Calibration of the firing unit
1. Switching the ROTEX GCU compact off and on again.
2. Place the rotary switch in the
"Configuration"
position.
Î
An overview is displayed.
3. Select the
"SCOT config"
level with the rotary switch.
Î
An overview is displayed.
4. Using the rotary switch, select the parameter [100%
Calibration] and confirm.
Î
An overview is displayed.
5. Using the rotary switch, select the parameter [Drop Io-base]
and confirm.
Î
Calibration running. After calibration is complete, an
adjustment range of -5 to +10 is displayed.
6. Connect the flue gas analysis unit to the GCU compact.
7. Using the rotary switch, adjust the parameter [Drop Io-base]
so that the flue gas values lie in the target value range.
8. Confirm the changes with a brief push of the rotary switch.
Î
Calibration is complete.
Î
Burner starts without problems: No further measures are
required.
Î
Burner start has faults: Check and, where necessary,
adjust the starting output of the burner.
Checking, adjusting the starting output of the burner
The setting of the parameter [Corr power start] is directly asso-
ciated with the structural design.

"SCOT config"
level with the rotary switch.
Î
An overview is displayed.
3. Using the rotary switch, select the parameter [Corr power
start] and confirm.
Î
Current value is displayed.
4. Using the rotary switch, adjust the parameter [Corr power
start].
5. Confirm the changes with a brief push of the rotary switch.
6. Switching the ROTEX GCU compact off and on again.
7. Generate a burner demand (e.g. heating operation).
Î
Burner starts without problems: No further measures are
required. Enter the performance changes in the opera-
tional handbook and confirm with your signature.
Î
Burner start has faults: Re-adjust the starting output and,
adjust the gas volume where necessary.
Adjusting the gas volume at the burner start
The gas volume at burner start can be set up by adjusting the pa-
rameter [Corr qGas start].
1. Place the rotary switch in the
"Configuration"
position.

2. Select the
"SCOT config"
level with the rotary switch.
Î

3. Using the rotary switch, select the parameter [Corr qGas
start] and confirm.
Î
Current value is displayed.
4. Using the rotary switch, adjust the parameter [Corr qGas

Î
Burner start has faults: chapter 10 "Faults and malfunc-
tions".
With
starting problems after
a
replacement
of the safety
gas
control block
:
By setting the parameter [CL - Offset CES] the starting configu-
ration of the safety gas control block can be adjusted for the first
burner start.
1. Place the rotary switch in the
"Configuration"
position.

2. Select the
"SCOT config"
level with the rotary switch.
Î
An overview is displayed.
3. Using the rotary switch, select the parameter [CL - Offset
CES] and confirm.
Î
Current value is displayed.
4. Using the rotary switch, adjust the parameter [CL - Offset
CES].
5. Confirm the changes with a brief push of the rotary switch.
6. Switching the ROTEX GCU compact off and on again.
7. Generate a burner demand (e.g. heating operation).
Î
Burner starts without problems: No further measures are
required.
Î
Burner start still has faults after several corrections: see
chapter 10 "Faults and malfunctions".
In case of
noise problems
(whistling, humming, or the like), ad-
justing the starting parameters described previously (starting
output, gas volume burner start) can provide a remedy.
When operating with natural gas, removing the air inlet collecting
pipe (fig. 7-2, item 12) may also be successful.
Disruptive noise caused by resonance can be reduced effectively
using a silencer (see chapter 4.2).
CAUTION!
The firing unit is programmed to take into account the
ageing of the components. Calibrating the firing unit
can still have a negative impact on this even when
complying with the exhaust setting values (tab. 5-1 to
tab. 5-3).
Ɣ
Only carry out a calibration of the firing unit when
the exhaust setting values are not adhered to, or
when a mechanical change was carried out, e.g.
by replacing the component with original ROTEX
spare parts.
