10.1 TROUBLESHOOTING

ATTENTION
If the unit operates incorrectly
• If the unit operates incorrectly due to a thunderstorm or amateur radio
interference, or if it stops or does not respond to the remote controller,
turn off the circuit breaker. Wait for about 3 minutes, and then turn on the
circuit breaker and press the ON/OFF button of the remote controller.

Steaming (The Unit)
The room does not warm up or cool down.
The pump is running while the unit is stopped.

10.2 ALLARM CODE USER INTERFACE

Menù Set indoor, Menù label AL
Code Cause
AMbt KCTR room temperature probe failure
AMbH KCTR room humidity probe failure
OUtA External temperature probe failure
OUtU Outlet water temperature probe failure
"Temp. Water Supply System" signal error (terminals
3-4
3-4)
SAnt Storage domestic hot water temperature probe failure
HP Heat pump error. Error code on PCB display.
rEmC Remote controller connection error
Cooling radiant system condensation risk.
The following causes are possible:
- Closed contact between the "Dew Point Sensor" IN-COM
CONd terminals
- OUtU (Par109) < TLiM (Par229) for more than three
minutes
- InU (Par111) < TLiM (Par229) for more than three minutes
Heating radiant system overheating risk (no DHW).
The following causes are possible:
- InU (Par111) > TSUp (Par236) +2 for more than three
SUrr
minutes
- OUtU (Par109) > TReq (Par230) +2 for more than
three minutes
Section II :: Installation and maintenance
CAUTION:
Before requesting service, perform the following checks:
CAUSES OR CHECK POINTS
This is for protection of the system. After a stop, the unit does not start
operation for approx. 3 minutes.
It is caused by defrosting of the unit in heating operation.
Is the temperature set correctly on the KCTR?
Is there an open window or door?
Is there enough circulating water?
Bleed the air from the water and load
The circulation pump operates automatically at times in order to prevent
scale build-up on the pipe walls or protection antifreeze
