Individual cooling units communicate directly with each other via the CoolBus communication bus, allowing the Coolsure UTS system to be fully functional without requiring the CCU-03 to be connected. The CCU-03 can thus be used either as a service tool for the Coolsure UTS system to adjust setpoints and view detailed system parameters for fault finding, or can be permanently installed at the site to provide remote alarm capability and enhanced system features. This User Manual describes the features and operation of the CCU-03 Central Control Unit. CCU-03 User Manual R2 UTS+ECS Page 3 www.coolsure.com 3/9/2011 up. down.

The Control Unit is powered redundantly by the airconditioning units and/or fan/filter unit via the CoolBus. Ordinarily the LED should flash a few times per second. with the observation alarm being the lowest alarm level and the critical alarm being the highest alarm level. Each alarm can be set to any one of the alarm levels. In the case of intentionally removing a unit from the system. • In order to provide failsafe system monitoring. this alarm can be reset by re-initializing the number of units in the Central Control Unit (Section 4.8.coolsure.com 3/9/2011 .

Adding a new airconditioning unit to the system: • New airconditioning units can be connected to the CoolBus while the system is running • New units are automatically detected and integrated into the system by the existing airconditioning units and Central Control Unit. providing redundant operation. The other airconditioning units automatically adjust to the loss of a unit from the CoolBus. This ensures that an alarm is generated in the case that a unit has failed in such a way that it is unable to send a fault alarm to the Central Control Unit. these need to be adjusted via the Central Control Unit (see Setting Menu) Removing a unit from the system: • Typically the loss of a unit from the CoolBus is indicative of a fault in the unit.Coolsure Limited • • If either a airconditioning unit or a fan/filter unit is turned on.5. the Central Control Unit should be powered and able monitor the system The green “Communication LED” should flash to indicate communication on the CoolBus – failure of the LED to flash indicates a problem with the CoolBus connection. the Central Control Unit generates a “Unit Lost” alarm if a unit from the system for a certain length of time (Section 4. if the update is cancelled at or before the last parameter. it enters to update mode and the target parameter should be flashing.

A higher than Normal setpoint can be used to minimise the airconditioner power consumption when running from battery.4. Figure 3.1-1 Normal Setpoint in Setpoint Menu N o r m a l S e t p o i n 2 8 . see Appendix B.coolsure.Coolsure Limited 4. This feature can also be used for other cases whereby different setpoints are desired for different periods of the day – for example a higher setpoint could be chosen for night-time to minimise noise and disturbance to nearby residents. This feature requires the Central Control Unit to be connected to the system as the Setback period and realtime clock are contained in the Central Control Unit. The system setpoints can be edited via the Central Control Unit and are updated in each individual airconditioning unit and fan/filter unit upon acceptance (by pressing the enter key) of the edited value.5. For more information about the setting range and factory default setting. After editing.com 3/9/2011 . The setpoints in each airconditioning unit and fan/filter unit should ordinarily be identical for correct system operation.1 Setpoint Menu The various system setpoints are stored in each individual airconditioning unit and fan/filter unit. but adding a new airconditioning unit to the system can result in units with different setpoints. • Backup Setpoint This is the temperature setpoint when the unit is running on battery. 4. • Setback Setpoint This is the temperature setpoint during the setback period.The lower temperature difference between indoor and outdoor can minimize the airconditioner power CCU-03 User Manual R2 UTS+ECS Page 10 www. An example screen is shown in Figure 3. The system maintains the room temperature according to this setpoint in Setback Mode. Setback mode is ordinarily used to provide a higher system temperature (with corresponding reduced airconditioner power consumption) during periods of higher energy cost. All parameters in this menu can be updated. The Normal setpoint is usually chosen to provide an optimum tradeoff between airconditioner power consumption and telecom equipment and battery life.5 Settings Menu This menu is used to change the system setting.1-1. The system would maintain the room temperature according to this setpoint in Normal Mode. with the Normal and Setback temperatures chosen such that the average system temperature will be maintained at the desired level.4. and the Central Control Unit displays the average value stored in the units. allowing one to check that the value has been correctly updated. • Track Delta The airconditioning units are capable of adjusting their setpoint with the outdoor ambient. hence minimising the impact on the battery backup capacity. The system maintains the room temperature according to this setpoint in Backup Mode. Outdoor ambient to the telecom station might relatively varies indoor temperature . (i. the compressor will be switched on). In other words. setpoint varies between 23C and 27C with ambient temp. • UTS Capacity This feature can be utilised to limit the total system cooling capacity (and hence input power consumption). However. if the ambient dropped below its average by 1C. the return temperature is measured adjacent to the indoor unit heatexchanger. Hence. the compressor will be switched off. • Humidity Setpt (Feature is currently not implemented) (This item is applicable only when the T-1C/TRH-2C is connected) CCU-03 User Manual R2 UTS+ECS Page 11 www. With setpoint of 25C and track delta of 2C. This is a delta value applied on the temperature setpoint which limited its linear variation with outdoor ambient. if return temperature < setpoint – delta. In this case the units switch into an on/off control mode in order to maintain the room temperature equal to the setpoint. A unit provides no cooling capacity when its compressor is turned off and operating its indoor fan causes avoidable power losses.2 x (70 + 70) = 154Hz. under light load conditions.) The Capacity Limit can be adjusted between 50% and 200%. 51Hz each if they are all working. if the return temperature > setpoint + delta. meaning some airflow is desirable to ensure the air temperature is sampled correctly. the setpoint becomes 24C. such as a diesel generator or fuel cell. it may be desirable to have continued indoor airflow even when the compressor is turned off. With 3 units in the system(one redundant) and power limit of 120%. but more frequently cycling of the compressors and increased energy consumption. This factor can effectively control the maximum compressor speed. or limited capacity AC feed.5C to 2.e. For example. sum of the compressor speeds should be 1. Too low a value leads to more accurate temperature control. However.com 3/9/2011 . Capacity Limit is a factor (in percentage) on the rated total operating speed (assumed one unit is redundant when more than one unit are connected). the airconditioning unit may still provide too much cooling capacity at minimum compressor speed (20Hz).e. (i.) This feature can be disabled by setting the value to zero.coolsure. Units automatically determine which compressor should be turned off/on in order to equalize run-time between the different units.0C.Coolsure Limited consumption – for example setpoint will be higher during the daytime since the ambient temperature will be raised. This can be useful in the case the system is connected to a limited capacity supply.e. The cooling capacity is originated in compressor operating speed. limiting the operating speed can control the input power consumption. (i. The fan speed can be adjusted linearly between 40% and 100% with a minimum fan speed of 40%. This is a delta value on the temperature setpoint which provides hysteresis on switching on/off the compressor. Normally this value should be in the range of 0. in some cases. A setpoint between 0 and 40 results in an indoor fan speed of 0% when the compressor is turned off.
