1.3 A) RECOVERY Units with a heat recovery core (Solo units) are designed specifically to control excess humidity and reduce ventilation costs by recovering the heat energy from the exhausted air, and using that same heat energy to warm the fresh air being supplied. This heat recovery process is accomplished in such a way that the stale air is never mixed with the fresh air.
1.4 DEFROST MODE When the outside temperature is below -5°C (23°F), recovery (of heat or energy) creates frost in the module. To maintain its proper operation, the unit is programmed to defrost the recovery module. The defrost frequency varies according to the outside temperature. Defrost lasts 6 minutes for Solo models and 9 minutes for Duo models (or 10 minutes for all models if set on “Extented Defrost”). During the defrost cycle, the unit shifts to maximum speed and the dampers close.

2.2 USING THE ALTITUDE MAIN CONTROL ON-SCREEN INDICATORS 8 10 9 11 12 7 13 6 1 VC0099 5 1 2 3 4 5 6 3 4 SMART Mode. Entirely automatic mode optimizing the ventilation. Temperature Indicators. Program Mode. Allows to program the desired ventilation according to the period of the day. Recirculation Mode. Manual mode performing air recirculation inside the house. Ventilation Mode. Manual mode performing air exchange with the outside.
2.2 USING THE ALTITUDE MAIN CONTROL (CONT’D) The Altitude main control is pre-programmed and ready to go. All you have to do is to set day and time. Then check the settings below and change if needed. SETTING PREFERENCES Press on MODE / PREF key (D) for 3 seconds. NOTE: You can exit Preferences setting by pressing on MODE / PREF key (D) for 3 seconds any time in the process, or wait 60 seconds. The modified values will be kept in memory.
2.2 USING THE ALTITUDE MAIN CONTROL (CONT’D) Pressing on MODE / PREF key (D) successively allows to go from Ventilation mode to Recirculation mode and then to Program mode (VENT 5 , RECIRC 4 and PROG 3 on control screen). • In Ventilation Mode, use to change the ventilation speed (displayed in 13 in all options except RECIRC). • In Recirculation mode, use to change the recirculation speed (displayed in 13 , OFF, MIN, MAX).
USING THE DECO-TOUCH MAIN CONTROL BACKLIGHT IF THE BACKLIGHT IS NOT ILLUMINATED, THE FIRST BUTTON PRESSED (NO MATTER WHICH BUTTON) SHALL TURN ON THE BACKLIGHT. THE BACKLIGHT REMAINS ILLUMINATED FOR 10 SECONDS AFTER THE LAST BUTTON PRESSED. VC0117 OPERATING MODES 2.3 OR TO CHANGE THE OPERATION MODE OF THE VENTILATION UNIT, PRESS THE UP OR DOWN ARROW BUTTON. OPERATING MODE LABEL WILL THEN SCROLL UP OR DOWN ON LCD SCREEN.
USING THE DECO-TOUCH MAIN CONTROL (CONT’D) HOW TO SETTING (RH) LEVEL AND CHOOSE BETWEEN RECIRCULATION IN STAND-BY SET THE RELATIVE HUMIDITY OFF IN STANDBY OR THE RELATIVE HUMIDITY LEVEL ALLOWS TO SELECT THE MAXIMUM DESIRED INDOOR HUMIDITY LEVEL (IN PERCENTAGE). THIS VALUE WILL BE USED TO START THE DEHUMIDISTAT OVERRIDE (AIR EXCHANGE IN HIGH SPEED). PRESS OK FOR 3 SEC. TO ACCESS THE THE BACKLIGHT WILL BE ACTIVATED PROCEDURE. AND HOLD SETTINGS MENU.
2.3 USING THE ALTITUDE MAIN CONTROL (CONT’D) DEHUMIDISTAT OVERRIDE SELECTION IN THE OPERATING MODES MIN, MAX, 20 MIN/H AND RECIRC, THE USER CAN SELECT A DEHUMIDISTAT OVERRIDE SO THAT IF THE RELATIVE HUMIDITY HOUSE EXCEEDS THE RH (RH) IN THE SETTING PREVIOUSLY STORED, THE VENTILATION UNIT WILL EXCHANGE IN HIGH SPEED UNTIL THE TARGET INDOOR RH SETTING IS REACHED.
2.4 USING THE VENTA MAIN CONTROL Location: Located in the busiest area of the house. Purpose: To adjust air supply and select desired indoor humidity level. ADJUSTING THE AIR SUPPLY CONTROL a) b) Select speed MIN. or MAX. using switch A (as shown on diagram). • When MIN. (minimum speed) is selected, if the knob B is set above the click, the unit will exchange in low speed with the outside.
2.5 USING THE OPTIONAL CONTROLS A) TIMERS Location: Located in the bathroom or in other locations where there is temporary excess humidity or pollutants. Purpose: To eliminate excess humidity produced by showers or other periodic activities producing pollutants. 20/40/60-MINUTE PUSH-BUTTON TIMER: High speed activation times are in multiples of 20 minutes. • Within 2 seconds, push one time for 20 minutes, two times for 40 minutes, or three times for 60 minutes activation.
3. MAINTENANCE 0 ! WARNING Dangerous voltage may be present. During maintenance and repairs, the unit must always be turned off, then unplugged. We take great care to minimize sharp edges; however, please proceed with caution when handling all components. When cleaning the unit, it is recommended to wear safety glasses and gloves. NOTE: Unit is shown in normal position but can be installed in either the “normal” or “reverse” (upside down) position. MAINTENANCE PROCEDURE: 3.
3.1 EVERY THREE MONTHS (CONT’D) 5. Clean the condensation tray with a damp cloth. 6. Check the exterior air intake hood: • Make sure there are no leaves, twigs, ice or snow that could be drawn into the vent. • Clean if necessary. VD0035 CAUTION Even a partial blocking of this air vent could cause the unit to malfunction. 7. Reassemble the components: • Filters • Door (The door is secured when you hear a click.) 8. Reconnect the power supply. 3.
3.2 ANNUAL 3.2.2 A MAINTENANCE (FALL) (COND’T) Clean the centrifugal fan wheels Disconnect the fan motor wires. VE0050 B Disconnect the rod activating the square damper. C Remove the two screws securing the fan assembly. D C D Pull the fan assembly out of the unit E Check for any dust accumulation on the blades. B VO0050 CAUTION Do not oil the motor! It is already permanently lubricated. VD0139 F Clean with a small brush if necessary. VD0106 3.2.
4. TROUBLESHOOTING If the unit does not work properly, reset the unit by unplugging it for one minute and then replug it. If it still not working properly, refer to table below. TYPE OF PROBLEM TRY THIS... 1. On Altitude wall control, there is no outside temperature displayed on screen . • At its very start-up or after a power failure, it takes some minutes before the outside temperature appears on screen. Set the wall control on MIN or MAX in VENT Mode.
