Communication for SA BUS devices

EconCtrlr parameter reports UCB-to-economizer board SA BUS 
communication status. Positive of the VDC (typically, a 
fluctuating 1.5 to 3.5 volts reading to C; at least 0.25 volts lower 
than +) SA BUS communication circuit to the UCB. Through the 
unit wiring harness, may continue on to the 4-stage board and/or
