Prevents the need to manually reset the WSHP. Keep in mind that whenever the furnace control board shuts unit down, gas shuts off immediately, inducer continues running for 15 sec, and if blower is running it remains running at low-heat speed or reduces to low-heat speed for selected off delay. We have a 15 year old Climatemaster Horizontal Ground Loop Geothermal system that is having problems. Low Pressure Switch Desuperheater Pump High Pressure Switch Hydronic Pump Relay . Then, subtract the high pressure from the low pressure to arrive at the Delta P. At this point, refer to the manufacturer’s specification book. Geothermal Heat Pump Has Lost Heat. After reseting, the flowmeter indicated flow between 9 and 11.5 gpm, which did not cause an faults! When the unit does operate without tripping the sensor it does not produce the kind of heat that it should. A split systems allows the owner to retro-fit when converting to a WSHP system. This scale can eventually cause the loops to develop clogging and high water pressure. System Pressure Trip - Discharge or vapor pressure out of limits or compressor overloaded: 1 Check high head pressure or discharge line sensor. Our system says system malfunction alert 83 / low pressure lockout 4hrs 3 events active. The pump should quiet down after repressurizing, *NOTE: Low loop pressure may be the result of pipe expansion do not immediately assume you have a leak in the loop! So the unit had a low pressure fault during stable 10 gpm flow. ... Low Pressure Switch: Protects the refrigerant system from low suction pressure, if suction pressure falls below setting. All coaxes are pressure rated to 450 psi water side and 600 psi on the refrigerant side. I have a 5 ton heat controller unit that is only about 3 years old. Although many geothermal heat pump problems have simple solutions, all require immediate attention to prevent any permanent damage.
