Figure 3 is a dimensioned, bottom view of the Wall Mounted
Controller. The modular design isolates the control circuitry from the
contacts making it possible to make the connections and then close
the compartment. Adjustments can then be made only in the control
area, without having to open the contacts compartment.
Figure 4 is a dimensioned front view of the Wall Mounted Controller.
The molded, mounting holes in the corners provide for quick and
secure installation. No additional hardware is needed for mounting.
All electrical connections and controls are located on the front of the
instrument so that adjustment can be made without having to
remove the unit.
