IMPORTANT NOTE:
Read this manual carefully before installing or operating your new air
conditioning unit. Make sure to save this manual for future reference
Introduction
FRIAHUKZ-LCAC-02 control module enables to control inverter type outdoor unit without the needs of airconditioner factory produced indoor unit. It gives possibility to control outdoor unit capacity and state to produce heat or cooling for AHU or water heater/cooler.
FRIAHUKZ-LCAC-02 control module enables to control inverter condensing unit capacity between 0 – 10%~100% by external input 0~10VDC signal.
Dry contact signal is used to control outdoor unit to work in cooling or heating mode.
The installation and operation of outdoor unit as well controller must be done according to the manuals (i.e. User’s manual, Installation manual, Technical Specification, Service Manual).

System design
Function and Setting
Connection Terminal Introduction
L, N, S —Power Supply and communication with outdoor unit 230V,1-phase, 50Hz. Cable dimension 3×1.0 mm2.
ALARM —digital output 5A-250VAC or 5A-30VDC. When outdoor unit has malfunction signal is activated.
DEFROST— digital output 5A-250VAC or 5A-30VDC. When outdoor unit is in defrost mode is activated.
TEMP1— T2 temp sensor (evaporator coil temperature sensor) terminal. Temp sensor must be placed at middle of heat changer.
0-10V —Analog input terminal to control outdoor unit capacity.
| Analog input | Capacity output | LED display |
|---|---|---|
| 0-0.5V | 0% | None(Unit stopped) |
| 0.5-1.5V | 10% | digit 1 |
| 1.5-2.5V | 20% | digit 2 |
| 2.5-3.5V | 30% | digit 3 |
| 3.5-4.5V | 40% | digit 4 |
| 4.5-5.5V | 50% | digit 5 |
| 5.5-6.5V | 60% | digit 6 |
| 6.5-7.5V | 70% | digit 7 |
| 7.5-8.5V | 80% | digit 8 |
| 8.5-9.5V | 90% | digit 9 |
| 9.5-10.5V | 100% | digit 10 |
Warning:
Negative(0/-) and Positive(10/+) terminals can not be mixed, otherwise it may
destroy this control module. Signal input can not exceed 10.5VDC, otherwise it
may destroy this control module.
COOL— Digital input. When terminals are closed, the unit will run in
cooling mode and “COOL” LED will be on. Terminal A is Positive(+) and terminal
B is Negative(-)
HEAT —Digital input. When terminals are closed, the unit will run in heating mode and “HEAT” LED will be on. Terminal C is Positive(+) and terminal D is Negative(-)
Note: Terminal B and D are connected as one Negative(-), so 3 cables to control cooling/heating are feasible.
ENC1 – knob for multi split connection to select indoor unit capacity. This knob is for multi indoor units connection only. This knob will not work at one indoor to one outdoor connection.
Knob selection| Indoor unit capacity| Knob selection| Indoor
unit capacity
---|---|---|---
0| 2,0 kW unit| 6| 7,1 kW unit
1| 2,6 kW unit| 7| 9,0 kW unit
2| 3,2kW unit| 8| 10,5 kW unit
3| 3,5 kW unit| 9| 14,0 kW unit
4| 5,3 kW unit| A-F| 16,0 kW unit
5| 7,1 kW unit| |
LED lamps introduction
HEAT LED is lightened when the unit is operating in heating mode.
COOL LED is lightened when the unit is operating in cooling mode.
DEF LED is lightened when unit is in defrost mode
