Write the AT start code “CF00” to the output word of the relevant loop and con-
firm that the input word will become CF00.

To cancel auto-tuning, use the code “CF01” instead and follow the above proce-
dure.
Note
1. To put the Temperature Control Unit into expansion mode, change the jump-
er pin on the side of the Unit from 2 and 3 to 1 and 2.
2. Auto-tuning is not available if the half period exceeds 9999 s (approximately
2 hours 45 minutes). If the half cycle exceeds 9999 s, no measurement is
possible and the Temperature Control Unit will restart auto-tuning automati-
cally.
3. If the output word data is left as CF00, auto-tuning will be repeated. Be sure
to return it to the set value.
3-6-1 Manual Settings (Expansion Mode)
When the Temperature Control Unit is turned ON, the SP will be allocated to the
output word and the PV will be allocated to the PV word. By changing the con-
tents of the allocation, the following six set values can be read or written.
