VII. CHARTS WHICH PRESENT OPERATION OF PARTICULAR
ELEMENTS OF THE UNIT
Thick line means that the unit is on and interrupted line means that the unit is off.
The square ‘stop’ means that the compressor is off and ‘operation’ that it is on because programmed
temperature has been exceeded, taking into account the value of programmed hysteresis parameter ‘d3’.
