DAMAGE TO THE WALL CONTROL OR ELECTRONIC MODULE INSIDE THE UNIT.
CAUTION
FAILURE TO COMPLY WITH THE FOLLOWING CAN CAUSE ERRATIC OPERATION OF THE UNIT
AND/OR THE WALL CONTROL:
NEVER INSTALL MORE THAN ONE X-TOUCH MAIN WALL CONTROL PER UNIT. MAKE SURE THAT
THE WIRES DO NOT SHORT-CIRCUIT BETWEEN THEMSELVES OR BY TOUCHING ANY OTHER
COMPONENTS ON THE WALL CONTROL. AVOID POOR WIRING CONNECTIONS. TO REDUCE

TO CONTROL CONTACTORS OR NEAR LIGHT DIMMING CIRCUITS, ELECTRICAL MOTORS,
DWELLING/BUILDING POWER OR LIGHTING WIRING, OR POWER DISTRIBUTION PANEL.
-
UNPLUG THE VENTILATION UNIT FROM POWER SOURCE.
-
CUT A 2 7/8” X 1 3/8” HOLE IN A WALL, AT A CONVENIENT LOCATION FOR THE WALL CONTROL. ROUTE THE CABLE FROM THE UNIT TO THIS HOLE.
NOTE: DIMENSIONS SHOWN ARE FOR AN INSTALLATION WITHOUT
WALL BOX. -
TEMPORARILY PLACE THE SWITCH OVER THE HOLE AND MARK BOTH MOUNTING SCREW HOLE POSITIONS.
-
REMOVE THE SWITCH, DRILL BOTH SCREW HOLES (3/16” Ø) IN WALL AND INSERT WALL ANCHORS (INCLUDED).
-
STRIP THE END OF THE CABLE TO ACCESS THE 4 WIRES. STRIP THE END OF EACH WIRE. USING A SMALL BLADE SCREWDRIVER, CONNECT EACH WIRE TO ITS CORRESPONDING TERMINAL, ON THE BACK OF THE WALL CONTROL: YELLOW WIRE TO “Y”, BLACK WIRE TO “B”, RED WIRE TO “R”, AND GREEN WIRE TO “G”.
-
MOUNT THE WALL CONTROL TO THE WALL. PLUG THE VENTILATION UNIT AND TEST THE WALL CONTROL OPERATION.

CYCLE AFTER THE 20 MIN. OF AIR EXCHANGE.
CONT
AIR IS EXCHANGED WITH THE OUTDOORS AT THE MINIMUM BLOWER SPEED.
SMART
AIR EXCHANGE IS MANAGED ACCORDING TO INDOOR HUMIDITY MEASURED BY THE WALL
CONTROL AND OUTDOOR TEMPERATURE. IN SMART MODE, THE SMART ICON APPEARS AS WELL
AS THE CURRENT OPERATING MODE CALLED BY SMART (SEE BELOW). 
NOTE: THE ECO MODE SET THE UNIT OPERATION TO STANDBY FOR 50
MINUTES (OR IN RECIRC MODE FOR 50 MINUTES; SEE SETTINGS SECTION) AND THEN
