NOTE: If you install more than one thermostat and
EIM, the EIMs must be at least 2 feet apart.
If installing a discharge/return air sensor, it must
be located between the IAQ equipment and the
heating/cooling equipment. The sensors must be
in air that is mixed well (away from a-coil/heat
exchanger). See page 7.
When used with the EIM, the relays in the thermostat do not function.
