3.5 Components
Fig. 3-3: Components
1Casing
The casing design gives the unit a high level of air tightness. The side and rear panels
are flat and are flush with the edge of the frame. The front doors are removable during
servicing. All doors use a compression locking mechanism to give a high quality seal.
The frame rails are anodised aluminium and the panels are white PVC coated steel.
Other panel colours are available on request.
2 Touch screen display
A colour touch screen display is mounted into one of the front doors of the unit (stan-
dard configuration). Settings are separated into three levels allowing for control of sys-
tem settings based on passwords. The display is able to switch between several
languages and alarms are displayed in plain text.
The display has a screen saver function, which changes to signify when there is an
alarm present.
3 Microprocessor control
The microprocessor can control all the functions for cooling, heating, humidifying and
dehumidifying. It can monitor all digital and analogue inputs and outputs and can be
linked in a network between units. The C5-12 controller can output to the BMS stan-
dard RS485, but other BMS interfaces can be installed into the controller.
As an additional option, the C5-12 controller can be fitted with an UPS capacitor to
enabling the powering of the controls for over 1 minute during a power outage. This
feature removes the start-up time of the unit when the power supply is restored.
4 Cooling coil
The cooling coil is inclined within the unit and uses copper tubes and rippled aluminium
fins to give high performance. To prevent condensed water entering the supply air, an
intermediate drip tray collects water that drains to a larger drip tray, which is mounted
to the bottom of the coil.
