12 Review your answer from Step 6.
Set the R-switch up or down based on your
wiring notes in Step 6.
If there is only one wire connected to R,
then your system uses this wire to power
both heating and cooling. Set the R-switch
to the up position.
If you have an R or Rh, and Rc wire, then
your system uses R or Rh to power the
heating system and Rc to power the cooling
system. Set the R-switch to the down
position.
NOTE: U-switch on the bottom left of the
Honeywell Standard 16 Connector is not
needed for this thermostat version.
13 Firmly connect remaining wires from
Step 7.
Push down on the tab to put remaining
wires into its corresponding terminal on
the Standard 16 Connector (one wire per
terminal) until it is firmly in place.
Gently tug on wires to verify they are secure.
To release wires, push down the terminal
levers on the on sides of Standard 16
Connector.
