IMPORTANT SAFETY INFORMATION WARNING:
•
Always turn off power at the main power source by unscrewing
fuse or switching circuit breaker to the off position before installing,
removing, cleaning, or servicing thermostat.
•
Read all of the information in this manual before installing or
programming this thermostat.
•
DO NOT CONNECT TO 120 VAC. This is a 24V AC low voltage thermostat. Do not install on voltages higher than 30V AC.
•
All wiring must conform to local and national building and electrical
codes and ordinances.
•
Do not short (jumper) across terminals on the gas valve or at the
system control to test installation. This will damage the thermostat
and void the warranty.
•
Do not connect ground to any terminal in this unit.
Recycling Thermostat
If this thermostat REPLACES a thermostat that contains mercury,
DO NOT discard the old thermostat in the regular trash. Mercury
is harmful to humans and the environment. For this reason, do
not open, break, or crush the mercury cell. If mercury leaks from
a damaged cell, DO NOT touch or handle mercury with bare
hands. Use protective, non-absorbent gloves to place mercury
into a sealable container. Fill the container with sand or another
absorbent material and seal the container completely.
Return the mercury or mercury products, in a sealed container, to
Invensys Climate Controls or a local recycling center for proper
disposal. If you have any questions, call Robertshaw technical
support at 1-800-445-8299.
