Power and Communication Wiring
Important: The current display is designed to control only 1 rooftop unit.
It is imperative to respect wiring of the power supply and of the communication according to the scheme below to
guarantee correct function of the thermostat.

Apply 120 Ω terminal resistance (not included in the packaging) between terminal + (13)
& - (14), if end device of serial RS 485 Bus, when a communication cable is longer than 200 m.
Maximal length of the communication and power cables is 500 m.
It is needed to set a communication type in Service display. There is “None” by default.
