Turn on the power to the boiler and recommission the boiler to configure the connected motorised flue damper.
Note: If you are adding a Motorised Flue Damper to an Imax Xtra 2 that already has a Boiler Pump controlled directly from the
boiler you must observe the following:
• The On/Off Controlled Boiler Pump MUST be converted to Modulation Controlled Boiler Pump.
• If the Boiler pump has a PWM Modulation Input available you can use the schematic shown in Figure 3.
• If the Boiler pump only has a 0-10V Modulation Input available you need to order the 0-10V Pump Kit. The schematic
showing the wiring is shown in the instructions which are provided with the kit.
