HOA Menu

The HOA (Hand-Off-Automatic) Menu is used to quickly and easily test all relay outputs, and to stop or enable
automatic control.
Touch the relay number in order to change the HOA state of that relay. The relay number will be shaded dark, and
its current HOA state will be shaded dark. Then touch the desired state. The change happens immediately unless
that relay has a Minimum Relay Cycle programmed that is above 0 seconds.

Graph Menu

The Graph Menu is used to display a graph containing one sensor or analog input value plus one digital input or relay
state. Touch the Graph icon and the controller will display "Generating Graph Please Stand By" for a few seconds
then show the graph. The default is to show the value of sensor input S11 and the state of relay output R1 over the past
10 minutes.
Touching any point on either line on the graphs displays a vertical line plus the details for that data point: date and
time, value of the sensor, and an arrow showing if the state or the digital input/relay was high or low at that time.
Touching the or the
of one time range. It can only go back in time to the point where the data log file used to generate the graph starts.
Changing the time frame while in the graph view, after moving back in time, shows data from that past time. Exit-
ing the graph menu and returning to the graph menu moves back to the current time.

The graph auto-scales based on the sensor value if both Low and High Axis Limit are set to
0. To manually adjust the Y axis scale, enter the low limit here.
