Description of the Air Handling Unit
Control Schedule
Diagrammatic description of the control functions, GOLD CX
The built-in control system controls and regulates temper-
atures, airflows, in-operation periods and a large number
of internal and external functions.
In that it is a microprocessor-based system, it can solve
highly complicated tasks. The specific components are
outlined below each individually in a simplified and sche-
matic specification.
BT3 Temperature sensor, outdoor air.
BT1 Temperature sensor, supply air. Positioned in
the ductwork.
BT2/BM2 Temperature sensor, extract air/Humidity
sensor, extract air. For anti-frost protection.
T1/T2 Motor control system for variable speed
control of the fan motors.
BF1/BF2 Pressure transducer. Indicates for controlling
the fan speed so that the preset airflow will be
maintained.
BP1/BP2 Pressure transducer for checking the filter
status.
BT6 Temperature sensor, coil heat exchangers. For
anti-frost protection.
GOLD CX, sizes 100/120: Pipework package including control box are supplied in unmounted condition for floor or wall mounting (accessories).
