The boiler control panel is set for the most common heating
systems. With these settings, practically all heating systems operate
correctly. The user or installer can optimise the parameters according
to own preferences.

For the settings of the C630 Eco boiler: The parameters
and settings described are for each boiler module. Each
parameter changing must therefore be done identical on
each module.

6.1.1. General

The boiler is fitted with an electronic regulation and control unit. The
heart of the control system is a microprocessor, the Comfort

a failure is signalled, the boiler stops or becomes locked.

6.2 Error memory

The boiler control is equipped with an error memory. The last 16 errors
encountered are recorded in this memory.

In addition to the error codes, the following data are also saved:

4 Number of times that the error occured: (MK[xx).
4 Boiler operating mode selected (5t[xx).
4 The flow temperature (t1[xx) and the return temperature

(t2[xx) when the error occured.

To view the error memory, you first have to enter access code
