His low operating costs are reflected in how much energy the geothermal systems save. 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. to 49°C]) found in geothermal systems. Water-to-Refrigerant Heat Exchanger Coil Large oversized coaxial refrigerant-to-water heat exchangers provide unparalleled efficiency. my waterfurnace unit shutsown on low pressure. 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, … 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. I have another update. ... Geothermal heat pumps work toward the preservation of … Either there isn’t enough water fl ow or the entering water temperature is improperly Troubleshooting Guide - Tranquility® Digital (DXM2) Packaged Units Rev. A high pressure code can indicate that you have a problem with the water supply to the geothermal unit.

The coaxes are designed for low pressure drop and low flow rates. 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. Water to Refrigerant Coaxial Heat Exchanger Coil Large oversized coaxial refrigerant to water heat ex-changers provide unparalleled efficiency. There isn't much point in having a heat pump which doesn't produce heat, and this is a problem that you need to deal with right away. In cool mode with outdoor temp 72F low side around 125 PSI and High side about 280PSI.
