8.6.2 Electrical wiring
Connect the cord (8 m) of the remote sensor to THM4 of the indoor printed circuit board.
In case of extending the cord
• In the case that the cord is required to be extended, cut the cord in the middle, connect the extension cord (eld-
supplied; with wire size over 0.3 mm) and use it.
• When using extension cord, connect and extension cord with solder and the soldering part should be isolated electri-
cally so that contact failure may not occur.
• The total length of the cord (including extension cord) should be within 15 m.
CAUTION
• When removing the cover of the sensor box, insert the tip of the at head screwdriver between the upper recess part of the sensor
box and the cover, and remove it.
• Run the sensor cord on a place where the power line or noise will not cause any abnormal operation.
• Check to ensure that the wiring is correctly performed.
• The contact failure may cause incorrect temperature sensing and an abnormal operation.
