Three system Waterfurnace geothermal 5 series package systems 2 alcohol ground loops pressurized with three flow centers, repressurized both to 65 PSI Inspected and reinstalled all existing air filters dated in January Clean and flush all drain systems and minor maintenance cleaning of all systems System B had 25 FP1 service codes But is running in excellent condition today. Suspect lower than desirable ground loop antifreeze pressure All equipment is running in very good condition and ready for summer
Upon arrival the system was in FP1 lockout and retry mode with 420 logged FP1 short cycles. Last visit to this house was Seth replacing the ABC board in November 2023. Hafter reset and retry I witnessed the system attempt to cycle on once and shut right back off within 2 to 3 seconds almost like a contractor chattering on and back off. After an additional retry with the system running the equipment appeared to be functioning properly with the FP1 sensor stable at 25 to 28° in low stage heat. After switching to high stage heat The system ran good for 30 seconds to 1 minute until it instantly dropped off to -3°f within two or three seconds and proceeded to lock out again on FP1. After investigating the control boards, wiring, sensors, and installing refrigerant gauges and water temperature sensors The system turned on and ran normal and exactly to book specs including refrigerant pressures, superheat and subcooling, water temperature drop and air temperature rise. All perfect to 30° wat

Three Waterfurnace 5 series all running in new condition. Individual air filter are in new conditon. Changed this month by Josh. Tested electric strip heat and tested watt usage on each unit. Blower motors are all operating within spec. Tested each unit in geothermal heating aswell. Through Aurora Aid Tool, checked electric strip heat Watt usage, blower motor amp draw, Heat of extraction, compressor Amp draw, and refrigerant pressures. No issues detected for any units while on site today. All systems are properly operating and ready for Winter.
Corinthian will be responsible for the bill due to the fact that the fans are in operating conditions from what I can tell. Shower fan will not come on by the switch. Shower switch actually turns the light and fan off to the toilet room. Concerns for bathroom fan being loud are believed to be caused by the fact that with the shower switch off the bathroom switch will not cycle the bathroom light or the fan unless you turn on the switch at the shower. They said it never made noise prior and now it seems louder than before but that’s because it only works with the shower switch on
Furnace had stored faults for ignition failure. Cleaned flame sensor, checked propane pressure. Adjusted house regulator and set furnace Manifold pressure to 11".
Dispatched for after hours no heat call. Found gas cock shut off. Open gas tested operation. Set Vision Pro 8000 to 2 deg droop and 4 hr Aux timer. Explained operation to customer. System operating correct at this time. Removed diag fee and consider this a one time free inspection after construction.
