- refrain from proceeding by trials and errors. Instead, ask an authorised Robur
Technical Assistance Centre (TAC) to intervene, communicating the operating code
reported;
- disconnect the appliance from the gas and electricity mains, interrupting the gas
supply by means of the tap and the power supply by means of the external
disconnecting switch "GS", and await the arrival of the TAC contacted.
For the operating codes generated by the S61 electronic board of the appliance, refer to
the Table 27 on page 96, that follows.
For instructions regarding how to clear operating codes via the S61 board of the
appliance, refer to paragraph 2.4 on page 21.
TABLE OF OPERATING CODES (firmware release 3.027)
The following operating codes can be generated by the electronic control board S61; they
could be shown both on the same S61 and on the DDC, if present.
U
601
MANUAL RESET OF THERMOSTAT, GENERATOR LIMIT TEMPERATURE
CODE GENERATED BY : High temperature detected by limit thermostat on body of generator (T> 330.8 °F).
RESET METHOD : Reset limit thermostat manually: GAHP-AR operation will be restored automatically when the cause
ceases. If code
U
601 persists, it becomes E 601.
E 601
MANUAL RESET OF THERMOSTAT, GENERATOR LIMIT TEMPERATURE
CODE GENERATED BY :
U
601code active for 1 hour, or
U
601 code generated 3 times in 2 hours of operation.
RESET METHOD
: Contact Robur TAC.
U
602
EXHAUST GAS THERMOSTAT - AUTOMATIC RESET
CODE GENERATED BY
: High temperature detected by exhaust gas thermostat (T> 473 °F).
RESET METHOD : Reset occurs automatically when the condition that generated the code ceases, with hysteresis of
14.4 °F (T< 458.6 °F).
E 602
EXHAUST GAS THERMOSTAT – MANUAL RESET
CODE GENERATED BY :
U
602 code active for 1 hour, or
U
602 code generated 3 times in 2 hours of operation.
RESET METHOD : Reset may be performed through the board via menu 2, Parameter 1 (or from DDC). If code
U
602
and/or E 602 occur again, contact Robur TAC.
U
603
COLD WATER ANTIFREEZE THERMOSTAT
CODE GENERATED BY : Low temperature detected by cold outlet water sensor, or sharp drop in temperatures detected by cold
outlet or inlet water sensor.
RESET METHOD : Reset occurs automatically when the condition that generated the code ceases, with hysteresis of 3.6 °F.
U
604
INADEQUATE VENTILATION / CONDENSER OVERHEATING
CODE GENERATED BY : (TCN - TA) values > limit set.
RESET METHOD
: Reset occurs automatically 20 minutes after the code is generated.
