Electric water pump control

Evening,


Im trying to setup my electric water pump to work on timers rather than progressive pwm. Here’s the planned setup -


OUTPUT on when…..


ECT less than 50deg

Timer 1 True for 10 seconds Off for 30 seconds

OR


ECT more than or equal to 50,

ECT less than 70

Timer 2 - True for 10 seconds Off for 10 seconds

OR


ECT more than or equal to 70,

ECT less than 80

Timer 3 True for 5 seconds Off for 1 seconds

OR


ECT more than or equal to 80



ive set up the timers but can’t add all the variables onto the output channel. Could I do something with maths channels? each mode also needs to have “rpm more than 600” so it only works when engine is running.

cheers

If you use a Maths block to have ECT divided by a timer/1000 , as its in milli sec ( timer for 6 on 3 off) . Have the pump on while maths blocks value is more than 10. And on if ECT is over 65 deg. That will free up some space.
