I purchased a programmable thermostat and love the results. Only issue is that it controls only one zone. My goal is to control all three zones. I would like to have one "brain" that has three separate temperature sensors that control three separate circulator pumps. One for each zone. This way I can do the programming at the "Brain". I would like the three zones to be controlled independently. ie Zone one at 72 degrees and zone three at 68 at 4pm. I would also like to be able to control from my smart phone so I can warm the house up before I come home and monitor the temp while I'm away. I know in this day and age there has to be a better answer other than go buy three programmable thermostats and run all over the house to change schedules and settings. If there isnt then i have found my million dollar idea. I know it is possible. I could probably make it work with an aquarium controller but I figured there has to be a different option.
