Installing the Station Wires and Power Wires
1. Disconnect the primary power source to the existing satellite controller.
2. Unlock the satellite cabinet front cover and the RDR unit door to access the station terminals.
3 For exterior installation, install 1/2" (13mm) flexible water-proof conduit between the satellite cabinet and the RDR
unit. See Figure 3. Separate conduit must be installed for the 24 V a.c. power wire and station wires.
4. Using 14–16 AWG (2.5–1.5mm
satellite terminal strip into the RDR unit. Label and identify each wire for connection to the RDR output board
terminals.
5. Secure each station wire and the valve common wire to its associated RDR station terminal; i.e., satellite station 1
connected to RDR unit station 1, etc. Refer to Figure 4 for the satellite terminal configuration and Figure 5 for the RDR
unit terminal configuration.
6. Route 24 V a.c. power and common wires from the terminal block and secure both wires to the RDR transformer
terminals. See Figure 5.
Note: The RDR unit requires a 24 V a.c. power supply. If installing on a controller other than the VT 4000, locate a
24 V a.c. power source from within the controller or from an outside source to connect the RDR transformer.
CAUTION: Up to three valve solenoids can be connected to each station, not to exceed 0.75A maximum
output per station. During operation, a maximum of five solenoids can be operated simultaneously, not to
exceed 1.25A maximum current draw. Exceeding these limits can cause equipment damage.
