2.2.1.2. Maintenance

T here are 45 alarm codes for identifying and easily locating any fault or problem in the unit. The alarms are classified into groups to facilitate maintenance procedures.
Auto-diagnostic: Quick diagnostics function for controller cards, cards in connected indoor units and cards in outdoor units (PCBs) using the LCD screen. Remote control data storage: The remote control stores all information on the status of the units at the time when the last system alarm was triggered, allowing the user to easily ascertain the cause of the alarm and resolve the problem. The remote control memory stores all of the pre-configured information of both the remote control and the connected units. Optional function settings: arious optional functions on the indoor units (IU) can be activated or deactivated using the remote control, for example: V - Calibration phase shift of 4 SDgrC in heating mode (see Tab. 6, point ). - Fan speed - Thermostat, etc. everal indoor units (IU) can be adjusted at the same time or their configuration can be changed after installation.

This function allows the user to control the outdoor air intake based on the humidity sensor connected. This function is used to ensure that the air pressure in the room is greater than the pressure in the adjoining rooms. This function is used to force the recycling of air in the room when the gas sensor (CO2) is activated. This function delays the start-up of the total heat exchanger. This function is used to automatically set the OFF timer when the unit is started up by the remote control.

. Resetting heating temperature calibration. This function is used when the remote control setting or set-point temperature and the indoor unit suction air temperature need to be the same. In standard heating mode, the suction air temperature is greater than that of the room, therefore the setting temperature used is calibrated to the indicated temperature +4 C. Setting Temperature Used = Indicated Setting Temperature + 4 C (b1=0) / +0 C (b1=1)This function is useful when the thermistor is removed from the indoor unit suction area and is installed in a different location. The following table shows the indicated setting temperature and the suction air temperature after resetting the heating temperature calibration. . Maintaining ventilation speed in the event of a thermostat stoppage in heating mode. If the fan speed changes to "LOW" when the thermostat of the unit is stopped, the air in the room may become stratified due to hot air accumulating on the ceiling. In this case, we recommend the use of the circulation pump function explained below. This function maintains the ventilation speed when a unit running in heating mode has a thermostatic fault. This keeps the movement of the air in the room at the same level as when the thermostat is running, ensuring a uniform air distribution. If the indoor unit is fitted with an automatic swing louver, this will also be kept running when the heating thermostat is deactivated. . 3 minute minimum forced compressor operation. When a compressor is frequently started and stopped over short intervals, it must be protected by using this function. Activating this function adds the minimum three-minute operation mode (a stop mode of a minimum three minutes is standard). If using SET-FREE, this function is configured by default.

Description The 8 pin DIP switch (S201) setting is determined by the numbers of the outdoor units (OU) and the numbers of the corresponding indoor units (IU) controlled by the PCB.

No. OU No. IU

The following table explains how to programme the outdoor unit numbers. Up to 16 numbers can be programmed: OU No. Pin setting

The following table explains how to programme the numbers of the indoor units controlled for each board: HARC-BX (A) Indoor units from 0 to 7 (8 IU) Pin setting Indoor units from 0 to 3 (4 IU) HARC-BX (B) Pin setting
from 4 to 7 (4 IU) from 8 to 11 (4 IU)

from 8 to 15 (8 IU)

from 12 to 15 (4 IU)

Tab. 13

The position of the switch indicates the address of the first indoor unit for this group of 8 units in the case of the HARCBX(A) or the first indoor unit for the group of 4 units in the case of the HARC-BX(B). Only the address indicated in the table above can be used for each group. 5. et the 8 pin DIP switch (S202) S The 8 pin DIP switch (S202) is used as follows:

Board not activated

Activate the board to control a given number of indoor units based on S201

Board active as slave

Board active master (only one board can be a master board on each H-Link line)
Test Mode for the activated board (see section 4.1.3.1 for further details)

This is a step-by-step guide to enabling additional functions on Hitachi Utopia and SetFree products via the standard PC-P2HTE or PC-ART remote controller
Instruction 1) Ensure Remote Controller is OFF 2) Press OK and RESET together for more than three seconds
Status Service Mode status 01 will appear in the bottom window.
Service Mode 01 is what we need to enter in order to set up optional functions. 3) Press OK Address will show in top window.
The first 00 digits represent the indoor unit address. The second 00 digits represent the outdoor (Refrigerant Number) unit address. 4) Press the Temperature Down button once Address display in top window will change from to AA AA (all units) This setting is the most advisable when doing any modification. You would only select a specific indoor unit if you were commissioning a large group of units, such as a number of fan coils on a VRF system.
5) Press OK Optional setting B1 will appear in top right window. The AA AA display will be replaced by 00 status.
6) Press SCHEDULE continuously to scroll through to required function code, in this case, B8 Automatic Cool/Heat Operation
Indication B8 will appear in top right window. (B8 is the Indication for Auto. 00 is the status which is Auto Operation - OFF.)
7) Press OK This will scroll through the required optional setting for B8 Automatic Cool/Heat Operation 00 Auto Mode not available 01 Auto Mode available (See page 3 for full list of functions) 8) Press RESET
Status 00 will change to 01. 01 is Auto Mode available
Remote controller will return to normal operation mode.
9) Turn remote controller ON
Normal Operation. (For this example, press MODE button to ensure AUTO operation is working)
10) Repeat above instruction, this time selecting mode B1. Mode B1 will eliminate the factory set heating temperature offset of 4C.
