2. Keep pushing the push-switch SW04 on the interface P.C. board for 1 second or more.
The mode changes to the TO sensor value fix manual mode.
3. As shown in the following table, TO sensor value can be fixed by setting the rotary switch SW02 on the
interface P.C. board.

8-7-10. Manual Adjustment Function of Outside Temp (TO) Sensor
This function is provided to fix TO sensor value manually by the switch operation on the interface P.C. board in

able by set up the value manually to position near the current outside temperature.
[Operation]
1. Set the rotary switches on the interface P.C. board to numbers as follows.
• SW01 [2] / SW02 [1] / SW03 [15]
• 7-segment display: [t o]
