Replacing old Honeywell thermostat
marked 20(4)A - do I need to get a new thermostat with the same
rating, or would a 10(4)A be up to the job, as that's the highest I
can find locally.
If this is for a normal central heating system, then the entire system will
be fused at 3A, so anything that can cope with that would be fine.
