Temperature Setpoint Zone Designation Table
The following table shows the setpoint designations in
output instance 2 used to command the Therm-O-Flow
temperature zones to the corresponding setpoint. Prior
to writing to instance 2, the PLC needs to write the
desired temperature setpoint (in tenths of a degree for
the selected temperature unit of measure) to output
instance 3 for the selected zone. After the zone desig-
nation has been written, the PLC can monitor the set-
point change by monitoring the correct setpoint
indications: input instances 15-28 or 32-45.
