19: Production failed while calibrating
Production failure was recorded while calibrating. However, production has started, otherwise service code 86 would be dis-
played.
When this service code is displayed, the system ventilates and calibration restarts. If there is another alarm service code within
one hour of this alarm, this will cause an alarm stop.
20: Oil pressure alarm
Oil pressure has failed during operation. There was oil pressure in the engine when it started up, otherwise service code 12
would have been displayed.
The system stops at once (alarm stop).
This alarm was probably caused by a fault in the lubricating oil system, but could also be due to a defective oil pressure sensor
or line.
21: Hot alarm
Cooling water circuit temperature is too high.
The system stops at once (alarm stop).
Hot alarms may be due to:
Water return temperature too high
Filter blocked
Fault in circulating pump
Engine cooling circuit leak
Air in/insufficient bleeding of bearing circuit, engine cooling circuit, system and consumption circuit
Mixer valve faulty or set too high
Fault in heat sensor
22: No power consumption
No power consumption signals recorded from building in last 72 hours.
This operating status data is checked at 12.00 every day and displayed if necessary. If there is a heat backup, the system will
not generate power. If not, the system will generate just enough heat to supply the property.
Potential cases: low power consumption (less than 0.4 % of rated quantity of current meter), a faulty current meter or signal
cable.
24: Power output too low
The stepping engine is set to maximum output but the system is not producing enough power to reach the specific minimum
output level required.
If this service code is displayed, the system ventilates and calibration restarts. Should this alarm service code occur three times
within an hour, this will cause an alarm stop.
Potential faults in diesel engines are defective mechanical systems in the stepping engine or intermittent fuel supply, e.g. if a
diesel tank is empty. However, unstable engine operations generally can cause this code to be displayed.
With gas-fired systems, the fault may lie in the ignition or gas mix.
47: Additional heat source
Power consumption is low and the system has been informed that another heat source is available which is more economical
than the XRGI system if power consumption is low. The operating status arose during a high tariff period because service code
48 “Night tariff stop” describes the same operating status, only during a night tariff period.
This is a normal, automatic stop. The system will restart once power and heat conditions require it do so.
48: Night tariff period stop
Power consumption is low and the system has been informed that another heat source is available which is more economical
than the XRGI system if power consumption is low. The operating status arose during a night tariff period because service code
47 “Additional heat source” describes the same operating status, only during a high tariff period.
This is a normal, automatic stop. The system will restart once power and heat conditions require it do so.
