Does the right hand know what the left hand is doing?

Imagine driving your car down the road with your eyes closed and the pedal to the floor board waiting for your passenger to yell stop.  That is what happens when your boiler sits in the basement waiting for the zone control to tell it to go, stop, go and so on.  The boiler doesn't know if it is connected to one zone or to twenty, it just assumes that if I am told to go I must need all my BTU’s right now.

What if we could have the thermostats talk to each other and the boiler control with just two wires, and they could set the water temperatures and control the firing rate of the boiler.  Well the Tekmar House Control and communicating thermostats can do just that and so much more.
