WIRING
Refer to equipment manufacturer’s instructions for specic system wiring information. After wiring, see
INSTALLER MENU for proper thermostat conguration. Wiring table shown are for typical systems and
describe the thermostat terminal functions. Wiring will change when dedicated emergency heat is on
(See Installer menu # 15).
THERMOSTAT INSTALLATION
Precautions
• Do not exceed the specication ratings.
• All wiring must conform to local and national electrical codes and ordinances.
• This control is a precision instrument, and should be handled carefully. Rough handing or
distorting components could cause the control to malfunction.
WARNING
!
Do not use on circuits exceeding specied voltage.
Higher voltage will damage control and could
cause shock or re hazard.
Do not short out terminals on gas valve or primary
control to test. Short or incorrect wiring will burn
out thermostat and could cause personal injury
and/or property damage.
CAUTION
!
To prevent electrical shock and/or equipment
damage, disconnect electrical power to system,
at main fuse or circuit breaker box,until
installation is complete.
Leveling Thermostat
Leveling is for appearance only and
will not aect thermostat operation.
CAUTION
!
To prevent compressor and/or property damage, if the outdoor temperature is below 50°F,
DO NOT operate the cooling system.
Do not allow the compressor to run unless the compressor oil heaters have been operational
for hours and the system has not been operational for at least minutes.6 5 2

RC/RH Jumper Wire
This thermostat electrically connects
the RC and RH terminals so a jumper
wire is not required. If the application
provides a separate wire for RC and
RH, clip the RC/RH jumper. This will
isolate both terminals so they can be
independently used.
Baery Locaon
Premium AA alkaline batteries are
required when C-wire is not available.
When C-wire is available, the batteries
provide a back-up source of power
(this will maintain the clock in the
event of a power outage).
