Actually you can use any thermostat, any dry closure relay contact would do, or even a simply 6 volt 250 ma power supply.
But programmable digital thermostats are really the way to go !
Thanks for the Post George:
It was my intention to design something very simple that works without interrupting the motors,( thus, extending the life of motors ) and to take advantage of the newer technology of off-the-shelf thermostats and provide the benefits of convenience and cost saving to coal stokers users. All at an affordable price for the average consumer.
Surprinsingly, the test results exceeded my expectations, thanks to newer developments in digital thermostat technologies using newer algorithms
Below are two pictures of a CoalPilot unit for the Leisure Line lines of stoves during off position, and on position , with a detailed operation of its working.
During an Off cycle, as crank arm C rotates, Bearing B approaches plate A which is welded to pin P .
Guide hole G along with the two bolts shown, ensure smooth movement of plate A and pin P pushes the small tab T against the carpert/slider causing it to move by a distance D.
During on On cycle, Solenoid S is energized through electrical connector E forcing arm K to engage itself in front of tab T and thus changing the travel distance D to be an increment of 1/4 inch or so ensuring a bigger load.
A metallic spring M brings back plate A, for a fresh operation every cycle.
CoalPilot units for other models operate on the same principle. The Coalpilot is in a Patent Pending status, A Patent is about to be issued !
Any Questions ?
