Via a temperature threshold, the heatsink temperature of the controller can
be monitored:
Æ’ Adjustable threshold (OH4) under C0122
– The reset point is 5° C below the adjusted threshold.
ƒ Fixed threshold (OH) = 85° C
– The reset point is at 80° C.
The response for exceeding the adjustable threshold can be set under C0582.
