11 QuestionsQ: The Rc and C terminal on the back.....what are they for? Does a jumper wire need to be connected to these two terminals??

Verified Reply- PexSupply StaffThe Rc terminal is for 24VAC power from cooling transformer. The C terminal is known as the "24VAC common" and it is used for 2 transformer systems (use common wire from cooling transformer). The jumper will have to be connected to the C terminal if you have 2 - 24VAC transformers in the system. If you only have one transformer, the jumper cable that comes pre-installed will have to be removed.
This is spelled out in the installation manual at http://s3.pexsupply.com/manuals/1249544874360/Honeywell_TH5110D1022_Install_Guide.pdf The short answer is that the Rc and C terminals should not be jumpered together. The C terminal is used if you want to power the thermostat off the transformer in the air handler and not use batteries.
If you have only one control transformer, yes. When all else fails, play close attention to the details in the instructions. Factory default settings probably apply to most installations.
