Danfoss 077Z7 Installation guide

  • I've reviewed the installation guide for Danfoss service thermostats 077Z7010, 077Z7011, 077Z7012, and 077Z7013. The guide provides information on installation, settings, and safety for these thermostats. I can answer questions about their features, compatibility with R290 and R600a refrigerants, and their cut-in/cut-out temperatures.
  • What is the working fluid compatibility of these thermostats?
    What is the recommended action for new systems in countries with no conformity certification?

The 077Z….EBD, 077Z….L EBD can be applied on systems with R290 and R600a as the working fluid.
Always adhere to local codes and safety guidelines. For countries with no conformity certification (UL, CE, CCC, CSA, EAC, etc.)
requirements on new systems, Danfoss recommends third party apporval for systems containing flammable refrigerants.
Note: All temperatures at 760 mm Hg
