Adaptor
4. Temperature setting input
Temperature setting corresponds to resistance values in the range of 0 to 135
Ω
.
Their relationship is as shown below.
Relation between the setting temperature and the resistance are as follows.
Note:
„
The value of resistance includes the resistance of wiring.
„
The setting temperature is limited within the setting range of indoor unit. If you set the temperature outside of the
range by the adaptor, it controls at the nearest setting range.

To enable temperature setting from both the optional controller and remote
controller, set SS2 to "POSSIBLE". (Factory setting: POSSIBLE)
POSSIBLE:
Enables temperature setting by both the optional
controller and remote controller. (Engages individual control.)
IMPOSSIBLE: Enables temperature setting from the optional controller only.
(The remote controller cannot be used to set temperature.)
Never apply voltage to terminals A+
or A- for any reason whatsoever.
