3-Bit Remote 1 Cycle Value. These three bits define the delay time between making subsequent TMIN  
adjustments in the control loop for the Remote 1 channel in terms of 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.

3-Bit Local Temperature Cycle Value. These three bits define the delay time between making  
subsequent TMIN adjustments in the control loop for the local temperature channel in terms of  
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.

CYR2  
2 LSBs of 3-Bit Remote 2 Cycle Value. The MSB of the 3-bit code resides in the Dynamic TMIN Control  
Register 1 (Register 0x8E). These three bits define the delay time between making subsequent TMIN  
adjustments in the control loop for the Remote 2 channel in terms of 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.
