Easy maintenance and always clean. Troublesome maintenance has been made easy.

Since the front panel is easy to remove, maintenance is also easy.

MIN. HEAT Operation



The room temperature can be set to go no lower than 50°F, thus ensuring that the room does not get too cold when not occupied

Caution)

When the room temperature is higher than 50°F, “MIN. HEAT” operation does not star t. Operation starts and maintains the room temperature



• at 50°F when the temperature drops below 50°F.

Built-in timers



Select from four different timer programs (On / Off / Program / Sleep).

Program timer



The program timer operates the ON and OFF timer once within a 24 hour period.

ASU18-36RL

Sleep timer



The sleep timer function automatically corrects the temperature thermostat setting according to the time setting to prevent excessive cooling and heating while sleeping.

Cooling operation / dry operation

When the sleep timer is set, the set temperature automatically rises 2°F (1°C) every hour. The set temperature can rise up to a maximum of 4°F (2°C).

The air conditioner custom code is set to A prior to shipment.

The remote controller resets to custom code A when the batteries in the remote controller are replaced. If you use a custom code other than custom code A, reset the custom code after replacing the batteries. If you do not know the air conditioner custom code setting, try each of the custom codes ( you ﬁnd the code which operates the air conditioner.

STEP 2 Selecting the Function Number and Setting Value

Press the SET TEMP. (1. number. (Press the MODE button to switch between the left and right digits.)
