Shedule and trigger question

All,

I’m building with a RPi V3 a swimpool steering for pumps, heating, UV, pHreading, power monitoring, …

My question:
Can a relay be trigger by a temp high value when the shedule for the relay is in the off state.

what I mean is when the relay is off by the shedule and the temp of my solar heating is higher than a certain trigger point it will startup the pump to circulate the water and start heating the swimming pool or will the shedule still keep the relay of the pump in the off state.

Regards,

Yves

schedule and trigger are independent of each other. the scheduler only occur when the set time is reached, while the trigger occur when the desired set point is reached.
