Start-up and inspection
1. The compressor heater (CH) must have been opera-
tional for at least 6 - 8 hours before the compressor
start can be initiated. This is done by switching on
the control voltage and disconnecting the commu-
nication cable.
2. F2040 must be addressed if it is to have another
address than 1. See chapter Addressing via cascade
connection, on page 38.
3. The communication cable on the terminal block
AA23-X4 must not be connected.
4. Turn the isolator switch on.
5. Ensure that the F2040 is connected to the power
source.
6. After 6 – 8 hours, connect the communication cable
(W2) to the terminal block AA23-X4.
7. Restart the indoor module. Follow the instructions
for "Start-up and inspection" in the installation
manual for the indoor module.
The heat pump starts 30 minutes after the outdoor unit
has been powered up and the communication cable
(W2) has been connected, if necessary.
If scheduled
silent operation
is required, it must be
scheduled in the inner section or control module.
Caution
Silent mode should only be scheduled period-
ically because the maximum output is limited
to approx. the nominal values.
Caution
Do not start any electrical work until at least
two minutes after cutting the power.
