0 Loop1 Enable
•0 = Loop 1 disabled.
•1 = Loop 1 enabled if PID control mode selected (bits 7-8, word 2, config block).
1 Loop1 Auto/Manual Mode Select
•0 = Loop 1 is in the manual mode the manual output value (from word 5) is used as the CV value.
•1 = Loop 1 is in the automatic mode the PID algorithm generates the CV value.
2 Loop1 SetPoint Select
•0 = Select the standbytemperature setpoint value from word 3.
•1 = Select the runtemperature setpoint value from word 4.
3 Loop1 AutoTuning Enable
•0 = Disable autotuning.
•1 = Enable autotuning autotuning can be invoked by an offtoon transition of bit 1 of word 34.
4 Always = 0.
5 Loop1 PID Integral Term Reset Enable
•0 = Accumulate PID integral term.
•1 = Reset the PID integral term on the 0to1 transition, and then allow accumulation until the next 0to1 transition.
6-15 Not used.

Loop1 Standby Temperature Setpoint Value Used when bit 2 of word 2 is off (0 thru 999.9
).
4 0-15
Loop1 Run Temperature Setpoint Value Used when bit 2 of word 2 is on (0 thru 999.9
).
5 0-15 Loop1 Manual Output Value (CV) Used when bit 1 of word 2 is off (-100.00 thru +100.00).
