This may mean that the filters may need to be cleaned. According to service manual the unit has a "Serial reverse transfer
error at start up operation". Call fujitsu for service if the fault cannot be rectified.

SOURCE: TOYO TA-09CHS aircon problem
TOYO mini split air conditioner made in Japan is very very good quality and it can runs for 20 years without any problem. You didn't hire a best ac technician to install your TOYO unit. The tubing connection between indoor unit and outdoor unit is not the right torque and refrigerant leak. Your TOYO unit runs out of refrigerant. You need fix the leak and fully charge the system. You will solve the problem.

It's 98 outside ... that says a lot. The gurgling is an indication that you are getting a lot of water out of the air (dehumidifying). If the unit is sized just right, or just a little too small, it may be working perfectly well.
You don't say where you are, geographically, but much to the US has an air conditioning design temperature of 95 degrees F. That means at 95 degrees, the unit will run continuously. With a 50% outside air relative humidity, it should keep the occupied space at about 75 degrees F. The more humid the air, the more the unit works on dehumidifying and less on cooling.
Give it some time, wait unti the weather breaks and see if it doesn't run just like it used to. If you chose to call a technician, have him/her take temperature readings of the condenser entering and leaving air, the suction line temperature, the liquid line temperature, the inside supply and return air temperature (dry bulb and wet bulb) as well as high and low side refrigerant pressures. Before they make ANY changes to the system (refrigerant charge) have them explain what they found wrong and make sure you understand what they are talking about. Adjusting the charge under these conditions, will mess up your operation under normal conditions.

To cancel the timer, press timer on setting until it comes 00.00. Or remove batteries from remote and re fix after few minutes. If still problem persists, check and rectify error code of e-5 as follows:
Comms Error, check your wiring, remove external pumps. Split/Multi - check volts from terminal N to 3 = 0 - 65 Vdc, Multi V - 4 Vdc terminals 3 and 4
