2 LSBs of 3−bit remote 2 cycle value. The MSB of the 3−bit code resides in Dynamic T
Control Register 1 (Register 0x36). These three bits define the delay time between making
subsequent T
number of monitoring cycles. The system has associated thermal time constants that need to
be found to optimize the response of fans and the control loop.
