8.4 Offset Function

With OFFSET value set at -1°C, TEMP PV and communication data express
"29°C" (circulating fluid discharge temp. value + OFFSET value) that agrees with
the temperature of the circulating fluid in your system.

This mode enables this system 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 assured 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.
