0.750 IWC
For test purpose a 290 ohms resistor shall
be used as the switch load (wire switch per
manual instructions or figure above).
Press the Up or Down arrow until .200 is
displayed or apply .200 IWC.
Output 2 switch in normal state (OFF).
Place voltmeter leads across resistor and
verify voltage reading (0 V dc).
Press the Up arrow until .750 is displayed or
increase pressure up to .750 IWC.
Output 2 switch turns ON (Out 1 is ON since
differential pressure reached .500 IWC).
Verify voltmeter reading (28 VDC).
External relay energizes.
Relay normally closed switch opens,
heating/cooling system shuts down.
Press the Down arrow until .200 is displayed
or decrease pressure to .200 IWC.
Verify voltage reading (0 V dc).
Switch changes to normal state (OFF).
