(Why don't we show the price?)

Retailers have the legal right to set their own prices, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's “minimum advertised price,” the manufacturer does not allow us to show you our price until you place the item in your cart, or in some cases, proceeding to the final checkout stage. Taking these steps allows Appliances Connection to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products. You are not required to purchase the product to see our lowest price, simply just remove it from your cart.

Power Cord
Factory supplied power cord with 3-prong grounding plug and current detection device with reset.

Memory function to keep unit settings
Upon a power failure all of the settings are stored. When the power is restored the unit will re-start in the mode in which it was previously set. This function eliminates all discomfort during unattended sleep operation.

Compressor restart delay
Prevents short-cycling the compressor and to extend the overall life of the air conditioner. There is a 3 minute delay to equalize refrigerant pressures for optimizing cycling.

Evaporator freeze protection
When the evaporator temperature is too low this vital function prevents the evaporator to freeze by turning off the compressor to prevent liquid slugging the compressor, but keeping the indoor fan running continuously.

Automatic change over (heat pump models only)
When the outdoor coil temperature gets too cold the unit will automatically switch to electric heating and the compressor will shut off. The compressor will resume operation when the outdoor temperature raises enough.

Comfort quick warm-up (heat pump models only)
Once the room temperature falls 8º F below the set temperature, the compressor in the heat pump mode shuts off and the auxiliary electric strip heater is turned on for one cycle until heating set parameters are satisfied.

Last generation control panel
Control panel has LED indicators and push buttons for MODE, FAN, POWER and set points UP and DOWN. The control can display the temperature either in ºF or ºC.

High temperature safety protection
In heating mode the compressor and electric heater will be switched off once the indoor air supply temperature becomes too high to prevent any damage to the unit.

Easy to clean filter
Pull out long life polypropylene dust collector filter offers effective air filtration and is easy to clean and to maintain without opening the intake front panel.

Easy to use controls
KTHM control panel is designed for simple operation. Controls are easy to read, understand, and activate by the help of LED lights showing current status. This is ideal for commercial applications eliminating phone calls to floor managers. Customized set point temperature limits provide a restricted range of temperature control for commercial applications reducing power consumption of the building.
