152
Error in BMU parameter settings
153 EUROCONDENSE EC PLUS disabled
154 Temperature fault
160 Fan speed error
161 Max. speed exceeded
180
Chimney sweep function active
181 Controller stop mode active
183 EUROCONDENSE EC PLUS in programming mode
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 7 and program basic settings or
check value "b 0" (internal BMU-SW diagnostic code, Table 6) and correct parameter error according to error
specification!
4) Error display only, no switch off

Check connection (not present)
Check room control module RRG
Connect compatible room control module
Check bus
Check addresses of connected control modules
Internal BMU error, process sensor, change BMU
Internal BMU error, process sensor, change BMU
Check EUROCONTROL timer master
Allow unit to cool down and reset. If fault occurs
several times, notify heating engineer
(possible short circuit in gas valve)
Not heat requirement, pump defective, radiator valves closed
Check water pressure and add water if required
e.g. contact F7 or F5 open
Reset, if fault occurs a number of time, notify heating engineer,
insufficient gas (see Page 20), check polarity of line power
connection, ignition electrodes and ionization current
Automatic restart attempt by PARAMOUNT
Fan speed above or below speed threshold
Check setting on EUROCONTROL
Check parameters (Tables 7 and 8), heating engineer
Repeat parameter settings
1)
Press reset button
Parameter incorrectly set (Tables 7 and 8), check parameters
or boiler temperature too high
1)
Fan speed not reached
Max. fan speed exceeded
