We live in a newly-renovated apartment Montréal on the second floor. 1. When we are absent for a few days to a few weeks, should we turn off the air exchanger? 2. If we open windows, should we turn off the air exchanger? 3. With a desire to cut outdoor noise and still have fresh and cool air, is it a good idea to put the air exchanger on MAX at night and keep the windows closed? 4. Should we always have the windows closed at all times if we have an air exchanger and heat pump (thermopompe)?

The Venmar K7 ERV should operate continuously if the ductwork passes through an unconditioned space, except during maintenance or repair. It should not be used during construction, renovation, or when sanding drywall. Windows do not always need to remain closed when using the unit, but for optimal performance and to minimize outdoor noise, it may be beneficial to keep them closed, especially at night if set to MAX. There is no specific instruction to turn the unit off when away for a few days or weeks, so continuous operation is likely preferred unless maintenance or repair is needed.
