These are the same as above except that
they apply to Duplex models for the "COOL"
zone of Heat/Cool applications or for the
second set of PID constants.
CYC T1 or

1 to 120
CYCLE TIME (HEAT) determines the length
of one time proportional output relay cycle.
Defined as "HEAT" cycle time for Heat/Cool
applications.
CYC T1—Electromechanical relays
CT1 X3—Solid state relays
ATTENTION Cycle times are in either
second or 1/3-second increments depending
upon the configuration of RLYTYP in the
Output Algorithm Set Up group.
CYC2T2 or
CT2 X3
109
1 to 120
CYCLE TIME 2 (COOL) is the same as
above except it applies to Duplex models as
the cycle time in the "COOL" zone of
Heat/Cool applications or for the second set
of PID constants.
CYC2T2—Electromechanical relays
CT2 X3—Solid state relays
ATTENTION Cycle times are in either
second or 1/3-second increments depending
upon the configuration of RLYTYP in the
Output Algorithm Set Up group.

SECURITY CODE—The level of keyboard
lockout may be changed in the Set Up mode.
Knowledge of a security code may be
required to change from one level to another.
This configuration should be copied and kept
in a secure location.
NOTE: The Security Code is for keyboard
entry only and is not available via
communications.
ATTENTION Can only be changed if
LOCK selection is NONE.
LOCK 111
LOCKOUT applies to one of the functional
groups: Configuration, Calibration, Tuning,
Accutune. DO NOT CONFIGURE UNTIL
ALL CONFIGURATION IS COMPLETE.
NONE 0
NONE—No lockout; all groups are
