- Page 14 Pioneer Brand, WYD Series 13 SEER Ductless Split System Heat Pump Engineering and Service Manual Note: Please read the entire installation manual packed with the unit carefully and follow all instructions, during and after the installation. Your system has been fully tested and ran properly for a sufficient amount of time at the assembly line before it was approved and packed for shipment. All functions and components were verified to be in perfect working condition. Therefore a majority of problems and deficiencies are usually due to causes other than a factory defect. See below for some common problems, reasons and solutions. Call us for any other issues that cannot be resolved for further assistance by our engineering support. We can only help, if you are able to describe the symptoms properly and able to measure and advise us certain measurements such as voltages, temperatures and pressures on the system. Symptom : E1 Error display on the indoor unit. Reason : Indoor Unit's Room Temperature Sensor Open or Shorted Circuit. Solution : Check for resistance. If measuring as open or shorted, replace the indoor unit's room ...
- Page 15 Symptom : In HEAT Mode, indoor unit is blowing cold air instead of heating. Reason : Missing wire connection, defective reversing valve actuator. Solution : Otherwise, assure that the YELLOW wire is attached to terminal #3 on the outdoor unit. Also check that the same yellow wire is either connected to the #3 terminal on the indoor unit (009, 012, 018 models) or the white plug at the end of the cable at the indoor side is plugged with the matching white plug on the indoor unit properly (for 024 models only). While in Heat Mode: Check for voltage between #3 and N terminals on 115V models and assure it reads 115V or check between #3 and L2 terminals on 230V models and ...
- Page 16 Symptom : Water dripping from the indoor unit. Reason : Misaligned installation leveling, blocked drain tube, frozen coil. Solution : Check that the indoor unit is installed in a perfectly horizontal position. Check that the end of the drain hose is dripping water properly on the outside. Check that the drain tubes are not kinked, blocked or siphoned. Assure that the drain hose stays as low as possible in the wall hole and has a continual proper declination in its level. Check the evaporator coil if frozen. This can be the indication of refrigerant loss from the system. Check and assure correct operating pressures. Check for kinks in copper lines. Always close all open windows and doors to avoid excessive humidity entering the room. ...
- Page 17 Symptom : System does not automatically restart after a power failure. Reason : Auto Restart Function has been turned OFF. Solution : Turn OFF the breaker, Press and hold the emergency restart button and turn the breaker ON while still holding the button pressed for 10 more seconds. 5 beeps indicate activation of the Auto Restart function.

Solution : Clean the filters. If the coil is dirty have the evaporator professionally cleaned. Run the unit for several hours in FAN ONLY mode to dry it before preparing to leave the system OFF for long periods of time. Symptom : Uncomfortably wide temperature swings in the room. Reason : Indoor unit installed too high, filters dirty, Room temperature sensor deficiency. Solution : Higher locations in the room will have warmer temperatures and the system will measure the temperature at the height the indoor unit is installed. User can compensate for this by setting the temperature ...
