Remote Control Operation

Remote Control – Refer to Figures 11 and 12 during operation description.

Getting Started – Install two (2) AAA batteries in the battery compartment located on the back of the unit.

Operation – The remote control should be within 25 feet of the air conditioner for operation (Refer to Figure 10 for effectiveness). Press the button to turn the remote on. The remote will automatically power off after 15 seconds if the buttons are not being pressed. The remote must

be on to control the unit.

POWER Button – Turns remote and unit on and off.

SYSTEM Button – Allows the user to sequentially select, Cool , HEAT, and FAN ONLY operation. When the button is pressed, the display indicates which mode has been selected via a display message. Note that when the heating function is not available, the system will automatically skip the HEAT and AUTO modes.

FAN MODE Button – Selects between automatic () or

operation. In the AUTO mode, the fan only turns on and off when the compressor operates or the heat function is enabled.

NOTE: AUTO is not available in the FAN ONLY Mode, the display

indicates . In the mode, fan speed is

determined by your selection on the button.

FAN SPEED Button – Used to sequentially select new fan speed, plus AUTO operation. When the SPEEDFA N button is pressed, the fan speed is temporarily displayed in the display window, plus a fan speed icon (triangle) changes to indicate the new speed level. Fan speed automatically varies depending on the set temperature on the control panel and the actual room temperature. Let me explain. Say for example you’re working in your garage and you need to open the big door for several minutes. Since there is a big difference between your set temperature and the actual room temperature the system fan speed increases to MAX. It remains at this speed until the room temperature matches the set temperature.

SCHEDULE Button – The SCHEDULE button turns the schedule function on and off. Pressing the SCHEDULE button a second time turns the schedule function off. Only the schedule icon will be displayed.

UP and DOWN Arrows – Pressing either the (UP) or (DOWN) button changes the desired room temperature. The factory preset lower and upper limits are 60° F (16° C) and 99° F (37° C). These buttons are also used to navigate between function options when using the User Menu or Maintenance Mode.

Remote Effectiveness

Hand Held Remote – Has an operating range of up to 25 ft. The infrared remote control signal must have a clear path to transmit the command to the air conditioning unit. The remote signal has some ability to "bounce" off of walls and furniture similar to a television remote control. The diagram below shows the typical operating range of the control in a standard room with 8 ft high ceilings.

Changing Temperature from F˚ (Fahrenheit) To C˚ (Celsius) or Reverse

Be within 25' of unit with the remote control. Press the SYSTEM and FAN MODE buttons at the same time and hold for 3 seconds. The display will show the temperature in Celcius. Do the same to reverse temperature to F˚ (Fahrenheit).

R-410A specifications

Friedrich R-410A is an advanced refrigerant widely used in HVAC (Heating, Ventilation, and Air Conditioning) systems, known for its high efficiency and environmental friendliness. As a hydrofluorocarbon (HFC) blend, R-410A has become the preferred alternative to R-22, which is being phased out due to its ozone-depleting potential. One of the main features of R-410A is its high latent heat of vaporization, which allows for efficient heat transfer and improved cooling performance in air conditioning units.

Technologically, R-410A operates at higher pressures than older refrigerants, meaning systems designed for R-410A need to be built with more robust components to safely handle these pressures. This results in a more compact system design that offers enhanced performance and reliability. The dual-component nature of R-410A—composed of difluoromethane (R-32) and pentafluoroethane (R-125)—provides an optimal balance of thermodynamic properties, leading to superior energy efficiency, especially in variable speed applications.

In terms of characteristics, R-410A has a higher cooling capacity, which enables HVAC systems to effectively cool larger spaces or run more efficiently when cooling smaller areas. The refrigerant is non-toxic and non-flammable, which enhances safety during its use. In addition, R-410A has a lower global warming potential relative to other refrigerants, making it a more environmentally responsible choice for modern cooling systems.

Moreover, R-410A systems typically require less refrigerant charge due to their efficiency, contributing to reduced greenhouse gas emissions. The adoption of R-410A aligns with regulatory trends aimed at minimizing the environmental impact of refrigerants in cooling applications.

Overall, the Friedrich R-410A refrigerant embodies a combination of technology and environmental stewardship, making it a cornerstone of contemporary HVAC design. Its ability to provide effective and energy-efficient cooling solutions while being compliant with modern environmental regulations positions R-410A as the refrigerant of choice for engineers and installers focused on sustainability and performance in air conditioning systems.
