t time
By setting the time bands and setting the light as the switched output (H8 = 0), the set point follows the day/night settings of
the time bands:
t
night
tS1
day
tE1
tS2 tE2 tS8 tE8
Fig. 7.m
During day status:
• Set point = St
• control probe Sv
• light or AUX output on, depending on parameter H8
During night status:
• Set point= St + r4
• Control probe Sv or Sr, depending on the value of r6a
• light or AUX output off , depending on parameter H8
7.8 ECO operation
During ECO operation, the iJW uses the same control set point St+r4, but with a diff erent diff erential. This reduces the number
of compressor starts/stops and reduces energy consumption. ECO operation can be activated on the user interface or from the
supervisor, with the same priority.
Notice: the time bands for ECO operation and night operation are the same; the action depends on the setting of param-
eters r4 and r4d.
