This parameter establishes the percent output transmitted by the control outputs when the
controller is in STOP m ode, or when an error condition occurs such as a PID algorithm
error, A/D error, or open sensor error is detected.

This parameter establishes the percent output transmitted by the COOL control outputs in
a Heating & Cooling controller model when the controller is in STOP mode, or when an
error condition occurs. PV
