Commissioning 4.2.3 Paral shift Press the selector . Turn the selector and set the most suitable value. Press the selector to confirm. 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 graph below, the curves have been divided into two groups: – Low-temperature systems – High temperature systems The two groups are divided according to the different point of origin of the curves, which for high-temperature systems is higher than 10°C, a correction usually made to the delivery temperature in these types of systems during climatic adjustment. 4.2.4 Room Influence Proportional Turn the selector and set the most suitable value, then press the selector to confirm. The influence of the room sensor can be adjusted to a value between 20 (maximum influence) and 0 (no influence). In this way, the contribution of the room temperature to the delivery temperature calculation can be adjusted. 4.2.5 Max T Turn the selector press the selector 4.2.6 Min T Turn the selector press the selector then set the most suitable value and to confirm. then set the most suitable value and to confirm. 4.2.7 Thermoregulation logic Turn the selector then set the most suitable value and press the selector to confirm.
