REMKO GPM
Unit without temperature control
For replacing the gas valve, the
CO2 and if necessary the offset
value must be adjusted.
- Start the burner and after swit-
ching on the fan bring the burner
to “maximum output” by pres-
sing and holding the reset button
on the rear of the unit for 2 to 3
seconds.
Operation at maximum output is
indicated by the green LED on the
front of the unit flashing once.
After about two minutes, connect
a gas analyser and read off the
CO2 value.
Compare this value with the values
in the “Gas settings” table for the
type of gas used.
- If the value is outside the spe-
cified range, it can be corrected
with the CO2 regulating screw
on the Venturi tube:
The gas flow rate and accordingly
the CO2 value decrease when the
screw is tightened.
The CO2 value increases when the
screw is unscrewed.
Subsequently set the burner to
“minimum output” by pressing
and holding the reset button again
for 2 to 3 seconds.
Operation at “minimum output” is
indicated by the green LED rapidly
flashing twice.
- Wait until the minimum out-
put at the burner has stabilised
and check that the CO2 value
is equal to or slightly below the
CO2 value at the maximum flow
rate ( up to -0.3%).
A deviating value can be corrected
with the offset screw.
To make changes to values, un-
screw the metal plug and turn the
regulating screw:
The CO2 value decreases when
the screw is unscrewed.
The CO2 value increases when the
screw is tightened.
After making any adjustments with
the offset regulating screw, the
CO2 value at maximum output
must be rechecked by carrying out
the above described steps.
After carrying out these steps, set
the unit to “normal” mode by
pressing and holding the reset but-
ton again for 2 to 3 seconds.
This mode is indicated by the
green LED showing a steady light.
This also occurs when the mains
supply to the unit is disconnected
and reconnected.
Unit with temperature control
For replacing the gas valve, the
CO2 and if necessary the offset
value must be adjusted.
- Adjust the regulating parameters
of the sensor NTC1 (“REG SAN”
on the temperature control) to
a value that is higher than the
value measured by the sensor
NTC1 (“FLOW VL” on the tem-
perature control).
- Switch on the burner.
The burner will reach maximum
output after about two minutes
after starting.
Connect an exhaust gas analy-
ser and read off the CO2 value.
Compare this value with the “gas
settings” (page 32) for the type of
gas used.
- If the value is outside the spe-
cified range, it can be corrected
with the CO2 regulating screw
on the Venturi tube.
The gas flow rate and accordingly
the CO2 value decrease when the
screw is tightened.
The CO2 value increases when the
screw is unscrewed.
Subsequently set the burner to
minimum output by adjusting the
REG SAN value to a value that is
lower than the measured tempe-
rature.
- Wait until the minimum out-
put at the burner has stabilised
and check that the CO2 value
is equal to or slightly below the
CO2 value at the maximum flow
rate ( up to -0.3%).
A deviating value can be corrected
with the offset screw.
To make changes to values, un-
screw the metal plug and turn the
regulating screw:
The CO2 value decreases when
the screw is unscrewed.
The CO2 value increases when the
screw is tightened.
After making any adjustments with
the offset regulating screw, the
CO2 value at maximum output
must be rechecked by carrying out
the above described steps.
Replacing the gas valve and CO2 and offset regulator
We reserve the right to make changes to dimensions and design in the interest of technological advances.
If the unit is not set to
“normal mode“, the control
board will automatically re-
set the unit after 20 minutes.
