(E80) (E82) Draught control enabled but draught servo disabled.
Draught servomotor must be enabled for draught control.
Check expansion options 80 and 82.
(E120) (57) Heat flow requires fuel flow to be optioned and commissioned.
If heat flow function is set, fuel flow metering must be optioned and commissioned.
Check expansion 120 and option 57.
(E120) (1) Steam flow requires a boiler pressure sensor.
A boiler load/external pressure detector must be set for steam flow metering.
Check expansion option 120 and option 1.
(E120) (1) Water flow requires a boiler temperature sensor.
A boiler load/external temperature detector must be set for hot water flow metering.
Check expansion option 120 and 1.
(E127) (E128) Steam flow start pressure offset must be less than stop offset.
The steam flow start pressure offset cannot be set higher than the steam flow stop pressure offset.
Check expansion options 127 and 128.
(E140) (12) Fully metered cannot be optioned with EGA trim.
Fully metered control can be used with the EGA set as monitoring only, but not 3-parameter trim.
Check expansion option 140 and option 12.
(E140) (E4) Fully metered cannot be optioned with external water level probe.
Fully metered control cannot be used with external water level probe (terminals EX- and EX+ are
required for both features).
Check expansion options 140 and 4.
(E140) (E120, E129) Fully metered cannot be optioned with local heat flow.
Fully metered control cannot be used with steam or hot water flow metering.
Check expansion options 140, 120 and 129.
(E140) (E141, E143) Fuel temperature cannot be optioned with mass flow meter.
Fuel temperature sensor cannot be used with a fuel mass flow meter in fully metered control.
Check expansion options 140, 141 and 143.
(E140) (E141, E145) Fuel pressure cannot be optioned with mass flow meter.
Fuel pressure sensor cannot be used with a fuel mass flow meter in fully metered control.
Check expansion options 140, 141 and 145.
(E140) (E142, E144) Air temperature cannot be optioned with mass flow meter.
Air temperature sensor cannot be used with an air mass flow meter in fully metered control.
Check expansion options 140, 142 and 144.
(E140) (E142, E146) Air pressure cannot be optioned with mass flow meter.
Air pressure sensor cannot be used with an air mass flow meter in fully metered control.
Check expansion options 140, 142 and 146.
(E140) (150, E154) Fully metered requires gas fuel 1 to have non-zero density.
Density must be set for gas in fully metered control.
Check option 150 and expansion options 140 and 154.
(E140) (151, E155) Fully metered requires gas fuel 2 to have non-zero density.
Density must be set for gas in fully metered control.
Check option 151 and expansion options 140 and 155.
(E140) (152, E156) Fully metered requires gas fuel 3 to have non-zero density.
Density must be set for gas in fully metered control.
Check option 152 and expansion options 150 and 156.
