Microprocessor-based instruments require a “clean” source of power that is steady and free of
noise. Electrical noise may be caused by line faults, power switching, motors, motor controllers,
or power controllers containing SCR devices. Without a clean source, any microprocessor is
prone to failure. If your power source is not from a clean line, your system can be protected by
installing a line filter.
Where external contactors or solenoids are used with relay output instruments, an R/C Snubber
Network should be used. The snubber installs easily directly across the field coil terminals of the
relay or solenoid.
Do not run thermocouples, RTD’s or other class 2 wiring in the same conduit or area as the
power leads. Maintain separation between wiring of sensors, process signals and other power
and control wiring.
3-2 Making Electrical Connections
Wire up per applicable electrical schematic.
3-3 Location
Mount the instrument in a location that will not be subject to excessive temperature, shock or
vibration. All models are designed for mounting in an enclosed panel.
When properly mounted in an enclosed panel using a gasket at the panel/controller interface,
the keypad can be washed down with water. Do not use high-pressure fluids.

header J6 initiates the start sequence. The display flashes MODE IS OFF, PRESS START
TO RUN. THE VENT/FILL timer counts down from 10 minutes. After the VENT/FILL
timer has elapsed, the controller will automatically go to the second vent operation for 10
minutes. Upon completing the second vent operation the controller will automatically go to
the run mode.
The controller may also be started or stopped locally by depressing the controller start button
or stop buttons.
4-4 Tuning
Autotuning
The factory default for the controller is automatic half/full heat for water units,
and full heat for oil units. If an autotune cycle is completed, do not switch to
low heat without performing a new autotune cycle. Failure to autotune will
result in poor control of the process. Subsequent changes from one heat setting
to another require autotune to be run.
The Tune button is used to toggle the autotune process. If no autotune operation is
in
progress,
pressing the Tune button starts the autotune operation. The “AutoTune” message is
displayed on the LCD. If an autotune operation is already in progress, pressing this button
again will immediately stop the autotune operation. The display will return to the “Running”
message.
During the autotune process, the control point is the ‘To Process’ probe or the ‘Remote
Selected’ probe. The tuning constants (i.e. rate, reset and gain) can be altered in setup mode.
The unit’s cycle time is selectable in one-second increments. The heat and cool cycles have a
minimum pulse of one second.
