HRZD Series 8.4 Offset Function
8-15
When MODE2 is selected
With OFFSET value set at -1°C, TEMP PV and communication data shows
“29°C” (circulating fluid discharge temp. value + OFFSET value) that agrees with
the temperature of the circulating fluid in your system.
Figure 8-5 When MODE2 is selected
When MODE3 is selected
This mode enables this product to exercise temperature control to obtain 31°C
(TEMP SP value +OFFSET value), with OFFSET value set at 1°C. Once the
discharge temperature of the circulating fluid becomes 31°C, 1°C-thermal
dissipation is occurs to allow the circulating fluid in your system to be 30°C.
TEMP SP value is obtained for your system. TEMP PV and communication data
also express “30°C” (circulating fluid discharge temp. value - OFFSET value) that
agrees with the temperature of the circulating fluid in your system.
