Installation Manual
4.1 Replacing Supply Cord
If the mains supply cord to the PSU is damaged, it must be replaced
by the manufacturer, its service agent or similarly qualified persons in
order to avoid a hazard.
5.0 SMOKE / CARBON MONOXIDE ALARM
AUTOMATIC SHUT DOWN
If the unit is required to switch off in the event of smoke/CO detection,
alarms are available with separate relay bases from companies such as:
Kidde – www.kiddesafetyeurope.co.uk
Aico Ltd – www.aico.co.uk
Note: This is a mandatory requirement for all units installed in a 3
Storey property.

6.0 CONTROLS
6.1 Speed Setting
Due to the increased resistance of the carbon and ePM10 filters only
speeds 3-6 should be used. If the unit is currently set to speed 1 or 2
increase to the minimum required speed of 3.
6.2 Selecting Speed
When power to the unit is switched on the display will show the
temperature control option for 2 minutes. Once the start-up pattern
has completed you may now press the “up” or “down” switch to choose
the flow rate appropriate to the property you are installing the unit in.
6.3 Setting Thermostat Temperature
A temperature sensor is fitted to the outlet of the heater and will
control the heater output to maintain the set point. The set point
ranges between 5˚C (fully anti-clockwise) and 15˚C (fully clockwise)
and can be adjusted via the minimum / maximum commissioning pot
located on the ceiling vent diffuser. If the temperature at the heater
outlet sensor is above the set point, the heater will not activate.
6.4 Setting Temperature Operating Mode
When delivered, the unit is set to temperature operating mode setting
of 3 as a default. To change this setting, switch the power to the unit
on (via the supplied isolator). The display in the ceiling vent will show
the start-up pattern for two minutes and the unit will begin running
at speed 6. In this time you can change the temperature setting by
pressing and holding the “up” switch. The display will show a flashing
value of 3 and will increase every 4 seconds. Once you have reached
the temperature setting you require press and release the “down”
button to store the setting. The fan will now enter into its normal speed
setting mode and a speed can be selected at this point.

IMPORTANT
In the event of conducted RF
interference between 80 to 127 MHz or transient
radiated interference between 80 to 87 MHz, the unit
may go into standby mode or the LED display may go
blank and fan stop temporarily, then go into reset mode
(LED flashing with the number of the speed setting) and
run at high speed. The unit will return to normal after
2 minutes after the RF interference has stopped.
IMPORTANT
For good EMC engineering practice, the power supply output
cable and any sensor cables should not be placed within
50mm of other cables or each other.
