Setback Speed
Setback Speed is normally a reduced ventilation rate. Setback Speed is congured
using a stepless independent fan control potentiometer. The Setback Speed can be
enabled by connection of a latching mains one-way switch, or combined with the
Boost Speed with the 3 position switch TP 508.
Continuous Speed
Continuous Speed is the normal running speed of the unit. Continuous Speed is
congured using a stepless independent fan control potentiometer.
Boost Speed with Overrun Timer
Boost Speed is an increased speed providing higher extract air ow. Boost Speed
is congured using a stepless independent fan control potentiometer. The Boost
Speed can be enabled by connection of a mains one-way switch, or combined with
the Setback Speed with the 3 position switch TP508.
Boost Overrun Timer
Boost Overrun Timer maintains the Boost Speed for a specic time variable between
0 and 30 minutes after Boost Speed is disengaged. The Boost Overrun Timer time is
congured using stepless independent potentiometer.
Integrated Humidity Sensor
The units are tted with an Integrated Humidity Sensor. This continuously
monitors the relative humidity (RH) of the extracted air. The fan speed increases
proportionally between Continuous Speed & Boost Speed depending on the
measured %RH; see below for details.
The Humidity Sensor’s set point is variable from 55%RH to 85%RH and is congured
using a potentiometer.
