(Single Transformer Systems Only)
The thermostat as shipped may not operate the fan correctly. If 
both the heating and cooling system must operate the fan relay, 
remove the yellow factory-installed jumper wire from the Y terminal 
and connect it to the A terminal. The fan should now cycle when the 
termostat calls for either heat or cool.
Heat Pump Applications
This thermostat WILL NOT provide multi-stage heating or cooling 
operation. For single-stage heat pump applications, install a short 
jumper wire across terminals W and Y. If the old thermostat has a 
terminal that is continuously energized, disconnect the wire from the 
old thermostat’s terminal and connect it either to the: ) B terminal, 
if the reversing valve is energized on a call for heat: or to the 2) O 
terminal, if the reversing valve is energized on a call for cool. If the 
system heats on a call for cool, or vice versa, this wire has been 
connected to the wrong terminal.
Special Application Terminals
The B and O terminals can provide switching for special functions 
other than heat pump operation. When the system switch is in the 
HEAT position, the B terminal is energized. When the system switch 
is in the COOL position, the O terminal is energized.
