Measures

D3 Low pressure

Low pressure fault
■ Heat pump faulty
■ Fan faulty or air ducts

blocked

■ Low pressure sensor

faulty

■ Have heat pump tested

by a refrigeration engi-
neer.

■ Check fan and shut-off

facilities; clean air ducts
if required.

Check low pressure sen-
sor, lead and EEV control-
ler. If required, check
whether jumper in plug

aYH

between terminal 3

and 4 is fitted (switching
signal can be tested at ter-
minal 1X5.7 (230 V) and
must be continuously
active if a pressure sensor
is installed).
