Have an American Standard Heat Pump and wanted to replace the stock thermostat with a Honeywell CT3611 to save some energy.
Can read a diagram, but the CT3611 calls for a connection on the L connector from either the L or F on the old thermostat. Problem is I don't have one. It states that it is a system monitor. I have a T-tan wire from the old thermostat that I need to tape up. Do I need the L connection?
Of course the Honeywell help desk is closed on the weekend when I try to do the job.
Thanks in advance.
