Danfoss ret-b thermostat

[jjpearce05]

I have a danfoss ret-b thermostat which has a "chrono" setting - "energy saving feature which fires the boiler at regular intervals to maintain a set temperature, achieving a constant ambient environment for the user"

Does this option actually save energy or is it more efficient to use the more conventional "boiler switches ON when below set temperature and OFF when
above" ?

The "chrono" setting may be a little more efficient because the house is less likely to be overheated due to overshoot of the thermostat. The main advantage though should be a more constant temperature. Try it and see.
