Time Current Time Current Duplex is similar to Current Time
except that current is active for 50 % to 100
% and time is active for 0 % to 50 %. Relay
controls cool, current controls heat.

Current Time, or Time Current
50 Percent Current Duplex Range (Split)—This setting
should be 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:
l
AUX OUT in the Options Set Up group must
be selected for Output.
l
The Auxiliary Current Output is scaled as
desired for 0-50 % controller output.
l
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
111
