Press the selector to confirm. 4.1.1 Automatic winter mode threshold Turn the selector and set the auto summer/winter switching delay. 4.2.2 Slope Press the selector . Turn the selector and set the curve in accordance with the type of heating system. Press the selector to confirm. Low-temperature system (underfloor panels) curve between 0.2 and 0.8. High-temperature system (radiators) curve between 1.0 and 3.5. The checking process for the suitability of the curve requires a long period of time during which several adjustments may be necessary. When the outdoor temperature falls (winter) three conditions may arise: – The temperature of the room may fall, indicating that a steeper curve should be set. – The temperature of the room may rise, indicating that a gentler curve should be set. – The temperature of the room remains constant, indicating that the set curve is exactly right. Once you have found the curve which maintains the room temperature at a constant level, check the actual temperature value. °C 100 1 90 80 70 60 50 40 30 3.5 3.0 2.5 2.0 1.5 1.2 1.0 0.8 0.6 0.4 0.2 5 4 4.1.2 Automatic winter mode delay time Turn the selector and set the auto summer/winter switching delay. 4.2 SETUP 4.2.0 Zone temperature range Press the selector .

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.

Turn the selector and select: 0 Standard. 1 RT Time Programs Exclusion (In this mode, the heat requests generated by the RT remain active also during the night-time period in programmed mode). 2 Forcing Heat Demand (The activation of this function generates a constantly active heat request). Repeat the steps described previously to set the values for zone 2 (where present), by selecting the 5 Zone 2 parameters menu. NOTE: For correct operation of the temperature adjustment types: 2. Room sensor only: 3. Outdoor sensor only: 4. Room sensor plus external sensor, parameter 1.0.6 Thermoregulation should be set to value 1, or the AUTO function must be activated. 4.3 DIAGNOSTICS 4.3.0 Room T 4.3.1 Room T setpoint 4.3.2 Flow temperature 4.3.3 Return temperature 4.3.4 Heat Request Z1 Press the selector .
