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.
This thermostat is intended for use with a low voltage system; 
do not use this thermostat with a 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 contrac-
tor 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 components could cause 
the control to malfunction.
FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY 
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE 
PERSONAL INJURY AND/OR PROPERTY DAMAGE.

WARNING
!
Do not use on circuits exceeding specified voltage. 
Higher voltage will damage control and could cause 
shock or fire hazard.
Do not short out terminals on gas valve or primary 
control to test. Short or incorrect wiring will damage 
thermostat and could cause personal injury and/or 
property damage.
Thermostat installation and all components of the 
system shall conform to Class II (current limited) 
circuits per the NEC code. Failure to do so could cause 
a fire hazard.
