Upon arrival customer said he has been getting FP2 faults since installation, mostly when it is very cold outside. Customer had another company come out and they found the water flow pipes were backwards and also that one of the 2 flow center pumps werenâ€™t wired to run. During diagnostics I found that the loop pipes were in fact backwards. In and out are reversed at flow center. Then I found variable speed pump running but fixed speed pump not, fixed speed pump wasnâ€™t wired to terminal block. Spoke to Alex and he approved repairing system under warranty. Swapped water flow lines at the unit. Had to shut off flow center and remove water. After switching I added the water I lost then purged the air from the outside while slowly opening the in side. Pushed all air out then pressurized again. Made sure all air was out of lines and pump. Wired fixed speed pump then checked for leaks, none found. Powered up system and ran heat.
