What is switching differential?
Without a switching differential your boiler would
stop the instant it reached the desired temperature
then start to fall where it would instantly kick back in
again and be stuck switching your boiler on and off
repeatedly. A switching differential creates a band
around the temperature to allow the set temperature
to be maintained. We recommend using 0.5°C unless
you have a specific reason not to.
