OWNER’S AND INSTALLATION MANUAL
Inverter Condensing Unit Control Module
FRIAHUKZ-LCAC-01
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-01 cont rol module enables t o control inverter type outdoor
unit without the needs of aircondit ioner fact ory produced indoor unit . It
gives possibilit y t o cont rol out door unit capacit y and st at e t o
produce heat or cooling for AHU or w at er heat er/ cooler.
FRIAHUKZ-LCAC-01 cont rol module enables to control invert er condensing unit
capacit y bet w een 0 – 10%~100% by ext ernal input 0~10VDC signal.
Dry contact signal is used to cont rol outdoor unit to work in cooling or heat
ing mode.
The installat ion and operat ion of outdoor unit as well cont roller must be
done according to t he manuals (i.e. User ‘s manual, Installat ion manual,
Technical Specificat ion, Service M anual).

Function and Setting
Connection Terminal Introduction:
L, N, S– -Power Supply and communicat ion w it h outdoor unit
230V,1-phase, 50Hz. Cable dimension 3×1.0 mm2.
ALARM —digit al out put 5A-250VAC or 5A-30VDC. W hen outdoor unit has
malfunct ion signal is act ivated.
DEFROST- –digit al out put 5A-250VAC or 5A-30VDC. When outdoor unit is in
defrost mode is act ivated.
TEM P1- — T2 temp sensor (evaporator coil temperat ure sensor) terminal.
Temp sensor must be placed at middle of heat changer.
0-10V– -Analog input terminal to cont rol 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, t he unit w ill run in
heat ing mode and ” HEAT” LED w ill be on.Terminal C is Posit ive(+) and
terminal D is Negat ive(-)
Note: Terminal B and D are connected as one Negat ive(-), so 3 cables to
cont rol cooling/ heat ing are feasible.
ENC1 – knob for mult i split connect ion to select indoor unit capacit y.
This knob is for mult i indoor unit s connect ion only. This knob w ill not
work at one indoor to one outdoor connect ion.
| Knob selection | Indoor unit capacity |
|---|---|
| 0 | 2,0 kW unit |
| 1 | 2,6 kW unit |
| 2 | 3,2kW unit |
| 3 | 3,5 kW unit |
| 4 | 5,3 kW unit |
| 5 | 7,1 kW unit |
| 6 | 7,1 kW unit |
| 7 | 9,0 kW unit |
| 8 | 10,5 kW unit |
| 9 | 14,0 kW unit |
| A-F | 16,0 kW unit |
