STEP

Air Handler

REQUIRED WIRING

• Refer to Field Hook-up Diagrams.

• 4TTX6/4TWX6/4A7A6/4A6H6 units require 80% airflow with “Y1”

(firststage), 100% airflow with “Y2” (second stage).

Note A –

 The installer must jumper at the LVTB “R” to “O”.

Note B –

 Cut/remove the factory installed “BK” jumper.

• Connect “Y1” from thermostat to “Y/Y2” at VS Air Handler to “Y1” at

Outdoor Unit.

• Connect “Y2” from thermostat to “BK” at VS Air Handler to “Y2” at

Outdoor Unit.

FIELD WIRING

Notes:
1. ODT-B must be set lower than ODT-A.
2. If ODT-B is not used, connect A Jumper wire from W3 to W2. If ODT-A is
not used, connect a jumper wire from W2 to W1.
3.  If electric heat does not have 3rd contactor (CH), connect a jumper wire
from W3 to W2. If electric heat does not have 2nd contactor (BH), connect a
jumper wire from W2 to W1.
4. X2 must be connected to variable speed air handler terminal W3, as
shown, for proper indoor air flow during the defrost cycle.
5. Connect only if used with applicable indoor thermostat.
6. When heaters are used, discard power leads with polarized plug PM-A and
connect 1-PF to mating plug in the heater control box as shown.

REQUIRED WIRING

• Refer to Field Hook-up Diagrams.

• 4TTX6/4TWX6/4A7A6/4A6H6 units require 80% airflow with “Y1”

• Connect “Y1” from thermostat to “Y/Y2” at VS Air Handler to “Y1” at

Outdoor Unit.

• Connect “Y2” from thermostat to “BK” at VS Air Handler to “Y2” at

Outdoor Unit.

Notes:
1. Be sure power supply agrees with equipment nameplate.
2. Power wiring and grounding of equipment must comply with local codes.
3. Low voltage wiring to be No. 18 AWG minimum conductor.
4. If outdoor thermostat (ODT) is not used, connect W2 to W3.
5. Be sure the jumper between “R” and “BK” is cut or removed
(See Note B below).
6. With “O” and “Y/Y2” energized, indoor fan is at 80% airflow.
7. With “O”, “Y/Y2” and “BK” energized, indoor fan is at 100% airflow.
8. When heaters are used, discard power leads with polarized plug PM-A and
connect 1-PF to mating plug in the heater control box as shown.
