1. Minimum outside design temperature:
Function 8
.
2. Design supply water temperature at the minimum design outside temperature:
Function 9
.
3. Maximum outside design temperature:
Function 10
.
4. Design supply water temperature at the maximum outside temperature:
Function
11

NOTE:
The homeowner can adjust the heat curve down by adjusting the central
heating temperature to a lower setting.
