Errors, malfunctions and messages
7.2
Emergency operation
In the event of incorrect electronic controller settings or 3-way
switch valve malfunctions, emergency heating operation can be
maintained by activating the
"Manual Operation" special
function
on the controller (see chap. 3.5.1 and the
supple-
mentary notes in the installation and maintenance instruc-
tions
of the ROTEX HPSU monobloc compact).
7.3
EHS emergency operation
If the heat pump fails, the backup heater can be used as emer-
gency heating, and can undertake all heating requirements either
automatically or non-automatically (see chap. 3.4.13).
7.4
Malfunctions and fault codes
See ROTEX HPSU monobloc compact installation and mainte-
nance instructions; chapter entitled "Faults, malfunctions, mes-
sages".
To ensure that the error is not caused by incorrect set-
tings, reset all parameters to the factory settings before
any possible replacement of components (see
chap. 3.6.12).
If you are unable to determine the cause of the fault yourself,
please consult a ROTEX service technician.
To do this, please have the important device data available (see
fig. 7-4 for the procedure):

bloc compact (see heat pump type plate).
