    Confused ceiling mounted climatemaster geothermal heat pump, i need help

    i got a government building that has just recently installed 47 ceiling mounted geothermal heat pumps. they are all climatemasters. i am having a problem with a handful of units that are going into a lockout alarm. pressures are good, they run for a period of time (some run a few hrs and some run for a couple days) and when they lockout the fan continues to run. condensate is clear, freeze protection checks out. i am about to change out the control board on 1 unit. anyone got any experience with these climatemasters, have you had this problem and what you did to fix it?

    Model numbers would be nice information to have. What code is it giving you?

    Sounds like water flow problem. Have you checked screens on these units?

    Always seems like there is dirt in lines no matter how much flushing is done.

    Dirt,dirt,dirt......in other words water flow. Also water temperature. Check that beafore you start replacing control boards.
