• Do not install the zone controller in outdoor location as it is designed for indoor installation only. (The zone controller circuit board and casing are not waterproof.)
• Avoid locations where the zone contoroller is exposed to direct sunlight or other sources of heat.
• Select a location where easy wiring access to the power source is available.
• Avoid locations where combustible gases may leak, be produced, flow, or accumulate.
• Select a level location that can bear the weight and prevent vibration of the zone contoroller.
• Avoid locations where the zone contoroller is exposed to oil, steam, or sulfuric gas.
• Do not install in location that ambient temperature exceeds 60°C and relative humidity exceeds 80%.
• Do not install zone control interface on top of the indoor unit.
