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.

The auxiliary contact relay can be used
in two ways.
a) Dry Contacts
The A1 and A2 contacts
are factory set as dry con-
tact points. Connect them
to the damper or economizer
as with any set of dry con-
tact terminals.
b) 24V Contacts
Place a jumper between R
and A2. When the relay is
energized, there will be 24V
at A1. To provide 24V power
to the economizer or damper,
wire the unit to the A1 and C
terminals on the thermostat.
Note: 1 amp max load on relay.
