The LOW-LIMIT step intervenes during dehumidification as follows:
- if within one minute from the indication of lower limit of the heating differential (-
85%) the temperature values are not comprised within the regulation differential
(-85% _-15%) the LOW-LIMIT step is activated and dehumidification stopped.
- the step remains active up to -15% of the heating differential, then dehumidification
will restart only if required.
2.6 HUMIDITY CONTROL DIAGRAMS
FEATURES:
The type of control can be selected through the dedicated mask (mask SR1U within
the "PROBE MANAGEMENT" branch)
DEHUMIDIFICATION can be achieved:
- by starting one compressor (chosen in the DEU mask within the "Compressors
Management" branch);
- through partialisation of cold water valve (chosen in the GUMI1DEU mask within
the "Compressors Management" branch);
- through fan reduction speed (chosen in the GUMI2DEU mask within the
"Compressors Management” branch);
- Dehumidification is enabled only if ambient temperature is within the alarm limits.
IN CASE OF OUT-OF-RANGE TEMPERATURE VALUES DEHUMIDIFICATION IS
PREVENTED (see diagrams of temperature control).
