VT9W HE Series Wall Control
Product Information:
The 40355, 40455, and VT9W Wall Controls are compatible with the
ventilation unit. They come with various operating modes to control
the ventilation unit’s functionality. The wall control features an
LCD screen to display the selected mode and error codes. It also
has a backlight that can be activated by pressing any key. The wall
control is powered by a connection to the unit, and it is
recommended to wear safety glasses and gloves during installation.
Disconnecting power is essential to avoid electric shock or damage
to the wall control or electronic module inside the unit.
Wall Control Compatibility:
Refer to the Wall Control Compatibility Chart included with this
wall control for compatibility information.
Wall Control Installation:
To install the wall control:
- Cut a 2 7/8 x 1 3/8 hole in a wall at a convenient location for
the wall control. Note: Dimensions shown are for an installation
without a wall box. - Route the cable from the unit to this hole.
- Strip the end of the cable to access the 4 wires.
- Strip the end of each wire and 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.
Product Usage Instructions:
Operating Modes:
To select an operating mode:
- If the backlight is not illuminated, press any key to activate
the wall control. - Press the MODE key to choose the operation mode of the
ventilation unit (except Turbo mode). - The selected operating mode will appear on the LCD screen.
The available operating modes are:
- STANDBY: Puts the unit on standby mode, where
it will only respond to override wall controls (if present). The
LCD screen will show only the house icon, indicating that the
control is powered on. This is the factory-set default mode. - RECIRC: Recirculates air inside the house on
high speed. - 20 MIN/H: Exchanges air intermittently on a
one-hour cycle. It turns off or recirculates air for 40 minutes
(low or high speed) and then exchanges air for 20 minutes on low
speed. The cycle repeats after every 20 minutes of air
exchange. - CONT: Exchanges air with the outdoors at the
minimum blower speed. - SMART: Manages air exchange based on indoor
humidity measured by the wall control and outdoor temperature. In
Smart mode, the Smart icon appears on the LCD screen along with the
current operating mode called by Smart. - TURBO: Turbo mode is not selected directly but
is activated through Smart mode, Cont mode, 20 Min/h mode, or Eco
mode.
Error Codes:
The wall control may display error codes in case of any issues.
The error codes can be either a 2-digit code or a 3-digit code
displayed on the wall control screen. If an error code is
displayed, perform the following steps to reset the wall
control:
- Press the % HUM, MODE, and TURBO keys simultaneously.
- The wall control will display a 10-second countdown.
- After the countdown, the wall control will be reset, and user
preferences will need to be set again.
Note: Eco mode is exclusively activated by Smart mode. It sets
the unit operation to standby for 50 minutes or in recirc mode for
50 minutes and then exchanges air for 10 minutes on low speed.
The chart below shows the operating modes called by Smart mode,
based on the indoor humidity percentage and the outdoor
temperature.

WALL CONTROL INSTALLATION
! WARNING IT IS 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. TO REDUCE 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. 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.
OPERATING MODES
NOTE: IF THE BACKLIGHT IS NOT ILLUMINATED, PRESS ON ANY KEY TO ACTIVATE THE
WALL CONTROL.
MODE

STANDBY PUT THE UNIT ON STAND-BY MODE, SO IT WILL ONLY RESPOND TO OVERRIDE WALL CONTROLS (IF PRESENT). ON LCD SCREEN, ONLY THE HOUSE IS VISIBLE SHOWING THE CONTROL IS POWERED ON. 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 A ONE HOUR CYCLE AS FOLLOWS: OFF FOR 40 MIN. (OR RECIRCULATION FOR 40 MIN. ON LOW OR HIGH SPEED, SEE BACK PAGE) AND THEN EXCHANGE AIR DURING 20 MIN. ON LOW SPEED. REPEAT CYCLE AFTER THE 20 MIN. OF AIR EXCHANGE.
