Check/fix temp issue with 5v1 model

Investigate/fix temperature issue with model 5v1

Temp values for thermistor temp do change with a change in temperature, but the offset/scale is off significantly. Looks like a resistor value problem or a Beta value problem

Issue Details:

The Temp DH value returns the correct value but Temp DHt does not. Appears to be limited to model 5v1 but verify this is the case!

Potential Solutions:

Looks to be a scaling/offset issue, verify correct beta value and thermistor/resistor values. Likely just a coefficient issue for the 5v1 model

Example Values:

Temp DH [C]	Temp DHt [C]
27.61	75.31
23.32	63.97
13.64	55.84
7.32	47.18
3.25	43.36

Note: Temp DH is correct value, Temp DHt is unknown incorrect value
