How to Install the System Controller
Installation site selection
Install the system controller at a height between 1 and 1.5 meters above the floor.
Do not install the system controller in a place where it will be exposed to direct sunlight or near a
window or other place where it will be exposed to the outside air.
Be sure to install the system controller vertically, such as on a wall.
Do not twist the control wiring together with the power wiring or run it through the same
metal conduit, because this may cause a malfunction.
Install the system controller away from sources of electrical noise.
Install a noise filter or take other appropriate action if electrical noise affects the power
supply circuit of the unit.
Do not supply power to the unit or try to operate it until the tubing and wiring to the outdoor
