COMMISSIONING Gas

COMMISSIONING Gas Changeover The boiler is factory setted for the gas type indicated on the data plate. The adjustment, if necessary, must be performed by a Qualified Technician. It is not necessary a conversion kit, because the boiler has a auto adaptation gas system. Proceed as indicated: 1. Change parameter 202 to the new gas (see Technical Area). The display shows the error “The boiler must be calibrated”. 2. Perform the Calibration procedure and check the CO2 as indicated at the page 30. 3. At the end apply, near the data plate, the new label (supplied with the product) indicated the new gas type used. 4. Verify and repair any leaks of gas. WARNING!! THE AUTOMATIC CALIBRATION MUST BE DONE IN CASE OF: - REPLACEMENT OF: FAN, GAS VALVE, AIR/GAS MIXER, BURNER, ELECTRODE. - REPLACEMENT OF P.C.B. - GAS CHANGEOVER - ANY MODIFICATION TO THE FOLLOWING PARAMETERS 220 - SOFT IGNITION 231 - MAX CH ADJUSTABLE 232 - MAX DHW PERCENTAGE 233 - MIN PERCENTAGE 234 - MAX CH PERCENTAGE G20 20 mbar G230 20 mbar G30 - G31 28/37 mbar Example: Boiler adjusted for LPG 34 /

COMMISSIONING AUTO function This is a function which enables the boiler to automatically adapt its operation routine (the temperature of the heating elements) in line with the outdoor conditions, in order to achieve and maintain the requested room temperature conditions. Depending on the peripheral units connected and the number of zones controlled, the boiler adjusts its flow temperature automatically. The various corresponding parameters should therefore be set (see adjustments menu). To activate the function, press the AUTO button. 20/11/15 10:22 0° 40° 1,5 bar 70° AUTO C Heating active Example 1: Single zone system (high-temperature) with on/off room Thermostat: In this case the following parameters must be set: 4 21 - Activation of temperature adjustment using sensors - Select 1 = Basic temperature adjustment 2 44 - Boost Time (optional) The wait time for the flow temperature increase in steps of 4°C may be set. The value varies according to the type of system and installation. If the Boost Time value = 00 the function is not activated. Example 2: Single zone system (high-temperature) with on/off room Thermostat + outdoor sensor: In this case the following parameters must be set: 4 21 - Activation of temperature adjustment using sensors - Select 3 = outdoor sensor only 4 22 - Temperature adjustment curve selection - Select the relevant curve according to the type of system, installation, heat insulation used in the building, etc. 4 23 - Perform a parallel curve shift if necessary, increasing or decreasing the set-point temperature (this may also be modified by the user, using the heating temperature adjustment knob, which, with the Auto function activated, is used to shift the curve in a parallel manner). Example 3: Single zone system (high-temperature) with Sensys controller + outdoor sensor In this case the following parameters must be set: 4 21 - Activation of temperature adjustment using sensors - select 4 = outdoor sensor + room sensor 4 22 - Temperature adjustment curve selection - Select the relevant curve according to the type of system, installation, heat insulation used in the building, etc 4 23 - Perform a parallel curve shift if necessary, increasing or decreasing the set-point temperature. (This may also be changed by the user by the buttons 8 which, with the Auto function activated, is used to shift the curve in a parallel manner.) 4 24 - Influence of room sensor - used to adjust the influence the room temperature has on the calculation of the set-point flow temperature (20 = maximum, 0 = minimum).
