Wiring

Electrical installation

All electrical installation must be carried out by an approved
electrician in accordance with Approved Document Part P of
U.K. Building Regulations and to the latest IET standards, or
the appropriate regulations in the country of installation (for
fan installation see the iCON 230V Fan Range Installation
and Operating Guide).

Mechanical installation

To install the module in an iCON fan follow the instructions
below. See page 5 for instructional drawings.

1. Remove the fan front cover (see page 7).

2. Lift the fan electrical terminal away from its mounting pillars
and position on the module connector pins. Tighten the two

screws with a suitable screwdriver. Ensure the leads are

under the module retaining cable clamp.

3. Fit the module at a slight angle into the fan housing, ensur-
ing that the locating slot is fully engaged in to locating
block on the fan.

4. Push the module against housing, ensuring the module clip
holds it in place (clicks at the cable clamp). With iCON 15
& 30 the terminal will reposition back over mounting pillars.

For modules with pull cords: Ensure that the pull c ord is
properly located within the cord slot at the bottom of the fan.

For modules with PIR control: Remo ve the oval logo cap
fitted at the bottom of the front cover of the fan. Replace it

with translucent lens supplied with the PIR module. Note:

The lens must be replaced in order for the PIR module to
function properly. Ensure the orientation of the lens is correct
(i.e. the lens should be flush with the surface).

Connecting mains cable into the module

Connect the cable to the 3-way supply connector block (see
wiring diagrams on page 3) ensuring that the supplied cable
clamp is fitted. Refit the front cover.

Note: When using DTM m odule on ini tial connection the
fan will start immediately and continue running for the dura­tion set on the timer function of the module.

Humidity settings

The humidistat is factory pre-set at approx. 70% RH (relative

humidity). Adjusting the “% RH” towards 40% will result in fan
activation at lower humidity (more sensitive). Adjusting the
“% RH” towards “90%” will result in fan activation at higher
humidity (less sensitive).

Time settings

The overrun timer is factory pre-set at approx. 15 min. Ad­justing the “Timer” towards “MIN” will result in a timer overrun
decrease towards 1/2 minutes (depends on module). Adjust­ing the “Timer” towards “MAX” will result in a timer overrun

increase towards 30/45 minutes (depends on module).

2SHM speed settings

The bathroom/kitchen (low/high) trickle speed depends on
fan model used: 7.2/9.5 l/s (iC15), 19.2/23.4 l/s (iC30) or

21.2/25.6 l/s (iC60). You can set it by a two position slide

switch. Boost (pull cord or humidity sensor activated) will
always be fans’ maximum speed.

Front cover removal

3

To remove front cover assembly, first make sure the fan is
off, isolated from the power supply and the iris shutter is
fully closed.

1. Undo the locking screw at the bottom edge of the cover
using a screwdriver.

2. Rotate the cover a few degrees anticlockwise until it clicks
out from the fittings.

3. Remove the cover by pulling it out.

To refit the cover, reverse the above procedure. The iris
shutter should be in closed position after refit. If not, wait
approximately 1 min after fan switch off allowing the actuator
to retract back in the closed position and then refit the cover
again.
