3.4.2 Controller Temperature
Depending on the ambient temperature and the placement of the controller additional cooling may be
required (see Figure 24). 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.
Figure 24: Temperature curves of controller LPC-2000 vs. flow and speed
(For pumping with pump head LPP-2000.6/7 and motor LPM-2000.2)
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.
