DIGITAL Geothermal Heat Pumps TE/TZ/TES/TEP 97B0601N01 Rev. I changed the unit to cooling mode and ran it for around 10 minutes with no problems and then switched it back to heating mode and I did not have a low pressure lockout. His low operating costs are reflected in how much energy the geothermal systems save. 2 Different Techs have been 3 times but can't isolate the problem. does this indicate i need a new board or does this happen if it is really low pressure meaning a need a charge. Compressor A, which is Stage 1, keeps locking out with a High Pressure Fault. ft. building 4 years ago. When the unit does operate without tripping the sensor it does not produce the kind of heat that it should. After reseting, the flowmeter indicated flow between 9 and 11.5 gpm, which did not cause an faults! However, this drops the temperature drastically . So the unit had a low pressure fault during stable 10 gpm flow. You should watch for any codes that indicate high pressure switches or FP sensors. Refrig-erant and coaxial heat to 49°C]) found in geothermal systems. "When the Comfort Alert senses a fault that the Premier2 board will act upon (lockout), the Envision Low Press/Comp LED will flash. At this low pressure and room temperature, the Freon will evaporate and become a gas. The coaxes are designed for low pressure drop and low flow rates. High-pressure control open/Low-pressure control open; Miswiring of communications; REMEDY: Check for correct voltage at line voltage connections in condensing unit. If the pump is making noise, this is another sign of low pressure or air in the system. I have a 5 ton heat controller unit that is only about 3 years old. System Pressure Trip - Discharge or vapor pressure out of limits or compressor overloaded: 1 Check high head pressure or discharge line sensor. geothermal systems. Miami Heat Pump offers a superior quality water source heating and air conditioning system. The geothermal ground loop needs to be reflushed if air is present. Designs for all applications, residential and commercial. (Check fault code) • If compressor is operational, Verify that the voltage and amperage drawn is within designed parameters. Reset. Replace fuses/reset breaker. Though lockout mode errors and resets do vary from manufacturer to manufacturer, most use a simple reset procedure that involves turning power off to the furnace for thirty seconds or longer and turning it back. After completing the checklist, if your geothermal system is still not working properly, call Scott-Lee Heating Company at (314) 200 … Also an update on low pressure lockout condition: Tech came out and after checking subcool with gauges determined everything seemed fine. Failure to heat is probably the first sign that something is wrong, but a complete lack of heat suggests a couple of simple reasons that you can fix in a few minutes. Most problems relate to water fl ow. A FP sensor code can indicate that your system is low on charge, or you may have a bad FP sensor (there are 2). In cool mode with outdoor temp 72F low side around 125 PSI and High side about 280PSI. : 3/10/15 Tranquility ® Digital (DXM2) Troubleshooting Guide Table of Contents Introduction 2 Troubleshooting Flow Chart 3-9 Flow Chart Reference Symbols and Diagrams 10 Contactor Chart 12 Verifying Pump Feedback Signal 12 Removing Powerhead on Modulating Valve 13-14 … • FOUR BLINKS 2nd Stage low pressure lockout • FIVE BLINKS Freeze Protection lockout •SIX BLINKS Condensate overflow lockout • INTELLIGENT RESET - If a fault condition is initiated the 5 minute delay on break time period is initiated and the unit will restart after this delay expires. Our system says system malfunction alert 83 / low pressure lockout 4hrs 3 events active. For low pressure, a technician can repressurize your system and check for leaks that may have caused the drop in pressure. Geothermal Heat Pump Has Lost Heat. Also see high head pressure remedy. The cold winter climate has driven the design of Check wiring. in normal display mode the green status light blinks. Flow Proving Switch (Differential Pressure) shuts down the WSHP before unit can go into hard lockout faults due to water flow issues (ie. This lockout condition means that the unit on the electrical box cover panel of the GeoSource 2000 has shut itself down on a low or high-pressure switch to heat pump. A high pressure code can indicate that you have a problem with the water supply to the geothermal unit. The general alarm is initiated when the control goes into a manual lockout mode for either high pressure or low pressure. If the pressure is sufficient, make sure the loop pumps are operating. To determine which caused the lockout, simply look at the CA and determine if it flashing one of the lockout conditions 2, 4, 6, 7." ft. home that we designed the geo- thermal system in 2003, and their offices in the 9,000 sq. — High & low pressure switches — Lockout circuit — Unit protection module (UPM) standard in -CSC,-CSN models — Unit mounted controller (UMC) standard on -USC,-USN models Standard Warranty — 10 Year All Parts Limited Warranty — 10 Year Labor Limited Warranty Replace transformer. Plus the non pressurized flow centers are usually placed before the circulator pump and the heat pump, thus any air in the loop would have been purged out before it hits the pump and the heat pump, … So the blower starts but nothing else. 4 Return air duct has substantial leakage.

Low pressure fault in memory Flashing Code 3 ----- Cycling Code 3 Low temp ... • Check and correct any lockout condition present. In terms of residential flow centers, the geothermal heat pump industry is divided into two camps: pressurized and non-pressurized. At this point the tube containing the Freon moves through the region you want to cool, e.g. After the heat pump has run for five or 10 minutes, check the water pressure by inserting a water pressure gauge into the PT port and recording the water pressure in and the water pressure out. A split systems allows the owner to retro-fit when converting to a WSHP system. Stan and Chris DiStefano – highway construction general contractor. An internal 24-volt, 55 VA transformer is protect itself, and will not come back on until power has provided to operate all control features of the heat pump. If I power down at the breaker box, upon restart (after lockout time) it does it again the moment the startup signal arrives. I have another update.
