The display lights up the AUTO symbol 6 2 2 Slope from 0_2 to 0_8 (low temperature) from 1_0 to 3_5 1_5 (high temperature) - see graph on page 42 If the external sensor is used, the boiler calculates the most suitable heating flow temperature taking the external temperature and the type of appliance into account. The type of curve must be chosen according to the type of appliance radiator and the heat losses present in the building. 6 2 3 Parallel curve shift Zone 2 Offset from - 7 to + 7 (low temperature) 0 from - 14 to + 14 (high temperature) To adapt the thermal curve to the appliance requirements, it is possible to perform a parallel shift of the curve in order to alter the calculated flow temperature and therefore the ambient temperature. By accessing this parameter or pressing the buttons 12 the curve can be shifted in a parallel manner as indicated in the figure shown below. The value is indicated on the display: - from -7 to +7 (low temperature) - from -14 to +14 (high temperature) Each step represents a flow temperature increase/decrease of 1°C in relation to the set-point value. 6 2 4 Compensation from 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. 6 2 5 Zone 3 heating MAXIMUM temperature from 35 to 85 °C 82 if parameter 620 = 1 setting from 20 to 45 °C 45 if parameter 620 = 0 6 2 6 Zone 3 heating MINIMUM temperature setting 6 3 DIAGNOSTICS 6 3 4 Zone 3 heat request 0 = OFF 1 = ON from 35 to 85 °C 35 if parameter 620 = 1 from 20 to 45 °C 25 if parameter 620 = 0 40 /
