Series Switchback
If the electronic compressor controller fails,
its normally closed contacts remain closed and
compressor cycling falls to the control wired
between P1,1 and P1,2.
A Time Delay Split (TDSP) prevents all the
compressors from coming on at once on start-
up after the control panel has been off.
