System function introduction

E02A INTEGRATED RACK TYPE AIR CONDITIONER

   UM.ICUBE2.0-IRTAC.SG.0822   August 2022   www.eaton.com

4.  System function introduction

The operation of the air conditioner is automatically controlled according to the temperature inside the cabinet. The 

controller detects the return air temperature by temperature sensor and compares it with the set point to judge, 

and then controls the compressor or fan.

4.1  Cooling

Cooling stop point=cooling set point cooling Delta T. When the rack internal temperature exceeds the cooling set 

point (CoolingSP), the cooling will start; when the cabinet internal temperature is lower than the cooling stop 

point, the cooling stops.

Parameter

Default value

Setting range

CoolSP

29˚C

[20~50]

Cool T

3˚C

[1~10]

INHT

65˚C

[20~80]

Setting point descriptione:

CoolSP: Set point when cooling starts.
Cool T: Temperature control sensitivity.
INHT: Internal high Temp. alarm point.

   CAUTION!

For the reliable operation of the unit and the maximum energy efficiency, it is recommended that the user 

should not randomly change the temperature set point.

4.2  Heating (Option)

Heating stop point=heating point+heating sensitivity. When the temperature inside the cabinet is lower than the 

heating start-up point, the heating will start; when the temperature inside the cabinet is higher than the heating 

stop point, the heating will stop.

Parameters

Default value

Setting range

HeatSP

0˚C

[-5~15]

Heat T

10˚C

[1~15]

Setting point descriptione: 

HeatSP: Point when heating starts. 

Cool T: Temperature control sensitivity.

   CAUTION!

For the reliable operation of the unit and the maximum energy efficiency, it is recommended that the users 

should not randomly change the temperature set point.
