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.

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.
