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
