Note: For all of the service test steps in which the fan speed output is at "MIN", the fan speed will
be at the minimum speed for the associated step.
(a) 17 SEER units cannot be configured as heat pumps.
(b) For units configured with two steps of mechanical cooling, the unit will energize the supply fan and ramp the output up to 100% for the associated "Cool 2"
step in service test.

(a) 82% chosen in order to give the user the ability to have a Service Test step for setting up proper OA damper position setpoints.
(b) For units configured with two steps of mechanical cooling, the unit will energize the supply fan and ramp the output up to 100% for the associated "Cool 2"
step in service test.
(c) 17 SEER units cannot have 3-step cooling.
(d) Reheat step only performed on units configured for HGRH, not for enhanced dehumidification only.
