Step 9: Disconnect and label old thermostat wires
Disconnect and label the wires from your old thermostat carefully, one wire at a time, using the wire
labels provided. If you have connected the C-Wire Adapter, label the wire connected to the G terminal
with the GK wire label and label the wire connected to the Y/Y1 terminal with the YK wire label.
Make sure the wires do not fall back into the wall when released from the terminals and that the labels
are fastened to the wires securely.

Jumper wire
Note: If the terminals on your old thermostat has a jumper wire between RH, RC or R, remove
the jumper wire. Your new TrickleStar Thermostat does not need this jumper wire.
