the operating temp is 180.
A technical point - a high limit has a shutoff safety setting, it isn't an operating setting, The operating temperature is whatever the water temperature gets to according to the need. There is no need for the water temperature to operate at 180F all the time.

we have a high fire control that I have switched to only run when outside temp is less than 20. What should that temp be set at for optimum economy? It would be the inlet water temp that causes high fire to come on. Currently is set at 160. Thanks

The outdoor temperature switch setting would be most economical when kept at a temperature limiting the water to be just enough to keep all zones warm; but not allow the water temperature to be low enough to have uncomfortable temperatures when it is cold out.

There is no magic single setting for all houses; you will find that temperature setting by experience. If you find zones getting cold when set at 20F, then raise the temperature setting until warm.

If all zones are comfortable, try lowering the temperature until they start feeling cold, then raise it again over the day until all are warm. That would be the set temperature for the outdoor sensor.

The water temperature never needs to be higher than that needed for comfort at any outdoor temperature. That provides the most economy.
