TPSC = Three Position Step Control
N/A = Not Available – This output algorithm type cannot be performed with this Output 1/2
option.
INU = I
nstalled, Not Used – The installed Output 1/2 option is not used for the configured
output algorithm type.
Not Needed = Auxiliary Output is Not Needed to provide the desired output algorithm and
can be used for another purpose. With the proper configuration, Auxiliary
Output could also be used as a substitute for the Current Output.
* To obtain this output algorithm type with these Output 1/2 Options: 1) Configure the
OUTALG selection as “TIME D”; 2) Configure Auxiliary Output for “OUTPUT” and; 3)
Scale the Auxiliary Output as necessary for the desired output algorithm type. For these
selections, the Output 1 (HEAT) and Output 2 (COOL) signals will be present both on the
Auxiliary Output and on the two relays normally used for Time Duplex.
