184 Service Procedure
4. Method of Checking the Inverter’s Power
Transistors and Diode Modules
Checking failures in power semiconductors mounted on inverter PCB
Check the power semiconductors mounted on the inverter PCB by the use of a multiple tester.
<Items to be prepared>
Multiple tester: Prepare the analog type of multiple tester.
For the digital type of multiple tester, those with diode check function are
available for the checking.
<Test points>
Turn OFF the power supply. Then, after a lapse of 10 minutes or more, make measurement
of resistance.
<Preparation>
To make measurement, disconnect all connectors and terminals.
Inverter PCB
Electronic circuit
According to the checking aforementioned, it is probed that the malfunction results from the
faulty inverter. The following section describes supposed causes of the faulty inverter.
Faulty compressor (ground leakage)
Faulty fan motor (ground leakage)
Entry of conductive foreign particles
Abnormal voltage (e.g. overvoltage, surge (thunder), or unbalanced voltage)
In order to replace the faulty inverter, be sure to check for the points aforementioned.

- 01 room temperature compensation value if needed it is possible to adjust some thermistor value of the unit by a correction value this can be used as countermeasure for thermistor tolerances or capacity shortage the compensated temperature measured temperature plus compensation value is then used for controlling the system and will be displayed in the temperature read out mode see also 9 automatic temperature compensation on page 91 for compensation values for leaving water temperature 96
- 02 setting not applicable 96
- 03 status defines whether the on off instruction can be used in the schedule timer for space heating refer to the operation manual for details how to program the schedule timer the schedule timer for space heating can be programmed in 2 different ways based on the temperature set point both leaving water temperature and room temperature and based on the on off instruction 96
- By default no level is defined so all buttons and functions are operable the actual permission level is determined by field setting for permission level 2 set field setting 0 00 to 2 for permission level 3 set field setting 0 00 to 3 once the field setting is set the chosen permission level is not yet active enabling the selected permission level is done by simultaneously pressing buttons pi and pj immediately followed by simultaneously pressing buttons s and ba and keeping all 4 buttons pressed for at least 5 seconds note that no indication on the remote controller is given after the procedure the blocked buttons will not be available anymore deactivating the selected permission level is done in the same way 96

- Setback function 98
- T temperature set point 98
- T time 98
- The schedule timer for space heating and space cooling along with the quiet mode will be stopped and will not start again the schedule timer icon will not be displayed anymore 98
- The schedule timer for space heating will stop when active at that moment and will start again at the next scheduled on function the last programmed command overrules the preceding programmed command and will remain active until the next programmed command occurs example imagine the actual time is 17 30 and actions are programmed at 13 00 16 00 and 19 00 the last programmed command 16 00 overruled the previous programmed command 13 00 and will remain active until the next programmed command 19 00 occurs so in order to know the actual setting one should consult the last programmed command it is clear that the last programmed command may date from the day before refer to the operation manual the controller will be switched off operation led will stop working however the schedule timer icon will stay displayed which means that the domestic heating stays enabled 98
- When both setback function and schedule timer are enabled 98
