The checking process for the suitability of the curve requires a<br />

long period of time during which several adjustments may be<br />

necessary.<br />

When the outdoor temperature rises (summer), three conditions<br />

may arise:<br />

– The room temperature increases, indicating that a gentler<br />

curve must be set.<br />

– The room temperature decreases, indicating that a<br />

steeper curve must be set.<br />

– The temperature of the room remains constant, indicating<br />

that the set curve is exactly right.<br />

Once you have found the curve which maintains the room<br />

temperature at a constant level, check the actual temperature<br />

value.<br />

IMPORTANT:<br />

If the room temperature is higher than the desired value,<br />

the curve must be shifted lower. If the room temperature<br />

is too low, the curve should be shifted upwards. If the<br />

temperature of the room corresponds with the desired<br />

value, the curve is correct.<br />

In the above graph, the curves have been divided into<br />

two groups:<br />

– Fan-coil systems<br />

– Underfloor systems<br />
