The old pool heating controller was getting old and was needing to be replaced. This controller is the same as the old one with hopes that it will be soon upgraded to a better program.

After finding out that a new controller for the solar heating will cost $500, i got to work building my own. As it is going into winer, the controller will go into 'winter' mode. This simply means that the controller will turn on the pump once a day for about 5mins. This helps to stop the damage being done while its not being used.
The old controller is using 2 sensors (one on a pipe close to the pool and one on the roof) to see if the solar can heat up the pool. I'm hopping the the sensors are in good condition so that I can use them for my controller. My controller will similar to the old controller but with better readouts and more control over the pump.
