CHOOSING A THERMOSTAT
EMI offers several remote thermostats that are compat-
ible with the Ductless split system air handlers. See the
latest price list for a list of available thermostats. It is impor-
tant to choose a thermostat that will match the equipment
that you have selected. For single stage cooling or heating
choose a single stage Heat/Cool thermostat. If you have
selected an outdoor heat pump unit and an indoor unit with
electric heat then chose a two-stage heating, single-stage
heat pump thermostat.
COOLING ONLY WITH ELECTRIC HEAT OR
HYDRONIC HEAT
Select a thermostat that is compatible with a cooling -
electric heat system. The thermostat should have “R”, “Y”,
“W” and “G” terminals. The thermostat may also have a “C”
terminal.
HEAT PUMP WITH ELECTRIC HEAT
Select a thermostat that is compatible with a cooling,
two-stage heat, heat pump system. The thermostat should
have “R”, “Y”, “O”, “W (or W2)” and “G” terminals. The ther-
mostat may also have a “C” terminal. If the indoor unit is not
equipped with electric or hydronic heat then a single stage
heat pump thermostat is adequate.
FAN OPERATION
Some thermostats are equipped with an
auto/on
fan
switch. When this switch is placed in the
on
position the
indoor fan will run continuous. When the switch is in the
auto
position the indoor fan will cycle with the call for heat-
ing or cooling.
FAN PURGE
The indoor unit is equipped an electronic circuit board
with a purge feature. After the room thermostat has been
satisfied, the purge feature allows the indoor fan to remain
on for an additional 60 seconds. This increases efficiency
by pulling the remaining energy from the unit.

“Other Than EMI”
When selecting a thermostat other than those offered
by EMI, it is important to choose a 24V thermostat that
matches your application. EMI equipment is compatible with
most mercury bulb, digital or power stealing thermostats.
