This Honeywell sundial system, central heating control with ST712
programmer seems to be using, according to an Efergy monitor....13Watts.....£15 a year.
Is this normal or am I reading the monitor wrong. Have checked it against a known wattage.
Not urgent been like this for 10 years.
Thanks for reading.
