2.10.7 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 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 - [P][1][7] to [d][F] ; must only be changed by Remeha 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
[1][2] has been entered. This code may only be used
by qualified installers.
The following settings can be changed at user and service level:
