INSTALLATION AND OWNER GUIDE FOR 40355, 40455 AND VT9W WALL CONTROLS
WARNING
ITIS RECOMMENDED TO WEAR SAFETY GLASSES AND GLOVES WHILE PERFORMING
THESE INSTRUCTIONS. ALWAYS DISCONNECT THE UNIT BEFORE MAKING ANY
CONNECTIONS. FAILURE TO DISCONNECT POWER COULD RESULT IN ELECTRIC
SHOCK OR 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. TOREDUCE ELECTRICAL INTERFERENCE (NOISE)
POTENTIAL, DO NOT RUN WALL CONTROL WIRING NEXT TO CONTROL CONTACTORS
OR NEAR LIGHT DIMMING CIRCUITS, ELECTRICAL MOTORS, DWELLING/BUILDING
POWER OR LIGHTING WIRING, OR POWER DISTRIBUTION PANEL.
WALL CONTROL INSTALLATION
WALL CONTROL COMPATIBILITY
REFER TO THE WALL CONTROL COMPATIBILITY CHART INCLUDED WITH THIS WALL CONTROL.
UNPLUG THE VENTILATION UNIT FROM POWER SOURCE.
CUT A2 7/8” X1 3/8” HOLE IN AWALL, AT ACONVENIENT
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 ASMALL 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.

THIS IS THE FACTORY SET DEFAULT MODE.
RECIRC
AIR IS RECIRCULATED INSIDE THE HOUSE ON HIGH SPEED.
20 MIN/H
THE VENTILATION UNIT EXCHANGES AIR INTERMITTENTLY ON AONE
HOUR CYCLE AS FOLLOWS: OFF FOR 40 MIN. (OR RECIRCULATION
FOR 40 MIN. ON LOW OR HIGH SPEED, SEE BACK PA G E ) AND THEN
EXCHANGE AIR DURING 20 MIN. ON LOW SPEED. REPEAT CYCLE
AFTER THE 20 MIN. OF AIR EXCHANGE.
