has the ability to accept different

types of demand signals from either an energy

management system or a humidistat. Follow these

steps when a signal change is needed:

1. Remove the old signal wires from the board

(terminals 21, 22 and 23).

2. Refer to program code nomenclature on Pages 8

and 9. Refer to: “K. Type of humidity sensing

device” to identify the new signal that is needed.

3. Enter the “Set Up” screen on the

VAPOR-LOGIC

keypad and scroll to the

“Configuration String” screen.

5. Adjust the shunt connector J17 to the proper

signal type, if necessary:

– If the signal is current, the jumper should be

on I.

– If the signal is voltage, the jumper should be

on V.

– If the signal is resistance, the jumper should

be on R.)
