JEA USER MANUAL
sollateksupport@sollatek.com I 19
The JEA will take the cooler pattern and then switch into DAY mode from NIGHT mode 3 hours (6 slots) earlier than the learning
pattern.
5.2.2.4 Software Irregularities Filtration:
A software filter is added to change periods of NIGHT less than the Look-Ahead value to DAY in order to overcome
irregularities.
For example, Look-Ahead = 6, then if the 24-hour array is found to be:
[D D D D N N N N N N D D D] this will be changed to [D D D D D D D D D D D D D]. Every 24 hour the filter will be applied to
the 24-hour array elements that has been saved.
5.2.3 DOOR SWITCH FAILURE
In the event of a door switch failure, the JEA will stop updating its learning pattern based on the cooler usage and will remain in
DAY mode until the failure has been rectified.
After the door switch operation is restored (failure has been rectified), then the unit will reset its learning pattern and will start
the learning process from the beginning.
5.3 PROTECTIVE DELAYS
5.3.1 TEMPERATURE BLIND TIME
The software will ignore the sensor temperature reading for the first few seconds (a pre-set value of 10 seconds) after the
compressor is switched on. This is to prevent short-term thermal effects such as those caused by the fan starting to operate
causing disconnection.
