W.
QC1
:
J14:
Quick Connect 1. Used as an auxiliary output control option. QC1 will be
electrically connected to QC2 when the relay X is closed. Max rating: 1A@24VAC. See
control conditions at S.
X.
Low voltage pilot duty relay
. Normally open. Closes according to selection made at J7
(S). Default: closes when the ERV is turned on.
Y.
QC2
:
J15:
Quick Connect 2. Used as an auxiliary output control option. QC2 will be
electrically connected to QC1 when the relay (X) is closed. Max rating: 1A@24VAC.
Z.
JMP1
: Remote control input selection. Default wall controller is the North American
remote wall control (NA position). J3 (P) must be in INPUT wall position. When J3 is in
0-10V position JMP1 MUST be in EU position for the 0-10V input to work.
**NOTE: designations AA thru FF are for connection to wall control.
AA.
Vr
terminal. For wiring to mating terminal on NA wall controller.
BB.
BLWR
or CFM terminal. For wiring to mating terminal on NA wall controller.
CC.
COM
terminal. For wiring to mating terminal on NA wall controller.
DD.
On/Off
terminal. Wiring to mating terminal on NA wall controller.
EE.
FLT
terminal. Wiring to mating terminal on NA wall controller.
FF.
Vun
terminal. For wiring to mating terminal on NA wall controller.
GG.
Temperature input B
: AUX Temperature thermistor input.
HH.
J4
: Blower control jumper. Default is ‘0’ position for general full air flow range.
II.
J5:
DEFR OPTS: Defrost Jumper. Default position is ‘0’ The heat wheel slows between
18ºF - 8ºF to prevent frost accumulation then stops when outside temperature is below
8ºF. The ‘1’ position will simply turn OFF the machine below 8ºF. Position ‘1’ is intended
for use with a defrost option installed.
JJ.

: Delta Pressure Control input, negative (-). Not functional without Pressure
Control Transmitter option. RecoupAerator has air flow offset capabilities, see airflow
Offsets in this manual.
KK.
Not connected. Empty socket.
LL.
DP IN
: Delta Pressure Control input, po) side. Not functional without Pressure
Control Transmitter option. RecoupAerator has airflow offset capabilities, see airflow
Offsets in this manual.
MM.
BLWR2
: Exhaust air Blower. This output controls the exhaust air blower motor.
NN.
BLWR1
: Supply air Blower. This output controls the supply air blower motor.
OO.
WHEEL:
Wheel motor. This output controls the operation of the heat recovery wheel
motor.
PP.
PIC1:
Main IC chip. Program code label located here.
QQ.
JP3:
Communication jack for the wall controller connection. Wiring order/association
depicted from AA to FF is from ‘top to bottom’ in this orientation.
