RC/RH Jumper Wire
This thermostat electrically connects
the RC and RH terminals so a jumper
wire is not required. If the application
provides a separate wire for RC and
RH, clip the RC/RH jumper. This will
isolate both terminals so they can be
independently used.
Battery Location
Premium AA alkaline batteries are
required when C-wire is not available.
When C-wire is available, the batteries
provide a back-up source of power
(this will maintain the clock in the
event of a power outage).
