Meanings

Remote PSU
To provide extra low voltage capability for use in bathrooms SELV.
Standard
Pull cord or ceiling switch must be pulled to switch unit on and to allow humidity sensing to operate.
Continuous Power
Pull cord or ceiling switch manually operates the fan, unit will always respond to humidity change.
Continuous Running
Fan will run at low speed continuously and increase to the higher speed on pulling the pull cord.
Cord Control
The unit has two pull cords one each side.
One to open the slide, one to close the slide.
Also switching the unit on & off.
Variable Speed
Variable boost speed – used to reduce fan boost speeds in conjunction with open flued appliances, to avoid fumes being pulled back into property. (integral potentiometer adjustment).
Humidistat
Measures a change in humidity to trigger the fan to run or increase in speed.
Ceiling Switch
Momentary switch (M) – using pull cord to break contacts.
Latching switch (L) using normally open and common contacts.
Fitting, wiring and operation instructions are available, please contact Titon Technical Dept.
