Error reports
Error 1
Speed error “Supply air” fan (outside air) Target speed is not reached in
terms of ventilation Check air ducts for obstructions (dirty
grille/filter, incorrectly installed valves,...)
Software error Reset (electricity off/on)
Cable break Connect cable correctly
Motor/impeller defective Replace motor/impeller unit
Error 2
Speed error “Extract air” fan (outgoing air) Like “Error 1” (s ee above) Like “Error 1” (see above)
Error 3 -free- - -
Error 4 SD card error when writing Internal error Reset (electricity off/on)
Error 5 Bus overcurrent Too many subscribers connected to
bus
Error 6 -free- - -
Error 7 BASIS VHZ EH voltage to heat module not available Electronic error Reset (electricity off/on)
Error 8
Ext. module (VHZ) mains voltage to KWL-EM unavailable EM module pre-heater with no
power Connect/switch on power
Error 9 Ext. module (NHZ) mains voltage to KWL-EM unavailable EM module auxiliary heater with no
power Connect/switch on power
Error 10 BASIS Int. temp sensor (T1) -outside air- (missing or cable break) Temperature sensor not sending
signal to circuit board Connect temperature sensor correctly
Error 11 BASIS Int. temp sensor (T2) -supply air- (missing or cable break) Temperature sensor not sending
signal to circuit board Connect temperature sensor correctly
Error 12 BASIS Int. temp sensor (T3) -extract air- (missing or cable break) Temperature sensor not sending
signal to circuit board Connect temperature sensor correctly
Error 13 BASIS Int. temp sensor (T4) -outgoing air- (missing or cable break) Temperature sensor not sending
signal to circuit board Connect temperature sensor correctly
Error 14

Error 17 BASIS Int. temp sensor (T4) -outgoing air- (short-circuit) Short-circuit in sensor cable Connect temperature sensor correctly
Error 18 Ext. module configured as VHZ but not available or malfunction Pre-heater programmed, but
corresponding EM module not
connected Reprogramme pre-heater or configure
KWL-EM as pre-heater
Error 19 Ext. module configured as NHZ but not available or malfunction Auxiliary heater programmed, but
corresponding EM module not
connected Reprogramme auxiliary heater or
configure KWL-EM as pre-heater
Error 20 Ext. module (VHZ) duct sensor (T5) -outside air- (missing or cable break) Temperature sensor not sending
signal to circuit board Connect temperature sensor correctly
Error 21 Ext. module (NHZ) duct sensor (T6) -supply air- (missing or cable break) Temperature sensor not sending
signal to circuit board Connect temperature sensor correctly
Error 22
Ext. module (VHZ) duct sensor (T7) – return WW register- (missing or
cable break)
Temperature sensor not sending
signal to circuit board Connect temperature sensor correctly
Error 23 Ext. module (VHZ) duct sensor (T5) -outside air- (short-circuit) Short-circuit in sensor cable Connect temperature sensor correctly
Error 24 Ext. module (NHZ) duct sensor (T6) -supply air- (short-circuit) Short-circuit in sensor cable Connect temperature sensor correctly
Error 25 Ext. module (VHZ) duct sensor (T7) – return WW register- (short-circuit) Short-circuit in sensor cable Connect temperature sensor correctly
Error 26 Ext. module (VHZ) safety limiter automatically triggered Pre-heater coil has overheated!
Bridge not connected or missing System automatically resets itself after
cooling
Find cause of overheating
(volume flow too low,..)
Error 27 Ext. module (VHZ) safety limiter manually triggered Pre-heater coil has overheated!
Bridge not connected or missing Reset (electricity off/on)
Find cause of overheating
(volume flow too low,..)
Error 28 Ext. module (NHZ) safety limiter automatically triggered Pre-heater coil has overheated!
Bridge not connected or missing Auto. system reset after cooling
Find cause of overheating
(volume flow too low,..)
Error 29
Ext. module (NHZ) safety limiter manually triggered Pre-heater coil has overheated!
Bridge not connected or missing Reset (electricity off/on)
Find cause of overheating
(volume flow too low,..)
Error 30 Ext. module (NHZ) Frost protection measured by WW return (T7)
(switching threshold adjustable e.g. < 7 °C) Return temperature too low Check flow temperature, increase if
necessary, outside temperature too cold
Error 31
Ext. module (NHZ) Frost protection measured by supply air sensor (T6)
(switching threshold adjustable e.g. < 7 °C) Return temperature too low Check flow temperature, increase if
necessary, outside temperature too cold
Error 32
Frost protection external WW reg (fixed < 7 °C only PHI) measured either
by (1.) Ext. module (NHZ) supply air duct sensor (T6)
by (2.) BASIS supply air duct sensor (T2) Return temperature too low Check flow temperature, increase if
necessary, outside temperature too cold
