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?
