2.1.2 Other temperature functions
The high and low temperature alarms cause alarm screen signalling and have modifiable delay time.
The dehumidification stop differential establishes the minimum temperature below which dehumidification is
interrupted. Dehumidification can start again if temperature returns above the value established by the
humidification start offset; differential and offset are modifiable.
