Remote control is initiated by engaging the RMT switch (located on the CP 52S front panel). The ZR 1 may be installed in a standard electrical box and finished with a Decora??? plate.
The ZR 1 connects to the CP 52S through a 5-pin Euroblock connector. The remote uses 5 wires with 2 bits for Zone Program selection (active low Gray Code), a common shield/gnd and two wires for ratiometric DC control of Zone Level. Selector logic is active low Gray Code with pull-up provided in the CP 52S. Control may be a simple switch closure to GND or 5 volt TTL.
