Page 6: Features And Functions
SMA/SMH OWNER’S MANUAL Heat Controller, Inc. Features and Functions: Low Ambient Operation and Crank Case Heater Feature: When cooling is needed year round, including when outdoor temperatures are apt to fall below freezing, our S Series ductless mini-split systems will continue to work, as they come with factory installed low ambient con- trols. The low ambient feature works by regulating the head pressure by varying the amount of air flow through the condenser, which helps to prevent evaporator freeze ups and low pressure problems due to low ambient outdoor temperatures. Low ambient operation is a great feature for temperature/humidity sensitive environ- ments or applications such as server/computer rooms, supermarkets, restaurants, or cooling tower fans. Additionally, a crank case heater is required and factory installed, as it is needed for use with the low ambient controls. The crank case heater minimizes liquid refrigerant migration to the compressor when the compressor is not operating and helps to keep the compressor oil warm enough so that it remains fluid to prevent slugging. Crank case heaters also assist to greatly reduce heat loss to ambient air. Together, the lower ambient feature combined with the factory installed crank case heater, will not only allow the air conditioner to cool year round, but will also prevent compressor failure in low ambient conditions. See chart below for operating conditions: Ambient Operating Conditions Mode Temp... - Page 7 Heat Controller, Inc. OWNER’S MANUAL SMA/SMH AUTO operation • When you set the air conditioner to AUTO mode, it will auto- matically select cooling, heating (heat pump models only), or fan only operation depending on what temperature you have selected and the actual room temperature. • The air conditioner will control room temperature automatically around the temperature set point you select. • If the AUTO mode is uncomfortable, you can change desired temperature settings manually. ECONOMY/SLEEP operation When you push ECONOMY button on remote controller it activates SLEEP mode. During cooling, heating (heat pump only), or AUTO operation, the air conditioner will automatically increase (cooling) or decrease (heating) 2°F (1°C) per hour. The set temperature will become steady 2 hours later. The SLEEP mode will turn off after 7 hours and resort back to the previous settings. The fan speed will be automatically controlled. This feature can maintain the most comfortable temperature while you sleep and save more energy during use.

Page 8: Airflow Direction Control
SMA/SMH OWNER’S MANUAL Heat Controller, Inc. Airflow Direction Control NOTES: • Use the remote controller to adjust the horizontal louver • Manually adjust the vertical louver. To set the vertical air flow(Up–Down) direction Perform this function while the unit is in operation. Use the SWING button on the remote controller to adjust the air flow direction. The vertical louver can be moved at a range of 6° for each press of the swing button, and if Vertical louver pressing more than 2 seconds, the automatic swing func- tion will be activated and the louvers will move up and down automatically to create a breeze-like effect. Please refer to the REMOTE CONTROLLER OPERATION MANUAL for details. To set the horizontal air flow direction (left–right) • Move the left to right louver manually to adjust the air flow in the direction you prefer. -
Page 9: Typical Operational Occurrences
Heat Controller, Inc. OWNER’S MANUAL SMA/SMH Typical Operational Occurrences The following events may occur during normal operation. 1. Protection of the air conditioner. Compressor protection • If the unit is stopped and then immediately restarted again, the compressor will not operate for about 3 minutes in order to protect the compressor. Anti-cold air (heat pump models only) • The unit is designed not to blow cold air in HEAT mode, when the indoor heat exchanger is in one of the following three situations and the set temperature has not been reached. A) When heating has just starting. B) Defrosting is occurring C) Low temperature heating is occurring Defrosting (Cooling and heating models only) • The indoor or outdoor fan stop running when defrosting (heat pump models only). - Page 10 SMA/SMH OWNER’S MANUAL Heat Controller, Inc. 7. Condensation • Dripping water may generate on the surface of the indoor unit when cooling in relatively high humidity. Adjust the vertical louver to the maximum air outlet position and select HIGH fan speed. NOTE: Water could drop onto the floor or objects below the indoor unit. 8. Heating mode (heat pump models only) • The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heat- ing operation. When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time, the heat load of the air conditioner increases due to larger difference between indoor and outdoor temperature. If a comfortable temperature can’t be achieved by the air conditioner, we suggest you use a supplementary heating device. 9. Auto-restart function • Power failure during operation will stop the unit completely. • For units with the Auto-restart feature, when the power restores, the unit restarts automatically using the previous settings preserved by the memory function of the unit. Timer settings may need to be adjusted after a power failure. 10. Electrical interference • Electronic equipment which uses wireless radio transmitters within 3 ft (1m) of the air conditioning unit may cause the unit to malfunction. Disconnect the unit with power and then re-connect the unit with power again. Push the ON/OFF button on the remote controller to restart operation. Ensure that the air conditioner unit is as far away from any electronic interference sources as possible, otherwise wireless interference can occur.

Heat Controller, Inc. OWNER’S MANUAL SMA/SMH Care and Maintenance Cleaning the Grille, Case and Remote Controller • Turn the system off before cleaning. To clean, wipe with a soft, dry cloth. Do not use bleach or abrasives. NOTE: Supply power must be disconnected before cleaning the indoor unit. CAUTION! • Do not use an overly wet cloth to clean the unit as it may damage the electronic components. A damp cloth can be used if needed. - Page 12 SMA/SMH OWNER’S MANUAL Heat Controller, Inc. 4. Remove the air freshening filter (optional on some models) from its support frame • Clean the air freshening filter at least once a month with a vacuum clearner, and replace it every 4-5 months. 5. Install the air freshening filter back into position. 6. Insert the upper portion of air filter back into the unit taking care that the left and right edges line up correctly while placing the filter into its original position. CAUTION! • Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges. • Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation or electrical components, leading to possible electric shock. • When cleaning the unit, first make sure that the power and circuit breaker are turned off. Maintenance: If you do not plan to use the unit for an extended period of time, perform the following: (1) Operate the fan for about half a day to dry the inside of the unit. (2) Stop the air conditioner and disconnect power. Re- move the batteries from the remote controller. (3) The outdoor unit requires periodic maintenance and cleaning. Do not attempt to do this yourself. Contact an authorized service. Check before operation (after extended period of non-use): • Check that the wiring is not broken off or disconnected.
