7.2 SUPPLY AIR TEMPERATURE CONTROL (LIMIT)
7.2.1 µAC MICROPROCESSOR
With the µAC microprocessor control it is possible to install a supply sensor (limit) for display of the supply
temperature and control of the relative low supply temperature alarm.
Below the set limit, the cold components will be progressively deactivated at temperature intervals of 3 °C. In
dehumidification, low supply temperature control is not available.
7.2.2 pCO MICROPROCESSOR CONTROL
With the pCO microprocessor control, high and low supply temperature management is effected by way of
various types of control in accordance with system requirements.
High temperature can be controlled in the following ways:
• ALARM ONLY: after the time delay, an alarm is generated
• STOP HOT: when the alarm threshold is exceeded, the hot component is deactivated; if, after the time
delay, the temperature has still not fallen below the threshold, an alarm is generated.
• HOT + COLD: when the alarm threshold is exceeded, the cold component is activated proportionally
to maintain the temperature below the alarm threshold. If after the time delay the temperature has still
not fallen below the threshold, an alarm is generated.
Low temperature can be controlled in the following ways:
• ALARM ONLY: after the time delay, an alarm is generated
• COLD STOP: when the alarm threshold is exceeded, the cold component is deactivated; if, after the
time delay, the temperature has still not risen above the threshold, an alarm is generated.
• HOT + COLD: when the temperature exceeds the alarm threshold, the hot component is activated
proportionally to maintain the temperature above the alarm threshold. If after the time delay the
temperature has still not risen above the threshold, an alarm is generated.
