FLAME CONTROL UNIT ARREST

CODE GENERATED BY: Failure to ignite burner.

RESET METHOD: Reset occurs automatically when the electrovalve opens again (new attempt at ignition), or after code is

active for 5 minutes.

E 12

FLAME CONTROL UNIT ARREST

CODE GENERATED BY: Flame arrest signal.

RESET METHOD: Reset may be performed via DDC (or S61 board via menu 2, parameter 0). If the code persists, contact

authorised Robur TAC.

E 16

OUTLET WATER TEMPERATURE SENSOR DEFECTIVE

CODE GENERATED BY: Fault (interruption or short circuit) on outlet water temperature sensor.

RESET METHOD: Reset may be performed via DDC (or S61 board via menu 2, parameter 1). If the code persists, contact

authorised Robur TAC.

E 17

COLD INLET WATER TEMPERATURE SENSOR DEFECTIVE

CODE GENERATED BY: Fault (interruption or short circuit) on condenser outlet temperature sensor.

RESET METHOD: Reset may be performed via DDC (or S61 board via menu 2, parameter 1). If the code persists, contact

authorised Robur TAC.

E 18

CONDENSER OUTLET TEMPERATURE SENSOR DEFECTIVE

CODE GENERATED BY: Fault (interruption or short circuit) on condenser inlet temperature sensor.

RESET METHOD: Reset may be performed via DDC (or S61 board via menu 2, parameter 1). If the code persists, contact

authorised Robur TAC.

E 20

CONDENSER INLET TEMPERATURE SENSOR DEFECTIVE

CODE GENERATED BY: Fault (interruption or short circuit) on condenser inlet temperature sensor.

RESET METHOD: Reset may be performed via DDC (or S61 board via menu 2, parameter 1). If the code persists, contact

authorised Robur TAC

E 28

GAS ELECTROVALVE ON IN CASE OF FLAME CONTROL UNIT ARREST

CODE GENERATED BY: Flame control box is in arrest mode (E12) and the gas electrovalve is ON. In this condition the flame

control box is switched in OFF (E12 enabled).

RESET METHOD: The reset can be done via DDC (or S61 electronic board menu 2, parameter 1). If the code error persist

contact Robur personnel.

GAS ELECTROVALVE WITHOUT ELECTRICAL POWER

CODE GENERATED WHEN: Gas electrovalve is off for 5 seconds (with central flame control unit on).

RESET METHOD: Reset occurs automatically if the gas electrovalve switches on again within 10 minutes (with central flame

control unit on).

E 29

GAS ELECTROVALVE WITHOUT ELECTRICAL POWER

CODE GENERATED WHEN: Code

29 is active for more than 10 minutes (with central flame control unit on).

RESET METHOD: Carry out appropriate checks. Reset may be performed via DDC (or S61 board via menu 2, parameter 1).

If the code persists, contact ROBUR TAC.

ANTIFREEZE FUNCTION ACTIVATED – COOLING MODULE

Activation takes place only if the circulator is off and the antifreeze function is enabled (see menu 1, parameter 77).

CODE GENERATED WHEN: Inlet or outlet water temperature of the cold module falls below 4°C (the code generated signals that the

antifreeze function has been activated).

In this case the antifreeze function activates the plant water circulator.

RESET METHOD: Reset (deactivation of antifreeze function) occurs automatically when, with only the circulator on, the inlet

and outlet water temperatures return to over 5°C (in this case the circulator switches off), or if the function

itself is disabled.
