- Has an unstable demand (contactor pulling in and out), decrease your proportional band (PB)
value or increase your derivative gain (DG) value. Decreasing your PB value will help reach a sta-
ble demand, but it will increase the time it takes to reach the desired RH. Another solution to fixing
an unstable demand is to increase the DG value. However, if you have any noise in your demand
signal, increasing the DG value will only make your unit demand act worse. If this is the case you
should decrease the DG value.
