WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death. Electrical wiring must be done by qualified personnel according to all applicable codes and standards. Before connecting wires, unplug the unit or switch power off at the 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

CAUTION

PROPERTY DAMAGE HAZARD
Failure to comply with the following can cause damage.
If ducts have to go through unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation formation inside and outside ducts, which could cause material damage and/or mould growth. Moreover, if fresh air to the building duct and/or stale air from the building duct goes/goes 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 the main unit Installer Manual for more details.)

INSTALLATION

1. Unplug the ventilation unit.
   NOTE: If the control is to be installed in an electric box, go to step 5.

2. Cut a 27/8″ x 1¾” hole in a wall, at a convenient location for the control. Route a cable (type 22/4) for the control from the unit to this hole.

3. Temporarily place the control over the hole and mark both mounting screw hole positions.

4. Remove the control, drill both screw holes (3/16″ Ø) in the wall and insert the wall anchors (included).

5. 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 colour. Note which wire colour has been chosen for each terminal.

HOW TO USE THE CONTROL

A200535

The main button works following this sequence:

• Click 1 = 30% RH
• Click 2 = 35% RH
• Click 3 = 40% RH
• Click 4 = 45% RH
• Click 5 = 50% RH
• Click 6 = 55% RH
• Click 7 = Dehumidistat disabled and so on

The indicator lights up 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 if the outside temperature exceeds 24°C (75°F).• Press the CONT button to get continuous exchange ventilation at MIN speed. The CONT indicator will light up. 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’s first boot, INT and CONT indicators blink alternately for about 1 minute. If indicators continue blinking after this period, it means that 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).
