8.4 Offset Function HRZ Series
When MODE2 is selected
With OFFSET value set at -1deg C, TEMP PV and communication data express
“29deg C” (circulating fluid discharge temp. value + OFFSET value) that agrees
with the temperature of the circulating fluid in your system.
Figure 8-7 When MODE2 is selected
When MODE3 is selected
This mode enables this system to exercise temperature control to obtain 31deg C
(TEMP SP value +OFFSET value), with OFFSET value set at 1deg C. Once the
discharge temperature of the circulating fluid becomes 31deg C, 1deg C-thermal
dissipation is assured to allow the circulating fluid in your system to be 30deg C.
TEMP SP value is obtained for your system. TEMP PV and communication data
also express “30deg C” (circulating fluid discharge temp. value - OFFSET value)
that agrees with the temperature of the circulating fluid in your system.
