Installation, General - Nibe PKM 20 Montageanweisung

The following must be done so that the heat pump can
start the passive cooling.
1. Shut down the heat pump and make sure it is not
voltage fed.
2. Change to the new supplied CPU-card, minimum
version 1.0.
3. The existing flow sensor (89) should be replaced
with the one fitted to PKM 10/20. Cut off the existing
cables as close to the edge board connector as
possible on terminal X4 positions 15 - 16 on the
EBV-card (2). Ensure that the cut cables do not
touch each other or any metal. Connect the cables
from the flow sensor in PKM directly to the screw
terminals in the same positions. Enclosed is a 3 m
extension cable for the connection between the
sensor and heat pump.
4. If room sensor (RG 10) is used, this is connected to
the EBV-card (2) on terminal X1 positions 3, 4 and
14.
