Creating bespoke heat exchanger bypass timed programmes
Each of the programmes can be
edited
to create bespoke programmes as follows:
Press “PROG”.
Use the “+” and “-“ buttons to select the programme number (Factory default is P9).
Press “PROG”. The programme number will stop flashing and the first block on the timeline at the
bottom of the screen will begin to flash.
Select the day to be edited by pressing “DAY” until the correct day is displayed along the top of the
screen (1 – Monday, 2 – Tuesday etc.).
To add a 30 minute temperature controlled bypass block (a black square) to the timeline, ensure
that the word “BYPASS” is displayed on the screen by pressing “BYPASS”.
Press the “+” and “-“ buttons to move along the timeline at the bottom of the screen; a block will
be
added
to each position.
To remove a block, remove the word “BYPASS” from the screen by pressing “BYPASS” and press the
“+” and “-“ buttons to move along the timeline at the bottom of the screen; a block will be
removed
from each position.
Daily ‘timeline patterns’ can be
copied
to another day or multiple days to avoid programming each
day individually.
From the home screen press “COPY” then select the day to copy by pressing “PROG” (the day
number will be displayed) and then the day to copy-to by pressing the “+” and “-“ buttons (the day
number will flash). When the two correct days have been selected, press “COPY” and the timeline
pattern will copy across.
Press “SET” to record.
Filter maintenance
The two filters should be cleaned on a regular basis; the exact frequency will be determined by
individual living conditions.
The word ‘Filter’ will appear on the home screen of the digital user-interface after the set time has
elapsed - when this occurs, clean the filters – see page 4 for resetting details.
To remove the two filters, pull out the two caps from the front of the appliance and gently slide out
the filters in their carrier frames.
Lightly vacuum the filters to remove surface debris and then gently wash through in warm soapy
water. Ensure that the filters are completely dry before refitting. Important: do not dry on a
radiator or use excessive heat as this may distort the carrier frames.
Faults
If the digital display shows ‘Fault’ and either ‘Fan 1’ or ‘Fan 2’, there is a potential fault with one of
the fans. If the digital display shows ‘Fault’ only, the external system inhibit may have been
activated. In either case, in the first instance, contact your building services management team.
