C.T.R. FUNCTION PARAMETER 42
The C.T.R. function acts, when the delivery temperature is set
between 55°C and 65°C, by increasing the delivery T° by 5° C if
after 20 minutes of closing of the TA the T° set on the TA has not yet
been reached, and continues to increase the delivery T° up until the
closing of the TA or until the MAX HEATING SET POINT is reached.
Therefore you should consider leaving the function on. Setting
PARAMETER 42 = 1 ON or cancelling it 42 = 0 OFF.

Display and fault codes
Faults
When there is an operation fault, the display shows a flashing code
and the RESET and icons (simultaneously or otherwise). For a
description of the faults, refer to the table in the following page.
Resetting the faults
Wait about 10 seconds before resetting normal operating conditions,
Then proceed as follows:
1. Display only of the icon
The appearance of the icon indicates that an operation fault has
been diagnosed and the boiler will attempt to resolve it autonomously
(temporary stop).
If the boiler does not resume normal operation, there are two possible
display cases.
Case A
disappears, and the RESET icon appears along with a different
alarm code.
In this case, proceed as described in point 2.
CASE A
temporary
fault
definitive
fault
Case B
the RESET icon will appear along with a different alarm code,
together with the .
In this case, proceed as described in point 3.
CASE B
temporary
fault
definitive
fault
Case C
Together with the , alarm code 91 will appear (see description
below).
The intervention of the Technical Assistance Centre is required.
The boiler is equipped with an auto-diagnostic system which, based
on the total number of hours in certain operating conditions, can
signal the need to clean the primary exchanger (alarm code 91).
Once the cleaning operation has been completed, reset to zero the
total hour meter with special kit supplied as an accessory following
procedure indicated below:
- Switch off the power supply
- Remove the electric casing by means of the screws and fixing
hooks
- Extract the connector J13 (see wiring diagram)
- Power up the boiler and wait for alarm 13 to appear on the display
- Disconnect the power supply and reconnect connector J13
- Refit the electric casing and restore the boiler's function.
NOTE:
the meter resetting procedure should be carried out after
each in-depth cleaning of the primary exchanger or if this latter is
replaced.
2. Display only of the RESET icon
Press the
key to restore operation. If the boiler performs the
firing procedure and resumes normal operation, the stoppage can be
attributed to a chance situation.
Repeated lockouts require the intervention of the Riello
Technical Assistance Centre.
3. Display of the RESET and icons
The intervention of the Riello Technical Assistance Centre is required.
Fault on DHW circuit probe - 60
The fault code is only displayed in standby.
Fault J0 (card/interface connection): check that the electrical
connections are correct. If the fault persists after the control, contact
the Riello Technical Assistance Centre.
Fault J1 (without card/remote control panel connection):
to
restore the operation, press key
again and then key
until the
normal operation is restored.
