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).
