Setting Up Analog Outputs
Sensing Point Outputs
menu level 2.2.1
Channel
1=Chan 1 2=Chan 2
After selecting a channel, the menu automatically provides new
selections to assign sensing points.
Sensing Points
1=Add All Heads 2=Add Head 3=Del All Heads
4=Del Head 5=View Assigned 6=Save
An "X" will mark on the display to show which sensing points are assigned
to the selected channel. To keep changes, user must save assignments.

Setting Up Relays
Relays 1 and 2 can be set as switch points or test/status parameters. If relays 1 or 2 are used for switch
points, their mode must correspond to their respective analog output channels. (e.g. If relay 1 is set to
be a flow switch point, then analog output channel 1 must be in the flow mode.) If relays 1 or 2 are set
to flow or temperature modes, the user MUST set switch point and hysteresis parameters. If this is not
done, a chattering noise will be heard. Relay 3 and 4 can only be set as test/status parameters.
Relay Mode
