The cool (warm) air does not
come out of the product.
• Check if the set point temperature of the connected air conditioner is higher (lower) than
the current temperature.
• Check if the product has just been turned on. If so, wait 3 minutes. Cool air does not come
out to protect the compressor of the outdoor unit.
