Once the discharge temperature of the circulating fluid becomes 31C, 1C-thermal dissipation is assured to allow the circulating fluid in your system to be 30C. TEMP SP value is obtained for your system. TEMP PV and communication data also express 30C (circulating fluid discharge temp. value OFFSET value) that agrees with the temperature of the circulating fluid in your system.
