(we're not kidding - we get a lot of e-mails with questions that are already addressed in the Frequently Asked Questions web page)

These commands are valid for Version 5.00 and higher

The SET command has multiple parameters.

Update Interval determines the time between sensor readings.  Set to 0 to stop polling (Note: this is only available in versions 5.11 and higher).  Enter the time in decimal minutes.

Relay Off Timer determines how much time to wait between turning on ANY relay and turning them ALL off.  Enter the time in decimal minutes.  Enter 0 to disable this function.

F or C Display determines how temperature readings are displayed.  Enter F for Fahrenheit or C for Celsius.

Serial # Display - set to Yes if you want TEMP05 to display the 1-wire ID of all sensors.

Wind Dirn Reverse - set normally to N.  Set this to Y if you accidentally installed the wind direction PCB upside down in your weather station OR if you want to display wind direction as the FROM direction instead of the TO direction.

DIS output explanations

Sensor numbers do not necessarily match up with the output from the regular sensor output readings.  This is intentional.  The sensor numbers in the DIS output are the memory locator and are used by the DEL, RST, ONA, OFA and TYP commands.  The sensor numbers in the scan output are sequential numbers for each type of sensor.

An OK will be displayed following the sensor type to indicate that the Cyclic Redundancy Counter (CRC) checksum of the sensor's serial number is good.  If the serial number has a bad CRC, an NG will be displayed.  The checksum is validated during the output of the sensor display.

Letters following the DS2423 and DS2438 indicate the TYPe of sensor equipped.  This is a manual input and will be set following first discovery of the sensor via the INI command, and also following a power-up of the TEMP05 for the DS2423 sensors that do not have built-in battery backup.  The letters designate the sensor type per the following table.

Sensor Types

Following a display of the sensors installed, the output of the DIS display then shows the TEMP05 settings that you entered via the SET command.  The DEBug mode is then shown.  To turn on or off the DEBug mode, use the DEB command.

Following that, the DIS display then checks to see if all temperature sensors are parasitically or locally powered.  If ANY temperature sensor connected to the 1-Wire bus is set to parasitic mode, then the display will show "some sensors parasitic powered".  The same display will result of ANY DS2438 devices are present on the 1-Wire bus.

Following that display the DIS output proceeds to show how many temperature sensors are installed, by type.  The DS18B2 type indicates a DS18B20 sensor.  The DS1820 type is valid for DS1820, DS18S20 and DS1920 sensors.
