Installation Guide - DC Temperature Controller
Configuration
For optimum performance it is necessary to configure the controller to match the maximum total power requirements of all of
the connected fans. The maximum power rating for each fan will be available on the fan label or datasheet.
For example, if running 4 fans rated at 2 Watts each, the total power requirement is 4 x 2 = 8 Watts. The controller must then
be configured to the lowest setting which exceeds the total power. In this case, 11 Watts.
To configure the controller, set the jumper links shown as shown in the connection diagram.
Initial Start-up
Due to minor differences in motor types and electronics, some fans may work better than others with the default settings.
If the fan or fans fail to run on initial start-up, first check the following;
If the controller still does not operate correctly, please refer to the troubleshooting guide.
A detailed technical specification for this controller and a list of ebm-papst fans which have been tested for compatibility is

if more than one sensing output wire from a 3-wire fan is connected with this function enabled.
Only applicable to 3-wire fans with appropriate outputs. Alarm monitoring will not operate correctly
Soft start setting
The recommended setting is for a soft start with the rate of fan speed increase being managed by the controller
but a small number of fan types will only work with a faster ramp up speed. If the fan(s) fail to start properly, switch
this function off using the DIP switch and try to start the fan. If it makes no difference, reset the dipswitch.
Power setting
The power requirement of some fans means that they may be on the borderline for a particular power configuration.
A slight increase in demand during start-up for example, can be detected as an over current condition by the
controller causing an alarm condition and shut down of the fan.
If the fan does not start or starts then stops, move the power configuration jumper link to the next highest setting.
If it makes no difference, return it to the original setting.
