Operating your HRV

After an HRV has been installed, balanced and functioning, its

ongoing operation is relatively simple. You can help ensure the

safe and reliable performance of your HRV by paying attention to

the manufacturer’s and installer’s instructions and following the

guidelines in this section.

Controls

First, become familiar with the HRV’s controls, which allow you to

adjust the rate of air exchange and, to some degree, the humidity

level in your home. Depending on the installation and HRV model,

operating controls may be located on the HRV itself and/or in the

kitchen, laundry room, bathroom or hallway. Pollutant sensors may

be installed in other rooms. Typically, the main HRV control is

placed adjacent to the home’s main thermostat.

The operating controls include the following functions, depending

on the installation and HRV model.

• Speed controls for the ventilation rate.

• Acirculation mode setting, which circulates air inside the home

but does not exchange indoor and outdoor air.

• Adehumidistat that will trigger the HRV into high-speed

operation when the humidity level in your home reaches a

pre-set level.

• Atimer, which can be set to run the HRV at high speed for

speciﬁed intervals.

• Anintermittent exchange mode setting that automatically turns

on the HRV at low speed for speciﬁed intervals.

• Pollutant sensors that increase the ventilation rate when

pollutant levels in the home rise.

• Amaintenance light, which comes on automatically when

the ﬁlters, and possibly other components, need to be cleaned

or serviced.
