boards to ON.
(Factory setting: OFF)
6. Supply air thermistor is built in on the inside of the indoor unit.
A jumper is taped inside the control box without it being connected to the connector.
Plug the jumper into CN20 on No. 1 circuit board when using the supply air temperature to control the
room temperature. Turn SW7-2 of both No. 1 and No. 2 circuit boards on the indoor unit to ON.
