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.
