This graph demonstrates how adjustments affect the heating and cooling curves of the ECM Modulator 4. You can raise and lower the minimum speed using the IAQ+ and IAQ- buttons. You can adjust the heating curve using the Heat Pump Jumper button (This Simulates using a Jumper in the heat pump terminals). You can also select the cooling ramp with the Humid Jumper button (Simulating a jumper in the Humid Terminals). When in humidity mode you can adjust the ramp with the Hum+ and Hum- buttons. Each click is equivalent to approximatly one full turn of a potentiometer.
