13. COMMISSIONING
13.1
PRE COMMISSIONING CHECK
Before commencing the commissioning procedure, refer to the design drawing for correct air flows.
See Figure 5.
NOTE:
Extract air and supply air volumes will not always be equal, therefore, when setting up, the extract
system should be the datum.
13.1.1 Ensure that the exhaust and supply grilles or valves are open.
13.1.2 Check the airflow at the grilles or valves, and adjust to suit the design figures.
13.1.3 For bathroom extract this unit is factory set for 8 l/s in trickle mode and 24 l/s in boost mode, based
on the system configuration in Figure 3.
13.1.4 Check the voltage of the RTC PCB battery. Refer to paragraph 14.8.3.
NOTE:
If changes are required to meet differing system specifications the following on site adjustments can
be made.
13.2
FAN ADJUSTMENT FOR EXTRACT
At the start of any fan adjustment, you MUST check the trickle airflow rate and boost airflow rate before
commencing.
13.3
INSTALLER MODE
NOTE:
The install mode has a time out function. If the unit has been powered up but not commissioned
within 3 hours then you will not be able to access the installer mode without first turning the power supply off
for 10 seconds and then back on again.
This function is there to allow for situations where the unit is not taken out of installer mode.
13.3.1 To start installer mode, press installer mode switch.
13.3.2 When installer mode is ready the red LED indicator will start flashing every second. Now extract
and supply fans can be adjusted.
13.3.3 To set trickle see paragraph 13.4.4.
13.3.4 To set boost see paragraph 13.5.4.
13.3.5 Once both setting are correct press installer mode switch.
13.3.6 When out of installer mode the Red LED will stop flashing.
NOTE:
When switch live is OFF there is no switch live present.
When switch live is ON switch live is present.
13.4
TRICKLE AIRFLOW ADJUSTMENT ONLY
13.4.1 Trickle airflow rate needs to be 8 l/s. To adjust this the switch live should be OFF.
NOTE:
During the adjustment do not put switch live ON at any point.
13.4.2 Put unit into installer mode.
13.4.3 To adjust the TRICKLE setting turn RV1 (extract fan) and RV2 (supply air fan) clockwise
to
increase the airflow rate and anti-clockwise
to decrease the airflow rate.
13.4.4 When it is set to 8 l/s, take the unit out of installer mode. Red LED will stop flashing.
13.5
BOOST AIRFLOW ADJUSTMENT ONLY
13.5.1 Boost airflow rate needs to be 24 l/s. To adjust this switch live should be
ON
.
NOTE:
During the adjustment do not switch OFF the switch live at any point.
13.5.2 To adjust the BOOST setting turn RV1 (extract fan).
(In default mode only the extract fan will boost.)
13.5.3 When it is set to 24 l/s, take the unit out of installation mode. Red LED will stop flashing.
13.6
SETTING SPEED POSITIONS
POSITION 1
13.6.1 After setting the required airflows in auto mode turn the switch to position 1.
13.6.2 Ensure unit is out of installer mode and switch live is OFF.
13.6.3 Rotate the potentiometer 1 (on reverse side of the switch) to the
required position to provide the required airflow.
POSITION 2
13.6.4 Turn switch to position 2.
13.6.5 Ensure unit is out of installer mode and switch live is OFF.
13.6.6 Rotate the potentiometer 2 (on the reverse side of the switch) to the
required position to provide the required airflow.
