MLR003R: Temperature Control Loop

In the following situations, the device will estimate the room temperature:

• The device has never received an external sensor temperature

• The last communicated external sensor temperature was “0”

• It has been a long time since the device last received communication of an external sensor temperature (see FPORT 0x09 for adjustment of this expiry time)

• The device has become disconnected from the Gateway

See FPORT 0x08 for the Temperature Estimation Algorithm, and for adjustment of the algorithm.

To achieve the instructed room temperature, the device applies the PID algorithm.

See FPORT 0x07 for adjustment of the PID coefficients and Offset Percent.

The device considers moving the motor every 5 minutes.
