NOTES:

1.620 ohm, 1 watt 5% resistor should be removed only when using differential enthalpy or dry bulb.

2.If a separate field-supplied 24 v transformer is used for the IAQ sensor power supply, it cannot have the secondary of the transformer grounded.

3.For field-installed remote minimum position POT, remove black wire jumper between P and P1 and set control minimum position POT to the minimum position.
