2.24 - Failures display
The boiler has many selectable options. Please ensure the correct selections are made for the type of
installation you have made. If you have selected the use of a room thermostat, or hot water cylinder, the
boiler will not operate until these devices are connected.
The boiler indicates a boiler fault by flashing all segments of the temperature display.
In case of boiler's temperature failure, all 14 LEDs
in front of symbol "°C" are blinking. The boiler is
off, the water pump still running.
In case of Domestic Hot Water sensor failure (if parameter
= 1), all 14 LEDs in front of symbol
"°C" are blinking. The boiler is automatically restricted to heating.
In case of outside temperature sensor failure (if parameter
= 1 or if used to automatic operation -see
§ 2.20-), all 14 LEDS
in front of "°C" are blinking. The boiler is restricted to heating.
Please call the Dimplex Customer Service department -see Servicing section-
2 FLASHING SEGMENTS in front of bar -indicate the system pressure has fallen below the minimum
operating pressure.
• Check if water has discharged from the pressure relief valve. If so call a Dimplex service agent.
• Check for leakage in the system.
Once the fault has been cleared the boiler will turn on again if the system is filled and pressurised to over
0.5 bar.

The setting menu starts (see § 6.3).
Press during 3 sec. : °C will be on display for counter #1, alternating with °C and bar,
meaning power breaker #1 K1 is totalling more than 0999 x 100 = 99.900 cycles.
Press

Starting this menu will automatically restore the weekly shift of the 6 power stages starting sequence back
