Central Heating Curve Function
Central heating demand is detected when the room thermostat closes. When an outside sensor is also connected, the supply
temperature will depend on the factory default central heating curve.
To set your heat curve, you will have to set the following parameters:
1. Minimum outside design temperature:
Function 8 .
Table 15
– Central Heating Curve – Factory Default
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: Versa-Flame minimum set point Function 49 may override the supply temperature for Function 11.
NOTE: The homeowner can adjust the heat curve down by adjusting the central heating and/or DHW temperature to a lower setting.
