6.6.8 Humidity control settings
No.
Explanation
1701
Humidification differential (this is the difference between switching the humidification on and off).
1702
Dehumidification differential (this is the difference between switching the dehumidification on and off).
1703
Humidity control offset (This changes the humidity control switch-off point. Offset = 0 means that the humidity control
will switch off at the setpoint).
1710
The humidity control can be blocked in several different ways. For example:
• the door is open
• if blocking is active
• in both cases
• not at all
1720
RH alarm active?
1721
Maximal humidity level after which an alarm will be generated.
1722
Minimal humidity level after which an alarm will be generated.
1723
Differential for P1722 and P1723.
1724
Blocking humidity alarm if the door is open?
1725
To prevent a minimum RH alarm being generated too quickly, a time delay can be set. For an alarm to be generated, the
alarm must be too low for at least this period of time.
1726
To prevent a maximum RH alarm being generated too quickly, a time delay can be set. For an alarm to be generated, the
alarm must be too high for at least this period of time.
6.6.9 Temperature alarms settings
No.
Explanation
2001
Should absolute alarm 1 be active? A choice can be made between:
• no alarm
• always
• only during control
The last case will block the alarm when the room is off.
An absolute alarm is an alarm whereby the entered value (P2002 and P2003) is the real temperature. The alarm values
does not depends on the set point.
2002
Absolute maximum temperature where above an alarm will be generated
2003
Absolute minimum temperature where under an alarm will be generated
2004
The delay time for absolute alarm 1. The alarm will only be generated after this time has been expired. If the alarm
situation has been solved during the delay time, no alarm will be generated.
2021
Relative alarm 1 active? A relative alarm is connected to the set point.
A choice can be made between:
• no alarm
• always
• only during control
The last case will block the alarm when the room is off.
2022
Relative maximum temperature where above an alarm will be generated. So the temperature which will be entered here,
should be the differential temperature compared to the set point. If f.i. this value is 5K there will be an alarm as soon as
the temperature is more than 5K above the set point.
2023
Relative minimum temperature where under an alarm will be generated
