12. WCC III INSTALLATION
If you want to test the ramp speed, disconnect all wires from the
“HEAT,” “COM1,” “COOL,” and “COM2” terminals and use a
volt meter to measure the DC voltage between “ANALOG OUT”
and “GND” as you jumper test point #4 (TP #4) to ground.
The voltage should increase from the minimum to the maximum
voltage during the set time interval. Then, remove the jumper from
“TP #4” and jumper “TP #5” to “GND.” The voltage between the
“ANALOG OUT” and “GND” terminals should decrease from the
maximum to the minimum voltage during the set time interval.
