+1 on the ARP (temperature sensing, power interrupter). It also gives visual indications of temperature readings of the boiler system so you know if the fridge is operating properly.
I installed one myself a few months ago & like it....iirc - if the boiler gets above 420* (f) (default), the ARP will terminate power to the fridge, until the boiler cools down - then it will try to turn it on again (if it over heats it'll kill the power again & eventually permanently).
