some of ours techs have ran into the peak saver tstat. Is there a wiring diagram of how these are set up that any one has?
oh aren't these t-stats fun!
The last time I saw one it was wired this way,
Relay terminal #1 goes to R on control board.
Relay terminal #3 goes to outdoor AC unit. (remove Y from the furnace and connect to relay.)
Relay terminal #4 goes to Y on control board.
Relay terminal #5 goes to C on control board.
