I have a Mammoth Model DO35VSA1T Geothermal heat pump (water to air) in my house. When I initially ask it to heat it will kick on and the compressor comes on for a bit and then kicks off. It will continue to blow 95 to 100 degree air out of the vents. Heats the house up fine but when it goes off and then comes back on to reheat it just blows cold air until I turn it off and back on then it will heat. Any ideas. I have googled this and cannot find no info on this. Thanks in advance. I have no books on this unit, previous owner never had any either.
