WHP Controller
The WHP Controller may be installed in any convenient protected location. Observe the
recommended environmental limitations for the WHP Controller when selecting a
installation location. The environmental limitations are a temperature range of 10°F to
149°F, and a maximum operating humidity of 90% RH non-condensing.
The WHP Controller may be mounted by fastening to a flat surface through the mounting
plate. The unit is mounted by four (4) screws in the corners. Select the correct screws or
other fasteners for the type of mounting material being utilized.
