Trouble with relay

[ag22]

I've been learning a lot from these forums, thank you all.

I have a suntouch control panel controlling a pentair pump. In addition, an auxiliary relay controls a polaris booster pump. This relay was not working and was replaced yesterday by a technician. The polaris worked yesterday, however today it looks like the booster is not turning on again. Any tips for troubleshooting?

Is your booster pump still programmed to go on or is it just a manual turn on?

It is programmed. I also tried switching it on manually.
