ECONOMIZER NOTES:
1. 620 ohm, 1 watt 5% resister should be removed only when using differential
enthalpy or dry bulb.
2. If a separate field supplied 24v 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.
