Parameter Definition
used for Relay/Current and Current/Relay Duplex Outputs. It can
also be used for Current Duplex when an Auxiliary Output board is
present. This enables the normal control current output to provide
heat control and the auxiliary current output to provide cool control.
To enable this:
• AUX OUT in the Options Set Up group must be selected for
Output.
• The Auxiliary Current Output is scaled as desired for 0-50 %
controller output.
• Deadband for this configuration only applies to the Current
Output. The Auxiliary Output must have the Deadband scaled in.
FOR EXAMPLE:
If a 2 % Deadband is desired, then enter 2.0 for the Deadband
selection in the Control Algorithm group. This will apply Deadband
to the Current Output. In the Options group, set the Auxiliary
Output LOW VAL selection to 49.0 and the HIGH VAL selection to
0.0.

CURRENT DUPLEX RANGE (FULL) enables the Current Output
to provide both heat and cool functions for control over 0-100 % of
the controller output. The PID heat parameters apply when the
output is greater than 50 % and the PID cool parameters apply
when the output is less than 50 %. The second current output is
not required for this type of duplex operation.

DIGITAL OUTPUT STATUS AT 0 % OUTPUT allows the following
selections:
1OF 2OF Output 1 de-energized
Output 2 de-energized
1ON 2OF Output 1 energized
Output 2 de-energized
1OF 2ON Output 1 de-energized
Output 2 energized
1ON 2ON Output 1 energized
Output 2 energized
RLY TYPE
RELAY CYCLE TIME INCREMENT selection is used only for Time
Simplex and Duplex output configurations. This configuration sets
the increment size of the relay cycle times in the Tuning and
Tuning 2 Set Up groups.
MECHAN
ELECTROMECHANICAL RELAY—Cycle time in one-second
increments.
SOL ST
SOLID STATE RELAY—Cycle time in 1/3 second increments. This
is useful for solid state relay applications that require shorter cycle
times. DO NOT use this setting unless cycle times of less than 1
second are required.
ATTENTION The Lockout selection must be set to NONE in order
to view this selection.
