61
Fault, room control module RRG
Check room control module RRG
62
Wrong room control module connected
Connect compatible room control module
81
Short circuit on LPB bus or no bus feed
Check bus
82
Address conflict on LPB bus (EUROCONTROL)
Check addresses of c onnected control modules
91
EEPROM data loss
Internal BMU error, process sensor, change BMU
92
Hardware error
internal BMU error, process sensor, change BMU
100
Two time master
Check EUROCONTROL time master
110
Limit stat tripped
Allow unit to cool dow n and reset. If fault occurs several
times, notify heating engineer 1) temperature stat open
circuit (possible short circuit in gas valve) 3)
111
Max. temperature tripped
No heat requirement, pump defective, radiator valves closed
119
Water pressure switch tripped
Check water pressure and add water if required 2)
132
Safety switch off
e,g, contact F7 open (Pressure Switch)
Possible low gas pressure
133
No flame detected (no flame message after expiration of
safety time)
Reset, if fault occurs a number of time, notify heating
engineer, insufficient gas 9see Page 20) check polarity of
line power connection, ignition electrodes and ionisation
current 1) 2)
134
Flame failure during operation
Automatic restart attempt by PARAMOUNT
135
Incorrect air supply
Fan speed above or below speed threshold 2)
140
Impermissible LPB segment number or equipment number
Check setting on EUROCONTROL
148
Incompatibility between LPB interface basic unit
Check setting on EUROCONTROL
151
Internal error in BMU
Check parameters (Tables 5 and 6) heating engineer 1) 2)
152
Error in BMU parameter settings
Repeat parameter settings
153
PARAMOUNT disabled
Press reset button 1)
154
Temperature fault
1.
Boiler temperature rises too fast.
2.
Return temperature higher than flow temperature
3.
Return temperature more than 50°C below flow temp,
check water flow through boiler.
4.
Parameter incorrectly set (tables 5 & 6) check
parameters 1) 3)
160
Fan speed error
Fan speed not reached 1)
161
Max. speed exceeded
Max. fan speed exceeded
180
Chimney sweep function active
4)
181
Controller stop mode active
4)
183
PARAMOUNT in parameter setting mode
1)
bu
Faulty connection between Control unit and LMU
Check wiring in-between and replace control unit if
necessary
Display of 3-digit error messages: The 1 in the number 100 is displayed alternately with the 10’s position
1)
Switch off and disable; can be enabled only with reset
2)
Switch off, start prevention; starts backup after fault disappears
3)
Check parameters according to Table 8 and program basic settings or
check value “b 0” (internal BMU-SW diagnostic code, Table 5) and correct parameter error according to error specification!
4)
Error display only, no switch off.
