Pc4 channel blinking

    I have my pv4 setup this way:
    Channel 1: 200 watt heater
    Channel 2: refugium led
    Channel 3: 2x150 watt metal halides
    Channel 4: ato
    When the halides and led shut off at 8 tonight the pc4 started blinking on channel three. Halides still work on a seperate strip, have not tested them yet on the pc4 I've tried to make sense of the manual and looked it up on google with limited success.
    Any ideas? Thanks!

    I would switch 3 and 4. channels 1 and 4 are 8A while 2&3 are only 3A.

    If you used the mH function it blinks for 15 minutes after power is out to protect the lamps. Though you should also swap 3 and 4

    It's it in the halide function, just never saw it blinking before. Should have figured it out. Will switch them but was afraid the ato would get stuck on as
    It does that sometimes to the powerheads on those channels.

    I would try to get either a second PC4, or a different pump for the ato. Other options might me a separate timer for the mh ( would loose the protection of the defer ability of the rk ) or a separate heater controller.

    Either a bad pc4 or a bad cord try switching cords around other thing to try is gently clean tge cord contacts

    I'd bet it's the connection via cable from the head unit to the pc4. They are prone to corrosion and the cables don't always fit securely. I would look at all your connectors and make sure they don't have anything inhibiting the contacts, wiggle the cables around a bit make sure they're making a solid connection. If you find corrosion, give the cable ends a vinegar bath and scrub with a toothbrush. I've had to do it several times
