TOOLS REQUIRED FOR INSTALLATION
Assemble a flat blade screwdriver and other
tools as needed (right).
Test to make certain that your heating and
cooling systems are working properly. If either
does not work, contact your local heating/air condi-
tioning dealer. To avoid compressor damage, do
not operate the cooling system if outdoor tempera-
ture is below 50° F [10° C].
TURN OFF POWER to the system at the heat
pump and at the fuse/circuit breaker panel.
Carefully unpack your new thermostat. Save
instructions, proof of purchase from packag-
ing and original receipt.
