Name
Thermal Cooling/Heating
Switching Boost Temp
Band/PID Sets a boost band for normal PID operation and when using thermal actuators. The variables indicate a
Boost setpoint-space temperature deviation outside which the outputs are switched to full operation to act as a boost
function when space temperature deviates significantly from the desired setpoint. These values also serve as a
threshold for two-point switching of thermal actuators.
• The threshold can be set in the range 0 to 10 DDC (7.2 to 180 DDF).
• If the threshold is set to 0 DDC, the boost function is disabled.
