Not available if Heating/Cooling control output or External setting input is selected from the Block
function (Console software).
To proceed to CH2 parameter group, follow the procedures below.
(1)
Press the
key 3 times in the PV/SV display mode. The unit will proceed to the CH2
parameter group
(2)
Press the
key. Control Allowed/Prohibited will appear.

Control Allowed/Prohibited
Control Allowed
• Selects Control Allowed/Prohibited.
When Control Prohibited is selected, the unit reverts to the PV/SV display mode by

: Control Prohibited
Auto/Manual control

: Manual control
Manual control MV
• Sets manual control MV.
MV of the automatic
control
If the
is pressed after the manual control MV has been set, the unit will revert to the
PV/SV display mode.
Not available if automatic control is selected.
Default value of manual control is the MV of the automatic control. (After the power is
turned on, the previously set MV will be used.)
• Setting range: CH2 output low limit to CH2 output high limit
AT/Auto-reset Perform/Cancel
AT/Auto-reset Cancel
• Selects AT Perform/Cancel or Auto-reset Perform/Cancel.
• If the AT is cancelled during the process, P, I, D and ARW values revert to the previous
value at which AT was performed.
• AT will be forced to stop if it has not been completed within 4 hours.
• Auto-reset can be performed when P (I=0, D=0) or PD (I=0) is control action.
Auto-reset is finished in approximately 4 minutes. It cannot be released while performing
this function.
