PROPORTIONAL BAND 2 or GAIN 2, RATE 2, and
RESET 2 parameters are the same as previously
described for “Heat” except that they refer to the cool
zone tuning constants on duplex models or the second
set of PID constants, whichever is pertinent.

CYC SEC
1 to 120 seconds
CYCLE TIME (HEAT) determines the length of one time
proportional output relay cycle. Defined as "HEAT" cycle
time for Heat/Cool applications.
 Electromechanical relays
CYC2 SEC
1 to 120 seconds
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 second
set of PID constants.
