CURD
CURRENT DUPLEX — is similar to current simplex but uses a second
current output. The second output is usually scaled so that zero and span
correspond with 0 % and 50 % output (cool zone). When the output is 0 %
to 50 %, the controller uses tuning parameter set #2, when the output is
50 % to 100 % it uses set #1.
Other prompts affected: 4-20RG
CURT
CURRENT/TIME DUPLEX — is a variation of duplex with current
active for 0 % to 50 % output (tuning set 2) and time is active 50 % to
100 % output (tuning set 1). Relay controls heat, current controls cool.
Other prompts affected: 4-20RG
TCUR
TIME CURRENT DUPLEX — is similar to CUR TI except that current is
active for 50 % to 100 % and time is active for 0 % to 50 %. Relay controls
cool, current controls heat.

12.2.61 OUT Hi
This prompt is part of the Control Set up group.
This is the highest value of output beyond which you do not want the controller automatic
output to exceed. Use 0 % to 100 % for time proportional output type.
Range of Setting:
12.2.62 OUT Lo
This prompt is part of the Control Set up group.
This is the highest value of output below which you do not want the controller automatic
output to exceed. Use 0 % to 100 % for time proportional output type.
Range of Setting:
12.2.63 PARITY
This prompt is part of the Communications Set up group.
PARITY pertains to the use of a self-checking code employing binary digits in which the
total number of ONE's (or ZERO's) in each permissible code expression is either
ODD or EVEN.
