Thermostat Differential

Goober

Seems that the new electronic thermostats out there sometimes have a "temperature differential" setting instead of the trusty anticipator.

What would bee the best setting for a residential steam boiler system with cast iron radiators? 1.5 degrees? That would provide a three degree temperature swing between cycles.

Any thoughts on this? Would the logest cycle be most efficent?

Differential

A 1.5 - 2* differential would be your best bet. But is it going to give you +/- 3-4*? Not sure. Might not over shoot that same amount--think other controls with differential settings...
Also, the LARGEST differential would NOT be the most efficient. Think average temp--you COULD maintain 70* by swinging between 60 & 80, but why would you want to? Godilocks had it right...

CYCLE RATE

Most good digital stats have an installers setup you need to go to and adjust the cycles per hour. This is what they use instead of a heat anticipator.
