I need a complete plan on how to build an adjustable timer controller with a temperature controll and overide to set up to controll a hydroponic system. basicly 15 mins on 15mins off with a overide one the tem hits 30dcelsius

hi,

i presume that you want the override to function during the off period of the timer. connect the output of the temp.sensor to the trigger of the timer. but make sure that the trigger voltage coming from the temp. sensor is the same as the timer circuit.
