Environment
- Adjustable 10k Thermostats
- Menta
- STR-102
- STR-103
- STR-104
- STR-105
- STR-106
- STR-107
- STR-201
- STR-202

Cause
Interfacing a STR to Xenta I/O
Resolution
Program an Analog Input to a Universal Input of an I/O Module

The Expression Block is taking the hard coded -9 to 9 input and making it adjustable from the front end.
In simulation with a Calibrated Range of 5 the following setpoint results are produced:
| Analog In | -9 | -8 | -7 | -6 | -5 | -4 | -3 | -2 | -1 | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
| Setpoint | -2.5 | -2.2 | -1.9 | -1.6 | -1.3 | -1.1 | -0.8 | -0.5 | -0.2 | 0 | 0.2 | 0.5 | 0.8 | 1.1 | 1.3 | 1.6 | 1.9 | 2.2 | 2.5 |
Note: This example is for a non-linear input, with a setpoint adjust of +/-9.
For a metric calculation, use a setpoint adjust of +/-5 and change the calculation in the expression block to A*B/10.
