3. INTRODUCTION
The SPLIT-AHU Kit 0-10V LNS control module enables to control Single- or
Multisplit outdoor units with L, N, S communication. It allows to control
outdoor unit capacity as well as operation mode (heating or cooling) of an air
handling unit or a DX coil.
The control module enables to control inverter outdoor unit capacity between
0 - 10 % ~ 100 % by external input 0 ~ 10 VDC signal.
Dry contact signal is used to control outdoor unit to work in cooling or
heating mode.
SPLIT-AHU Kit 0-10V LNS have a temperature sensor and provide evaporator
froze protection.
The installation and operation of outdoor unit as well as controller must
be done according to the manuals (i.e. User’s manual, Installation manual,
Technical Specication, Service manual).

9 I Installation and Operating Manual
Connection Terminal Introduction:
L, N, S Power supply and communication with outdoor unit connection
terminal 230 V, 1-phase, 50/60 Hz.
ALARM Digital output 5A - 250 VAC or 5A-30 VDC. When outdoor unit has
malfunction signal is activated.
DEFROST Digital output 5A - 250 VAC or 5A-30 VDC. When outdoor unit is in
defrost mode, signal is activated
TEMP1 Terminal for temperature sensors. The temperature sensor must be
placed at middle of heat exchanger.
0 - 10V Analog input terminal to control outdoor unit capacity.
Pay attention to the polarity 0/- and 10/+
Capacity steps:
0 - 0.5 V 0% (unit stopped)
0.5 - 1.5 V 10 % capacity (LED display digit 1)
1.5 - 2.5 V 20 % capacity (LED display digit 2)
...
9.5 - 10.5 V 100% capacity (LED display digit 10)
Warning! Signal input cannot exceed 10.5 V DC, otherwise it may destroy
this control module.
COOL Digital input. When terminals are closed, the unit is running in
cooling mode and „COOL“ LED is on.
HEAT Digital input. When terminals are closed, the unit is running in
heating mode and „HEAT“ LED is on.
Note: Heating mode has priority. If both COOL and HEAT terminals are
closed, unit will run in HEAT mode.
When there are different operating mode among active indoor
units, the system will operate as follow:
- Heating mode will have the priority.
- Cooling mode and Fan mode will conict to Heating mode.

10 I Installation and Operating Manual
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.

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.
* The reference (Indoor unit) value is used exclusively to determine the
possible combination.
For combination exceeding 100%, the cooling and heating capacities
of each indoor units will be proportionally reduced.
