Commissioning The checking process for the suitability of the curve requires a long period of time during which several adjustments may be necessary.

Once you have found the curve which maintains the room temperature at a constant level, check the actual temperature value. IMPORTANT: If the room temperature is higher than the desired value, the curve must be shifted lower. If the room temperature is too low, the curve should be shifted upwards. If the temperature of the room corresponds with the desired value, the curve is correct. In the above graph, the curves have been divided into two groups: – Fan-coil systems – Underfloor systems 4.5.4 Offset Turn the selector then set the most suitable value and press the selector to confirm. 4.5.6 Max T Turn the selector press the selector then set the most suitable value and to confirm. °C 1 23 22 30 21 25 20 19 20 15 18 10 17 16 15 5 0 14 8 14 19 24 29 34 39 44 °C 2 Fig. 92 4.5.7 Min T Repeat the steps described previously to set the values for zone 2 (where present), by selecting the 5 Zone 2 parameters menu. 4.5.8 Delta T pump setpoint 4.7 ZONE REGULATION PARAMETERS 4.7.0 Heating Type Press the selector .
