    Intermatic T40004RT3 Timing Control Center

    Hi!

    I have an Intermatic T40004RT3 Timing Control Center. The unit has a Transformer built in for the low voltage lights, but the wiring from the breakers comes into the transformer and then goes out to an external Safety Volt ST-100 unit and then on to the lights.

    Is this a normal setup?
    Why 2 Transformers? Maybe redundancy?

    I'm installing an Aqua Plus from Hayward and need to know if the Transformer inside the Intermatic is required.

    Please help!

    Thanks!

    The answer:

    The Transformer inside the Intermatic Unit is a 300w Transformer for the Main Pool Light and the Smaller Safety Volt Transformer is for the Spa Light (100w)
