Auto Setback Speed
Setback Speed is a reduced ventilation rate. Auto Setback Speed is automatically
set at the mid point between minimum possible Continuous Speed and the
selected Continuous Speed. The Auto Setback Speed can be enabled by
connection of a volt-free one-way switch, or combined with the Boost Speed with
the 3 position switch TP 508.
Setback Speed
Setback Speed is a reduced ventilation rate. Setback Speed is configured using
a step-less independent fan control potentiometer. The Setback Speed can be
enabled by connection of a volt-free 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
configured using a step-less independent fan control potentiometer.
Boost Speed with Overrun Timer
Boost Speed is an increased speed providing higher extract air flow. Boost Speed
is configured using a step-less independent fan control potentiometer. The Boost
Speed can be triggered by any device which provides a volt-free one-way switch,
such as a PIR, thermostat, humidistat or a standard one-way switch
Boost Overrun Timer
Boost Overrun Timer maintains the Boost Speed for a specific time variable between
0 and 30 minutes. The Boost Overrun Timer time is configured using step-less
independent potentiometer.
Integrated Humidity Sensor
Some units are fitted with an Integrated Humidity Sensor. This continuously
monitors the relative humidity (RH) of the extracted air and triggers Boost Speed
when the relative humidity rises over the set threshold. The Humidity Sensor’s
trigger point is variable from 55%RH to 85%RH and is configured using step-less
independent potentiometer.
