CAUTION
!
To prevent electrical shock and/or equipment
damage disconnect electric power to system at
main fuse or circuit breaker box until installation
is complete.
Do not use on circuits exceeding specified volt-
age. Higher voltage will damage control and
could cause shock or fire hazard.
Do not short out terminals on gas valve or pri-
mary control to test. Short or incorrect wiring will
damage thermostat and could cause personal
injury and/or property damage.
WARNING
!
This thermostat is intended for use with a 24-volt system;
do not use this thermostat with a millivolt or line voltage
system. If in doubt about whether your wiring is millivolt,
line, or low voltage, have it inspected by a qualified
heating and air conditioning contractor or electrician.
Do not exceed the specification 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 handling or distorting compo-
nents could cause the control to malfunction.
PRECAUTIONS
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
