Venmar 41402 Guide D'installation Et D'utilisation

The illustrations in this document are generic; your control appearance may be slightly different from the ones shown.
Electrical wiring must be done by qualified personnel in accordance with all applicable codes and standards.
Before connecting wires, unplug the unit or switch power off at service panel and lock service disconnecting
means to prevent power from being switched on accidentally. Always wear safety glasses and gloves while
performing these instructions.
If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation
formation inside and outside ducts, which could cause material damage and/or mold growth. Moreover, if fresh air
to building duct and/or stale air from building duct goes/go through an unconditioned space, the unit must be set
to operate continuously in cold conditions (below 10°C/50°F). Continuous air movement inside ducts will prevent
condensation formation. The unit can be stopped temporarily for maintenance and/or repair purposes in such
conditions. (Refer to section 2.2 from unit User and Installer Manual for more details.)
INSTALLATION

Unplug the ventilation unit.
NOTE: If the control is to be installed in an electric box, go to step

7
Cut a 2 / " x 1¾" hole in a wall, at a
8
convenient location for the control.
Route a cable (type 22/4) for the
control from the unit to this hole. See
figure at right.

Temporarily place the control over the
hole and mark both mounting screw hole
positions.

Remove the control, drill both screw
holes (3/16" Ø) in wall and insert the wall
anchors (included).

Strip the end of the cable to access the 4 wires (about 3"). Strip the
end of each wire (about 1/4"). Connect the wires to the terminals,
regardless of the wire color. Note which wire color has been
chosen for each terminal. See illustration below.

if outside temperature exceeds 24°C (75°F).
• Press the CONT button to get continuous exchange ventilation
in MIN speed (CONT light LED indicator) or MAX speed (CONT
dark LED indicator). To quit this mode, press the CONT button.
• Press the INT button to get intermittent ventilation. The INT
indicator will light up. Within a one hour period, the system will
operate in MIN speed for 20 minutes. To quit this mode, press
the INT button.
• If the maintenance indicator is lit, it means that the filter needs
to be cleaned or replaced. Once the filter is cleaned or replaced,
press the INT button for five seconds to reset the maintenance
indicator. If the maintenance indicator flashes, the LCD screen
on the unit will give the error code. Refer to the Troubleshooting
section in the ventilation unit user guide for more information.
• At unit first boot, INT and CONT indicators blink alternately for
about 1 minute. If indicators continue blinking after this period, it
means that the communication cannot be established with the
ventilation unit. Make sure wires are correctly connected to the
wall control and unit terminals (refer to step 7).

• Click 4 = 45% RH
• Click 5 = 50% RH
• Click 6 = 55% RH
• Click 7 = Dehumidistat disabled
• and so on
The indicator lights up as per the selected
RH. If the set point is exceeded, the system
will operate in MAX speed until the set point
is reached. The dehumidistat will deactivate
