3.4.2 Controller Temperature
Depending on the ambient temperature and the placement of the controller additional cooling may be
required (see Figure 20). To improve cooling of the controller, place the device into a moving air stream. If
the controller is mounted in a compact area or adjacent to additional heat sources (e.g. a 2
nd
controller)
ensure that there is sufficient ventilation.

(for pumping with pump head DCP-2000.2 and motors LPM-2000.x)
The above curves are measurements of the controller temperature at 25°C ambient. Equation (Eq. 2) shows
how to calculate the controller temperature for at other ambient temperatures based on this curve.
