar to
Precedent
™ ) and frequency parameter adjustment in
the VFD. Refer to the unit IOM for specific instructions
on airflow adjustment.
SZVAV, Multi-Speed and 17 Plus
Unit Outdoor Air Compensation
and Economizer Minimum
Position
Because of the need to maintain the same outdoor cfm
during different fan speeds, set up of the economizer
minimum position is different than for constant volume
units.
There are 3 speeds and damper positions to set up,
LOW, MEDIUM, and HIGH.
