6.0 Fan Speed Control
The fan speeds of the unit are controlled by two potentiometers (Speed Pots) on top of the unit;
these are clearly marked “Trickle” and “Boost”.
These two separate speed options allow one speed to be set for normal day to day operation (I.e.
Trickle) and an increased speed to be set (I.e. Boost) that operates only when the Grey switch wire is
triggered by a 240v boost signal such as a Wall Switch or Humidity Stat.
If the Boost is required to be set, it should always be set higher than the Trickle.
Turing these Speed Pots clockwise increases the fan speed.
6.1 Tempering Summer Bypass
The Tempering Summer Bypass, unique to Brookvent, operates on a linear scale between 20
Degrees Celsius (No Summer Bypass) and 27 Degrees Celsius (Full Summer Bypass); gradually
increasing the amount of air directed around the Heat Recovery Core as the temperature of the
extract air from the home rises thus comfortably regulating the indoor air temperature during
warmer months.
This feature is factory set, automatic, and requires no maintenance.
