DOL 278AT
13.6.2 Test of Installation
Test only one house at a time.
For a 2-house emergency opening system, start with house 1 in the left-hand side of DOL 278AT.
Carry out the test early in the morning before the outdoor temperature becomes so high that the inlets
are already open or the outdoor temperature compensation (yellow lamp) prevents the inlets from
opening.
1) Connect the panel and main voltage (115, 200 or 230/240V). One of the three battery lamps
must be on.
2) Connect the battery wires: Red wire to red battery connector and black to black.
(If the red battery lamp is on, the battery should charge for at least 10 minutes before the first
test).
3) Turn the button – in the side which is not tested – up to 45°C = not active.
4) Turn the relevant temperature button on DOL 278AT a little.
The climate computer display shows the setting of the button together with the set temperature
of the house (

).
5) Turn the button (counterclockwise) to 10°C = ' TEST '
(measures the battery voltage
after 10 secs.).
6) Check the battery voltage in the climate computer.
(

'Current voltage' (battery) for partially charged battery should be higher than 18 V.
7) Check that the red emergency opening lamp and the green opening lamp switch
on.
8) Check that the system opens in the correct house.
9) Check that all the fans are still running.
•
Check that the green battery lamp is on.
(If the yellow battery lamp is on, the battery is not fully charged. If the red battery lamp is
on, the battery is almost discharged or the 15A battery fuse/battery wire is disconnected).
10) Turn the emergency temperature button slowly upwards (clockwise) just until the red lamp
switches off and continue an additional 1-2°C.
The red lamp and the green opening lamp must still be off.
11) Heat the DOL 278AT temperature sensor of the correct house in your hand for a couple of
minutes. (Note that it is not the indoor temperature sensor of the climate computer).
12) Check that the red lamp switches on in the same side as in item 7.
The green opening lamp switches on for a couple of seconds every three minutes at
the same time as the house opens a little. This can, however, be difficult to see.
13) The red lamp must switch off again when the DOL 278AT temperature sensor has
cooled off.
For a 2-house emergency opening system, repeat the test for house 2 (2 rotary buttons on the
emergency opening).
