 To operate the system on two input contacts using instantaneous input for the input
A and input B
(Use instantaneous input with ON time of 200 msec or more for the input A.)
Cautions

Using normal input for the input B in Positions 7 to A will put the system into forcedly stop
function (with input A disregarded).

In Position B, the normal input cannot be used for the input B.
3. Input of temperature settings
Temperature settings corresponding to resistance values in the range of 0 to 135Ω can be
made.
Caution The resistance values are counted in wiring resistance.

In order to make temperature settings from both remote and remote
controllers, set this switch to "Permitted". (Factory set: Permitted)
Permitted: Use this mode to make temperature settings from both remote
and remote controllers. (Last setting priority control is enabled.)
Inhibited: Use this mode only to make temperature settings from the
remote. (No temperature settings are enabled from the remote
controller.)
