When using a TEC module with the Thermostat, the Thermostat expects the thermal load (where the thermistor is located) to cool down with a positive software current set point, and heat up with a negative current set point.
|
||||
|
||||
If the Thermostat is used for temperature control with the Sinara 5432 DAC "Zotino", and is connected via an IDC cable, the TEC polarity may need to be reversed with the `output <ch> polarity reversed` TCP command.
|
||||
|
||||
Testing heat flow direction with a low set current is recommended before installation of the TEC module.

```

pwm 0 max_v 1.5
