Gold with Epsilon sky Update

The selection process for DX coil and related heat pump(s) has simplified

Main improvements are:

• There is now only one icon for dx coil
• Heat pump is assumed to always be present regardless of the supplier so the correct controls are set up.
• Epsilon Sky is set to default but can be altered to other supplier.
• A minimum of two heatpumps is recommended to give a better defrosting function and that is default.
• The heatpumps should be of the same size and the coil must be divided accordingly. The program supports that.
• Improved wiring diagram when Epsilon Sky is selected.
• Unnecessary selection menus have been removed.

 

Note that the lowest condensing temperature allowable in CH Design is 30 C
