AVS Electrical Connections and Air Flow
The variable speed AVS Series air handler control board and field wiring diagram are illustrated in
Figure 1.
Figure 5. AVS Series Air Handler Control Panel and Field Wiring
The blower speeds can be adjusted by changing the jumper settings on the control board as appropriate.
Heat and Cool panels: “A” is the highest speed and “D” is the lowest speed.
Adjust panel: “NORM” is the normal airflow. “+” is more airflow. “-“ is less airflow.
Test panel: NOT FOR FIELD ADJUSTMENT. FOR FACTORY USE ONLY.

Thermal Bulb and Field Conversion
The air handler is shipped from ETI as it was ordered, either for vertical or horizontal installation. Figure 8
illustrates an air handler shipped from the factory with the TXV thermal bulb attached to the suction tube.
Figure 8. Air Handler and Thermal Bulb as shipped
AVS-410CH-IM (10/13) Page 8
The thermal bulb must be located and clamped to a HORIZONTAL extension of this suction tube,
with options for the suction tube extension illustrated in Figure 9. This shows the suction tube directional
options for an air handler that is to be installed in the VERTICAL direction.
Figure 9. Horizontal Suction Line Options – VERTICAL Air Handler Installation
AVS-410CH-IM (10/13) Page 9
Figure 10 illustrates locating the thermal bulb on the suction line extension. It shall be located at least 6
inches downstream of any fitting or bend in the suction tube extension, and at the 3:00, 4:00, 8:00 or
9:00 o’clock positions.

AVS-410CH-IM (10/13) Page 10
Clamp the thermal bulb firmly against the clean suction tube extension and parallel to it, as shown in
Figure 11, to ensure good thermal contact along the entire length of the thermal bulb.
