* Assumes 100F inlet and all air passes through element rack. If duct/plenum is larger than element rack (without
factory deflector kit), the air volume external
(passing around) to the element rack must be added to this CFM requirement.
+ At 240 volt, single phase.
Refer to drawing ES5Ø1 and the symbol definitions.
Thermostat Connections - The following descriptions begin at the 24 volt control points. These
are the left lettered terminals on drawing ES5Ø1 shown as square dots.
C -
Common, must be tied to 24 volt system common.
W1 -
First stage heat, first 5KW section (10KW if "X" jumper is in place).
X -
Second 5KW stage, factory jumpered to the "W1" terminal. Typically the "W1" function
controls the first 10KW. An outdoor stat (ODT) can be electrically installed in place of
the "X" to "W1" jumper to keep 5KW off during warmer outside temperatures.
W2 -
Second stage heat, 5KW for 15KW model or 10KW for 20KW model.
O -
Tie point only for wiring from room stat, no internal
Y2 -
Tie point only for wiring room stat compressor wire, basically no internal connection.
R -
24 volt high side, not required for normal functions, can be used as thermostat wire tie
point. Required if the room stat or air handler does not have internal blower "on"
function.
NOTE: This Electro-Duct blower turn on function cannot operate the air handler blower
relay without 24 volts at "R".
G - Air handler blower relay control voltage.
F - Room stat blower input wire, typically tied to room stat "G" terminal.
