To make sure you are getting good temperature control use the following guidelines.

Set the dial for the manual heater temperature safety limit to 150 – 180 °F (65.5 - 82.2 °C)

Set the temperature control points on the setup screen.

Set the RUN mode Resin temperature to the desired resin temp. Typically 90 – 110 °F (32 - 43.3 °C)

Set the Run Mode Maximum Fluid Temp to a point higher than the resin set temp to allow it to heat the resin. Typically 10-20 °F (-12.2 to -6.67 °C) above the resin set temp.

Set the Recirc Mode Resin temp to a reasonable good starting temperature. Typically 70 – 80 °F (21.1 - 26.7 °C)

Set the Recirc Mode Fluid Maximum Temperature to the same or slightly higher temperature as the resin recirc set temp. There is such a short loop for recirculation that it doesn’t take much to maintain a resin temperature during recirc. If you re-plumb the resin recirc to return to the tote instead of the pump to allow preheating of the tote the maximum fluid temp should be raised to about 5 – 15 °F (-15 to -9.4 °C) above the resin set temp.
