Summer temperature at 20° C
and 30° C outside
The function has a varying alarm limit which follows the changes that occur
in high outside temperatures. When the temperature increases, the alarm
limit also increases. It therefore delays the time at which the high
temperature alarm will be generated.
The DOL 53X controller generates the alarm only if the inside temperature
also exceeds the high temperature alarm.
Absolute high temperature
The alarm for absolute high temperature is generated by the actual
temperature, e.g. 32° C. DOL 53X will generate the absolutely high
temperature alarm when the inside temperature exceeds this setting.
Alarm for Absolute high temperature is
set like a temperature curve.
Temperature difference
between front and rear zones
(2 zones)
The alarm is active at Tunnel ventilation where ventilation is regulated
according to an average value of the front and rear temperatures. DOL 53X
generates an alarm when the temperature difference between the front and
rear zones exceeds the set number of degrees.
