Proportional Output Signal Operation: At 3 F degrees from setpoint either the heat or
cool output signal goes to 10 Vdc, based on ambient temperature being above or
below setpoint. As the ambient temperature starts to move closer to setpoint the
output signal remains at 10 Vdc until ambient temperature is within 2 F degrees of
setpoint. Then the output signal starts to modulate, as the ambient temperature
comes closer to setpoint, the output signal decreases. Then the output signal will
modulate up or down based on the ambient temperature and this modulation will
continue until setpoint is achieved, at which point the output will be 0 Vdc.
