3. Input of temperature settings
Temperature settings corresponding to resistance values in the range of 0 to 135
Ω
can be
made.
Caution The resistance values are counted in wiring resistance.
4. Fetch of display signals
Normal operation output terminals (W1 and W2) and malfunction output terminals (W3 and
W4) are used for no-voltage normal contact output.
(Allowable current is 10mA to 3A per contact.)
Caution In order to use power supply of AC220 ~ 240V, keep the power supply cable away from input
wirings.
In order to make temperature settings from both distant and
remote controller, set this switch to "Permitted". (Factory set:
Permitted)
Permitted: Use this mode to make temperature settings from
both distant and remote controllers. (Last setting
priority control is enabled.)
Inhibited: Use this mode only to make temperature settings
from the distant control. (No temperature settings are
enabled from the remote controller.)
NEVER apply voltage to terminals A+ or A
