I am fitting a weather compensator to control a heating boiler!!
The instructions recommend a twin cable of 1.5mm with a max length of 35m for wiring the out door sensor!!
As the run of cable to the sensor will only be 3m max would 1.00mm cable be adequate???
The resistance of the thermistor varies from 480-560 ohms!!
What is the resistance per metre of 1.00mm/1.5mm cable??
Or am I missing something out of the equation??
