Installation
NOTE: If your thermostat has one wire marked R or RH (4-wire system), then leave the
jumper wire between the RH and RC terminals. Otherwise, if you have separate RH and RC
wires (5-wire system), then remove the jumper wire between the RH and RC terminals.
NOTE: Do not connect a “Common” wire (sometimes labelled “C”) to any terminal on this
thermostat. Tape up the wire and do not use.
