How to adjust the Heat Recovery Ventilator wall sensor
Locate the wall sensor, usually mounted in a central area of the home. It will have a small cover plate.
Remove the sensor cover plate to access the adjustment dial or buttons underneath.
Check the HRV settings and user manual to determine the desired temperature and humidity setpoints for the sensor.
Use a small screwdriver to turn the adjustment dial or press the buttons to change the wall sensor’s internal settings to the desired temperature and humidity setpoints.
Replace the cover plate when finished adjusting settings.
Allow time (hours) for readings to stabilize based on new settings before making further adjustments.
The sensor readings should now match the setpoints programmed.
