Product description: Overall description

Product description

Overall description

The CC 3000 is designed as a single board controller, including all connections needed to sup-

port free cooling products with or without additional air conditioner. The CC3000 controller is

enclosed in a special designed plastic casing, with UL rating 94-V0, dedicated for wall mount.

Embedded micro controller is a 32 bit Cortex M3 core.

The CC 3000 controller supports basic temperature and relative humidity control in enclo-

sures - always attempting to minimize energy consumption.

The controller is able to operate following equipment simultaneously:

• two free cooling units

• two motorized exhaust dampers/TC damper

• two AC/DC air conditioners (via 0-24 V DC output)

• one heater (via another 0-24 V DC output)

This illustrates the dierent parts of the CC 3000 controller.

Product description: System operation strategy

System operation strategy

This section describes the operation strategy according to the possible operation modes: Free

cooling mode, Standard mode, Energy save mode and Air Con mode.

The basic operation strategy of the CC 3000 can be described in the following way:

• Connected heater (optional) starts, when temperature is too low (on/o set points for

heater can be adjusted).

• Free cooling unit(s) start(s) up slowly, when temperature rises above Min °C set point and

fan will increase speed gradually (according to P-band) until Max °C set point is reached.

• P-band starts at Min °C set point and stops at Max °C set point.

• Most setups will only need a P-band, which continues from Min °C to Max °C without

interruption. The set point for Mid1and Mid2will in this case be exactly the same.

• The P-band can be separated into two parts, interrupted by Mid1and Mid2as illustrated

in Fig. 4.

• Air Conditioner(s) is/are activated, when the set point for A/C on is reached and stops

again, when temperature drops below set point for A/C o.

• Emergency operation is a special boost operation, where all connected cooling units

(both free cooling and A/C) starts up at the same time, until temperature drops below

emergency o.

Fig. 4

This table describes the diferent settings, which can be adjusted with the CC 3000 controller.

Default values for the above set points can be found in the manual for the free cooling unit.

Introduction

Generic example

Product description: System operation strategy

Use of free cooling unit(s) only. Free cooling unit will increase/ decrease fan speed gradually

between Min °C and Max °C.

Fig. 5

Free cooling unit starts when outdoor temperature is min. 3 °C colder than set point. If out-

door temperature is closer to or above set point and cooling is needed, A/C unit will operate

on its own.

Fig. 6

Free cooling mode

(default)

Standard mode

Product description: System operation strategy

Free cooling unit starts when outdoor temperature is min. 1 °C colder than indoor tempera-

ture. If outdoor temperature is closer to or above set point and cooling is needed, A/C unit

will operate on its own.

The free cooling unit is not active. Only the connected Air conditioner is operating.

In case the digital inputs are used together with external transducers like a re/ smoke alarm,

it may be necessary to change the input from normally opened (NO) to normally closed (NC).

The only way to do this is via the conguration le. Follow these steps:

Pos. Action Illustration

1 Put SD card into your PC SD card reader.

2 Open the .txt le with the le name that match your product.

• The .txt le can be opened with wordpad

3 Go to system control conguration section and change line 57/58/59 to match your

requirement:

• 57.Dig.1 NO/NC Type [0/1]: 0

• 58.Dig.2 NO/NC Type [0/1]: 0

• 59.Dig.3 NO/NC Type [0/1]: 0

Note: (NO=0 NC=1)

4 When required change is done, save and close the le.

5 Insert the SD card into the controller.
