to the right. In the upper-left corner of the Overview screen, you
can see the total power and current draw from the controller and
the input voltage from the power source. Below that, you can see
the ambient temperature and humidity data from the environmental
sensor and the calculated dew point.
The Overview menu is also where you can turn each output port on or
off, including both dew heater ports and the output power port. If you
are remotely logging into the PC connected to the controller, you can
remotely turn your devices on and off here. For the power port, simply
use the ON/OFF button. For the dew heater ports, select "Manual"
and set the power level to zero.
As discussed previously, the controller will automatically shut off its
ports if there is too much load on one of the ports (greater than 84W)
or if the total load on the controller exceeds 120W (10A max current).
If this happens, the Fuse Blown Notification will appear, and you will
see a "RESET FUSE" box next to the affected port(s) in the Overview
screen (Figure 15). To re-enable a port after it has been automatically
disabled, first reduce the load on the port as needed. Then, click on
the "RESET FUSE" box to re-enable power to the port.
Fig 15
If the power draw on a port exceeds 84W, the port will automatically shut off. To re-enable,
reduce the load on the affected port and then click the RESET FUSE box.
NOTE: If the total load on the controller exceeds 120W (10A max
current), you will need to re-enable all ports.
Under each Dew Heater port, you'll find buttons to change from Auto
"smart" control mode to Manual control mode:
- If you select Manual Mode, you will need to indicate the desired
power level. This is a number between 0 and 100—the percentage
of maximum power to the dew heater connected to the port. Once
you have entered your desired value, press ENTER.
To turn a dew heater port off, select Manual control and set the
l
slider to 0%.
- If you select Automatic Mode, you will need to set the "aggression"
level. This is a number from 1 (lowest aggression) to 10 (highest
aggression) that indicates how active the controller is when
preventing dew. A higher aggression setting will use more
power but will provide the highest level of dew prevention during
changing environmental conditions. In general, you can use a
lower aggression setting for warmer and drier observing sites and
a higher setting for cooler and more humid observing sites. Also,
use a higher aggression setting for larger apertures and lower
aggression if you are using a dew shield or it is windy. Use the

slider to set the aggression. If you are unsure of what aggression
setting to use, try 5 (the default setting) initially.
You can rename each port in the Overview screen by clicking on the
name of the port. The Port Name Editor window will appear (Figure
16), and you can enter the new name. Click the OK button when
done, and the new name will appear for the port. This will help you
keep your controls organized, as you can rename each port for the
connected device. For example, you can rename your ports "8-inch
Dew Heater Ring" or "CGX Mount."
POWER GRAPH
Select "Power Graph" from the Dew Heater menu to bring up the
Power Graph window (Figure 17). You can also access the Power
Graph directly from the Overview screen by clicking on the shortcut
arrow icon next to the word "Power" on the upper-left side of the
Overview screen.
The Power Graph shows power usage over time for all devices

connected to the controller's dew heater ports and output power port.
Each color line on the graph represents a different port. If you wish to
change the color for a port, mouse over the port and right-click.
You can hide a port from the graph by clicking on the circle to the left
of the port's name. To re-enable its line on the graph, simply click on
the circle again.
To "zoom in" to a specific time range on the graph to see more detail,
use the "+" and "-" circles at the bottom right of the graph. You can
