Correct Sensor B Value

[David Pickford]

hi everyone,

Do any of you know the correct Sensor B Value for an SPA analogue 2 clock dash fitted to an Atom 2? I have replaced my dash and am having trouble getting a correct water temperature reading.

SPA quote 3977 as the default, but set at that value the water temp. reading is 68 degrees centigrade at cold, which is obviously way out.

The Sensor RT2 value on my dash is set to 318, which is what SPA say is their default setting.

Any help would be much appreciated.

Hi Dave,

Any chance you have Temp Sel set to Fahrenheit ?!

Edit : Just read out the values from my AA3-245 which ought to be the same

Sensor B is 3988
RT2 is 045

I've attached the SPA Kit Dash manual if it helps ..

Many thanks John, I will try those figures instead of the SPA defaults to which it's currently set.

Much appreciated.
