	nostic reset function that allows the controller to
	automatically recover after a high or low pres-
	sure cutout diagnostic. After 30 minutes the con-
	troller will reset the diagnostics. Most
	diagnostics occur due to intermittent water tem-
	perature or flow problem. The “smart reset” may
	eliminate many service calls.

Analog Inputs

The ZN510 controller has five available analog inputs (AI). These inputs are factory-configured for the following functions:

zZone = Space temperature.

zSet = Local setpoint.

zFan = Fan mode input.

zAI 1 = Leaving water tem- perature (Circuit 1).

zAI 2 = Discharge air tem- perature.

See Figure 8 for analog inputs.
