12.2.26 CYC2T2 or CT2 X3 (CYCLE TIME2 - COOL)
This prompt is part of the Tuning Set up group.
CYCLE TIME2 (COOL) determines the length of one time proportional output relay
cycle. Defined as “COOL” Cycle time for Heat/Cool applications.
CYC2TI—Electromechanical relays (seconds)
CT2X3—Solid state relays (1/3 seconds)
Cycle times are in either second or 1/3-second increments depending upon the
configuration of RLY TY in the Output Algorithm Set Up group.
Range of Setting: 1 to 120
ATTENTION
If 1/3 second increments are used, 1 = .33 seconds and 120 = 40 seconds.
12.2.27 DBAND (DEADBAND)
This prompt is part of the Control Set up group.
DEADBAND is an adjustable gap between the operating ranges of output 1 and output 2
in which neither output operates (positive value) or both outputs operate (negative value).
It is the difference between the nominal trip points of relays 1 and 2.
Shows when only Time Duplex or Three Position Step is selected.
Range of Setting: -5.0 to 25.0 % (Time Duplex)
0.5 to 5.0 % (Three Position Step)
12.2.28 DECMAL (DECIMAL POINT LOCATION)
This prompt is part of the Input 1 Set up group.
This selection determines where the decimal point appears in the display.
