can be upgraded using a UCM05 Universal Communications Module (firmware 5.147 and above) and the Comfigurator software version 2.2.2 and above. It is recommended that UCM firmware 5.156 and above be used for firmware download as it does not require a prior login.
Switch off Comfort and disconnect the battery. Take care that self actuated sirens are silenced before attempting this
When using UCM 5.147 to 5.155, remove the MPU01 module from the Comfort PCB carefully using a flat edge screwdriver or rool to prise each edge from its connector, taking care not to bend the pins. For UCM 5.156 and above, the MPU01 can be left plugged into the Comfort PCB.
Connect the UCM05 to the MPU01 using the UCM05 programming cable
Connect the programming cable (with single 6 cables end) to PP1 on the MPU01
Connect the other ends of the UCM programming cable to the UCM05 that is used for programming to PP1 (with 4 cables end) and PP3 (for 2 cables end).
Switch on the Comfort system. Do not connect the battery. This assumes that the Comfort PCB without the MPU01 has a U1 with older firmware
