40 Condenser difference
max.limit
Too high
temperature over
condenser
Check heating circuit
venting.
Increase pump rotation
speed.
41 Condenser difference
min.limit
Too low temperature
over condenser
Slow down pump rotation
speed.
42 Evaporator difference
max. limit
Too large
temperature
difference over
evaporator
Check ground circuit
venting.
Increase pump rotation
speed.
Check screen.
43 Evaporator difference
min. limit
Too small
temperature
difference over
evaporator
Check compressor
operation.
106 Source temp too low Too low ground
circuit temperature
Vent ground circuit.
Check that pump rotation
speed is at maximum.
107 Hot-gas compressor 1 Compressor hot gas
temperature too high
Check:
● collector circuit
temperature
● condensation
temperature
● expansion valve
setting
222 High-press in HC
operation
E10 Compressor has
reached maximum
pressure at pressure
side
Adjust maximum
temperature for outgoing
water lower.
223 High-press on start
HC
E10 Compressor
has reached
overpressure at HC
circuit start-up
Check that condenser
pump is operational.
Check screen.
224 High-press on start
DHW
E10 Compressor
has reached
overpressure at
DHW heating start-
up
Check that condenser
pump is operational.
