10. Setting Terminator Status

 The terminating resistance of the indoor/outdoor operation lines should have 1 location set to "with resistance" [SHORT]
if there is 1 refrigerant system. If there are 2 or more refrigerant systems, set 2 locations to "with resistance" [SHORT]. If
2 locations are set to "with resistance", set the 2 terminating resistances for the outdoor unit nearest to the central control
device, and for the one furthest away, to "with resistance" [SHORT], and all other outdoor units to "without resistance"
[OPEN]. This is to stabilize communications. Setting 3 or more locations to "with resistance" is prohibited.
 If the terminating resistance of an outdoor unit for a multi-system of U-20GES3E5 and U-10MES2E8 is set to "with
resistance" [SHORT], set the outdoor unit of the gas heat pump air conditioner to "with resistance" [SHORT], and set the
outdoor unit of the U-10MES2E8 to "without resistance" [OPEN].
