2.6 Installation of the Smart control panel
A maximum of two Smart control panels can be con-
nected to the ventilation unit, with different mutual ID
numbers. A 20 metre long modular cable is included to
connect the control panel. Run the cable to the desired
place where the panel will be mounted. A Smart control
panel can be mounted up to 40 metres from the unit
(using 2 x 20 metre long modular cables).
The front panel on the Smart control panel is released
using a screwdriver to push the retaining clips through
the holes on either side.
If several control panels are connected in chain, the
middle panel’s bus termination is moved to the “Open”
position. The jumpers do not need to be adjusted if only
one control panel is used.
Bus termination: Open
Bus termination: Terminated
The modular cable connected to any outlet socket on
the panel.
Finally, refit the front panel.
2.7 To connect water pipes in the Econo
model
The pipe connections of the Econo model should be ar-
ranged inside the ventilation unit. On both water pipes
are
∅
15 mm ball valves for shut-off. The supply water
pipe is connected to the pipe with the thermostat.
The Econo model requires a continuous circula-
tion of hot water during the heating season
.
The
Econo model ventilation unit should be equipped
with shut-off damper so that the water-heated air
heater cannot freeze during a power failure.
