78: Startup, all tanks cold
When the control system starts the engine, the LCD display shows the start time (also appears in Service Database later).
This code (78) means that all the storage tanks were cold when the engine started (no heat in storage). If there is heat in storage
when the engine starts, code 79 “Start under other circumstances” is displayed.
79: Start under other circumstances
When the control system starts the engine, the display shows the start time (also appears in Service Database later).
This code (79) means the storage tank was partly full when the engine started. If the storage tanks are cold when the engine
is started, code 78 “Start, all tanks are cold” is displayed.
80: System restart
The control system has restarted. This normally means that power was cut, either because there was a power outage or be-
cause the operator has switched the IQ-Control Panel off and on again.
If the system restarts without power being interrupted, this is an isolated case and not important. If this occurs frequently,
however, it means there is a fault in the electronics or power supply.
81: Alarm acknowledged
The operator has acknowledged an alarm. This is merely intended to show that the operator has noticed the alarm and con-
firmed it.
82: Forced startup
The operator has forced the system to start, i.e. the system was in standby mode due to the power/heat situation, but the
operator started it.
83: Network fault
The system has switched to standby mode due to a fault signal from the grid monitoring relay. Once the network is stable
again, the system waits for three minutes, then restarts automatically (assuming the power/heat situation requires it to do so).
If this fault appears, it means there is a:
Phase fault or break
Overvoltage or undervoltage
Overfrequency or underfrequency
86: No power output while calibrating
Code 86 is displayed when the system was not able to generate power while calibrating.
If this service code is displayed, the system ventilates and restarts calibrating. If there is another alarm service code within an
hour of this alarm, this will cause an alarm stop.
It is very probable that one of the diesel units is out of fuel. If the system is gas-fired, the fault may lie in the ignition.
87: Start to sell power
The system is starting up to feed power into the grid.
This can be done within the specified selling period if the storage tanks have been cold for some time.
88: Out of regulation limits
The system cannot regulate downwards any further, i.e. it is running in its minimum range – which is not normal. This is proba-
bly the case because the stepping engine is currently in a higher position than the control system has recorded.
The system tries to resolve the problem by reducing the function of the stepping engine and by starting to recalibrate. If this
error code occurs three times within an hour, this will cause an alarm stop.
89: Forced standby
The system is on standby because the forced standby input was activated. As long as this input is on, the system will remain
on standby, whatever the heat or power situation may be. Check the Service Database, under 'Calls' to see if the input is on
and to see if this is what is causing long outages.
90: Gas alarm when starting engine
The control system has tried to start the engine either because too much power was being consumed or because the storage
tanks were cold. However, it recorded a gas alarm and thus did not start.
The gas alarm occurred either while the system was switched on or when it was switched out.
