Using Analog Output for Heating and Cooling
This feature is typically set up at the factory, but it can also be installed as a retrofit in the
field. It is used to control a modulating valve or heating SCR proportionally. The analog
signal can be configured to be 0-20mA, 4-20Ma, 0-5VDC, 1-5VDC, 0-10VDC, and 2-
10VDC. Inserting the card into header “J5” for cooling or “J6” for heating automatically
configures the controller to direct its outputs through these boards.
Use the following procedure to set up the analog outputs:
1. Insert the analog card (P/N 691-00537-00) into the appropriate header.
2. Press the Index button two times to access the Secondary menu.
3. Press the Enter button.
4. Press the Index button until the display reads “Cool Output” or “Heat Output.”
5. Use the Up and Down buttons to select the analog signal type.
6. Press the Enter button to accept the value.
7. Press the Alarm Silence button to return to Running mode.
