49: Low priority (night standby position)
During night tariff periods, the system stops and displays this service code if storage tank 1 is hot, independent of the amount
of power used at that time, but only after it has operated for at least 20 minutes. During night tariff periods, the system also
only runs if power consumption is high or no additional heat sources is available.
This is a normal, automatic stop. The system will restart once power and heat conditions require it do so.
52: Fluid alarm
There is fluid in the Power Unit. (Not all systems are equipped with fluid sensors.)
The system stops at once (alarm stop).
This may be due to leaks in the cooling water, engine oil or diesel circuits.
55: Aux.-Alarm
Aux.-Alarm belongs to an additional alarm input, which is normally not connected (factory configuration).
The system stops at once (alarm stop).
56: Initial output too high
The system has recorded that the output is too high when starting calibration.
If this service code is displayed, the system ventilates and calibration restarts. Should this alarm service code occur three times
in an hour, this will cause an alarm stop.
This code may be displayed due to problems with the stepping engine, but it is more likely that the engine is not running stea-
dily, possibly due to an interruption shortly before.
58: Over-regulation
Over-regulation was recorded while calibrating. The output must be distributed over at least 15 steps of the stepping engine.
If this service code is displayed, the system ventilates and calibration restarts. Should this alarm service code occur three times
in an hour, this will cause an alarm stop.
This code may be displayed due to problems with the stepping engine, but it is more likely that the engine is not running stea-
dily, possibly due to an interruption shortly before.
61: Gas pressure low
System has stopped (alarm stop).
System is gas-fired, gas pressure is less than the minimum required, so the safety circuit has stopped the engine and displayed
a fault.
The gas safety circuit checks if enough gas is present. It does not do so if the engine is not running.
62: Flue gas pressure high
System has stopped (alarm stop).
The gas safety circuit has detected high pressure in the flue gas, stopped the engine and displayed a fault. The pressure may
have increased because the chimney is blocked or gas has burned in the exhaust.
63: No vacuum in gas engine
System has stopped (alarm stop).
The gas safety circuit has detected that the gas mixer box is not under vacuum.
As the engine is running, the fault is due to a leak or fault in the hose, since the vacuum required is not being created.
65: Engine water temperature high
System has stopped (alarm stop).
The gas safety circuit has detected that the water at the top of the engine is hot, so it has stopped the engine and displayed
a fault.
There are a number of possible faults here:
Not enough water is flowing through the engine, either because there is a blockage or because the pump is
not working properly
No water in the engine
Engine was not properly bled.
