INSTALLATION
REMOVE OLD THERMOSTAT
1. Shutoffelectricityatthemainfuseboxuntilinstallationis
complete.Ensurethatelectricalpowerisdisconnected.
2. Removethefrontcoveroftheoldthermostat.With wires
still attached, removewallplatefromthewall.Iftheold
thermostathasawallmountingplate,removethethermostat
andthewallmountingplateasanassembly.
3. Identify each wire attached to the old thermostat using
the labels enclosed with the new thermostat.
4. Disconnectthewiresfromoldthermostatoneatatime.DO
NOT LET WIRES FALL BACK INTO THE WALL.
5. Installnewthermostatusingthefollowingprocedures.
