How to configure thermal runaway settings for Enclosure Heater ?

I'm not using a M307 to configure an enclosure heater which is probably my problem, but I followed a guide on the Duet Site.;
My config is below.
However I keep getting thermal cutouts because the thermal runaway setting default is for a hotEnd and expects 1.7 C increase every 1 sec which is too high for an enclosure heater settings.
; H=2 Hot End 2 / Chamber Heater
M141 H2 ; Assign chamber heater to heater 2
M305 P2 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for heater 2
M301 H2 B1 ; Set heater 2 to bang-bang mode
M143 H2 S50 ; Set temperature limit for heater 2 to 50C
I cant seem to see where I can override the default thermal runaway settings
Any help appreciated
You can only change the heater protection settings using M307. If you want to set the patameters manually, see duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control#Section_Setting_the_model_parameters_manually.
