Remeha Avanta Plus
2.9.7 Adjust the boiler according to the system
The operating parameters of the Remeha Avanta Plus have
been factory set to suit most systems. However it is possible
to adjust some of the parameters to enable the Remeha Avan-
ta Plus
to operate more efficiently to match specific system
designs and site conditions. These parameters are split into
two specific sections
1. User level – Parameters
p
1
to p
6
; can be changed by
the user to suit CH and DHW comfort conditions
2. Service level – p17 to dF ; must only be changed by
Broag approved Engineer after consultation with the
system designer.
o
How to change the parameters at user level can be read in the
“User manual” provided and therefore will not be detailed in
this Installation and Service manual.
2.9.8 Changing the parameters at service level (with
access code)
To avoid non authorised adjustments, some parameter settings
can only be changed once the special access code
12 has
been entered. This code may only be used by qualified install-
ers. The following settings can be changed at user and service
level:
