Danfoss 077Z7 Installation guide

  • Hello! I've reviewed the provided Danfoss installation guide for the 077Z7 series thermostats. These thermostats have adjustable cut-in and cut-out temperatures and are designed for use with R290 and R600a refrigerants. The guide includes specifications for various models, including capillary lengths and minimum sensor requirements. I'm ready to answer your questions about these devices.
  • What refrigerants are these thermostats designed for?
    What is the operating range for these thermostats?
    Do all the thermostats have the same capillary length?

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
