WIRING DIAGRAM NOTES
1. Dashed lines are optional.
2. Optional common wire
allows system to power
thermostat.
3. Use “B” or “O” wire - but
not both in heat pump systems.
Generally neither are required
in a conventional system.
4. If “Y” and “C” wires are both
present, then “C” is a common
wire.
5. If a “B” wire in your system
is a common wire then
connecting it to the B terminal
may cause damage to your
system.
WARNING: THIS IS A LOW
VOLTAGE THERMOSTAT (24
volts). A SERIOUS RISK OF
FIRE EXISTS IF YOU CONNECT
THIS THERMOSTAT TO A LINE
VOLTAGE APPLICATION
(typically 115 or 230 volts). IF
UNCERTAIN ABOUT THE
VOLTAGE CONSULT A
PROFESSIONAL ELECTRICIAN.
