Communication with Indoor Unit
12.3.2.1 Communication Failures Definition
12.3.2.1.1 ‘Bad Communication’ fault
The system keeps a balance of a good/bad communication packet ratio. When the ratio becomes high the system
enters ‘Bad Communication’ fault. The system recovers from that fault when the ratio becomes small again.
When in ‘Bad Communication’ fault, system continues its normal operation and fault code is shown in diagnostics.
12.3.2.1.2 ‘No Communication’ fault
If no legal transmission or no message received for 30 seconds, system enters ‘No Communication’ fault.
When in ‘No Communication’ fault, the fault code will be shown in diagnostics. In this case, the system will force the
compressor to off.
The system will recover from ‘No Communication’ fault when counter is below 10 and legal massage is received.

the ODU unit will be forced to Idle mode.

LOAD is calculated according to the difference between actual room temperature and user set point temperature
by PI control.
The NLOAD setting is done by the indoor unit controller, based on a PI control
scheme.
The actual NLOAD to be sent to the outdoor unit controller is based on the preliminary LOAD
calculation, the indoor fan speed, and the power shedding function.

12.6.3.1Deicing Starting Conditions
12.6.4.1 Deicing Starting Conditions
Deicing operation will start when either one of the following conditions exist:
Case 1: OCT is 8 degree lower then the ambiant temp and the minimum time from the last deicer is passed.
Case 2: OCT is 12 degree lower then the ambiant temp and 30 minutes from the last deicer wa passed.
Deicing interval time when compressor is first started in heat mode, is 10 minutes if OCT < -2, and is 40 minutes
in other cases.
Deicing interval time is changed (increased/ decreased in 10 minutes steps) as a function of deicing time.
In case one of the thermistors is bad the deicer will initiate in predefined intervals.
Deicer may accure also when the unit switch to stanby and the OCT is 8 degree lower then ambiant

An Outdoor fan motor fault message may occur during very high winds outdoors that may stop the
fan rotation for short periods. If so, need to relocate the outdoor unit to a more protected place from
winds or install measure of air deflection in front of the fan outlets.
1) Check OFAN connections - Repair if needed.
2) Rotate the fan slowly by hand - If the fan does not rotate easily, check whether something
is obstructing the fan preventing it from rotating – remove the obstruction if necessary. If no
obstruction and still not operating - the fan motor bearings have seized - Replace the motor.
3) Disconnect the OFAN connector from the main board, switch ON the power and check the fan
