Operating Data
CONTROL - GENERAL
The microprocessor controller has been specifically designed to provide the
control information necessary to operate the unit in an energy efficient manner.
An optional real time clock (RTC) offers energy savings and will time / date stamp alarms.
The unit will operate in 1 of 4 modes:
1 Free Cooling - using outside air only
2 Free Cooling and DX Cooling - using outside air and DX cooling
3 DX Cooling - mechanical cooling with room return air
4 Electric Heating (Optional Extra)
FULL FREE COOLING
When the outside ambient temperature is low enough the fresh air damper will modulate
between 0-100% using full fresh air to cool the room.
As a further consideration to energy efficiency, the condenser fan is off during full free
cooling mode.
FREE COOLING & DX
COOLING
The controller will call for free cooling when the outdoor air temperature sensor senses
the temperature of the outside air 2C below the return air temperature. The
microprocessor will then command the fresh air damper to open and modulate to satisfy
the cooling load in the exchange. Until the external ambient drops low enough, the fresh
air may not be capable of satisfying the cooling requirement of the room and DX cooling
may also be required on an intermittent basis.
When the ambient is low enough and free cooling can totally satisfy the cooling
requirement of the exchange, the damper will modulate to maintain the design room set
point with just the supply fan operating. On low supply temperatures, the damper will
modulate closed.
MECHANICAL DX
COOLING
When free cooling is unable to provide 100% cooling, the DX cooling system will maintain
the temperature in the room.
ELECTRIC HEATING
(OPTIONAL EXTRA)
When heating is required, the unit will control as follows:
When the return air temperature drops belowthe room set point, the
microprocessor will select the stage of electric heating to satisfy the heating requirement of the
room. Once the room conditions have been satisfied, the electric heating will turn offto leave
just the indoor fan re-circulating the room air.
DAMPER POSITION
The minimum set point for the fresh air damper is fully adjustable via the optional
display keypad.
In the event of a fire alarm signal (from the master BMS system), the damper will be
driven shut and the unit will switch off.
