Adjust the boiler according to the system

The operating parameters of the Remeha Avanta have been
factory set to suit most systems. However it is possible to
adjust some of the parameters to enable the Remeha Avanta
to operate more efficiently to match specific system designs
and site conditions. These parameters are split into two spe-
cific 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.

How to change the parameters at user level can be read on
the "Short reference card" provided and therefore will not be
detailed in this Installation and Service manual.
2.10.8 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 installers.
The following settings can be changed at user and service
level:
