Setting up PAB powerboat to P4

Hi,

I am trying to set up a PAB powerbar to my new Profilux P4. I have watched the video online which says the first PAB device was automatic assigned to S1 to S5. I have tried to set 2 heaters to be in S1 and S2. One is in the refugium and 1 is in the return section of the sump. I have set the temperature to 26.2C with a hysterisis of 0.3C. I have not yet connected the heaters as I wanted to get it all programmed before swapping it from the P2 I have currently on the tank. The S1 says off but S2 is saying on. Please can you advise me what to do to correct this?

If these two heaters are expected to react at the same time, you should have the S1 and S2 sockets set to the TEMPERATURE HEATER function. If you only have 1 temperature probe in your setup, make sure BOTH sockets are set to TEMP HEATER 1. This will allow both heater to react according to the values provided by Temperature probe #1.
