Loop3 Run Temperature Setpoint Value Used when bit 2 of word 10 is on (0 thru 999.9
).
13 0-15 Loop3 Manual Output Value (CV) Used when bit 1 of word 10 is off (-100.00 thru +100.00).

0 Loop4 Enable
•0 = Loop 4 disabled.
•1 = Loop 4 enabled if PID control mode selected (bits 7-8, word 2, config block).
1 Loop4 Auto/Manual Mode Select
•0 = Loop 4 is in the manual mode the manual output value (from word 17) is used as the CV value.
•1 = Loop 4 is in the automatic mode the PID algorithm generates the CV value.
2 Loop4 SetPoint Select
•0 = Select the standbytemperature setpoint value from word 15.
•1 = Select the runtemperature setpoint value from word 16.
3 Loop4 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 Loop4 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 Always = 0.
