Philip Pugh Posted June 8, 2004 Report Share Posted June 8, 2004 We all know that you can test a heatpump in the cooling mode if our temp is 65 degrees or higher for the last 12 or so hours. When our temperature is around 72 degrees plus is it protocal or even wise to also run the unit in the heat mode ? Quote Link to comment Share on other sites More sharing options...
Scottpat Posted June 8, 2004 Report Share Posted June 8, 2004 In the heat mode (not the emergency heat mode) the pressure will build up in the system if it is warm outside. So yes you can damage a HP in warm weather. Some will not even cut on if they have an outside temperature sensor and it is too warm outside.

Paul MacLean Posted June 9, 2004 Report Share Posted June 9, 2004 I only run heat pumps on one mode (heating or cooling) depending on the season and outdoor temperature. But I always test the emergency heat feature regardless of the outside temperature. Quote Link to comment Share on other sites More sharing options...
Konrad Posted June 29, 2004 Report Share Posted June 29, 2004 By no means am I a heat pump expert, but shouldn't every heat pump have a high head-pressure over-ride shut off, to prevent damage as described above? We don't have a lot of them here, I wish I were more versed with heat pump theory. [:-indifferent] Quote Link to comment Share on other sites More sharing options...
