The type of curve must be chosen according to the type of appliance radiator and the heat losses present in the building. °C temperatura di mandata all’impianto Flow Temperature 100 90 80 70 60 50 40 Ambient temperature setting value 30 25 20 15 valore di consegna temperatura ambiente °C 10 default etting 1 select in the appliance type base 1 To activate heating control, press the AUTO button.

The shift value between - 20 and + 20 is shown on the display. Each level corresponds to a 1°C increase in the flow temperature in relation to the initial setting. 4 2 4 Compensation 0 to + 20 20 if setting = 0, the temperature taken from the ambient sensor does not affect the calculation of the setting. If setting = 20, the temperature taken has maximum influence on the setting. 4 2 5 Zone 1 heating maximum 35 to + 82°C 82 if parameter 420 = 1 temperature setting 20 to + 45°C 45 if parameter 420 = 0 4 2 6 Zone 1 heating minimum 35 to + 82°C 35 if parameter 420 = 1 temperature setting 20 to + 45°C 20 if parameter 420 = 0 4 3 DIAGNOSTICS display only 4 3 0 Zone 1 room temperature Activated only with the modulating 4 3 1 Zone 1 set temperature device connected (option) 4 3 2 Zone 1 heat request 0=OFF 1=ON 4 3 3 NOT PRESENT 4 4 ZONE DEVICE MANAGEMENT 4 4 0 NOT PRESENT High temperature bassa tempertaura alta tempertaura low temperature 45
