5.1 Flow temperature

APPLICATION A230.1:
The ECL Comfort controller determines and controls the flow
temperature related to the outdoor temperature. This relationship
is called the heat curve.
The heat curve is set by means of 6 coordinate points. The desired
flow temperature is set at 6 pre-defined outdoor temperature
values.
The shown value for the heat curve is an average value (slope),
based on the actual settings.

Adjust the desired flow temperature at -30, -15, -5, 0, 5, and 15 °C,
if required.

Push the dial to enter / change the coordinates of the heat curve.
The heat curve represents the desired flow temperatures at
different outdoor temperature and at a desired room temperature
of 20 °C.
If the desired room temperature is changed, the desired flow
temperature also changes:
(Desired room T - 20) × HC × 2.5
where "HC" is the Heat Curve slope and "2.5" is a constant.
