Maximum Valve Operation:
A maximum of 2 valves, any where on the system, may operate simultaneously, of either
same number or combinations of different numbers. The 2 valve maximum does not
include the Master valve or Pump Start Relay. Controller specifications are based on
a Standard 24VAC irrigation valve solenoid rated with a maximum 350 mA inrush and
a maximum 250 mA holding current at 24VAC. Controller is not compatible with Low
Power / Diode Bridge solenoids.
Wire Connectors:
One of the most critical installation requirements of a PRO 2 two wire system is the
quality of your wire connections. If you follow these directions you will have a reliable,
dependable control system for many years. It is suggested to solder all decoder (red
wire) connections to your main two-wire run. Install the soldered two-wire connection in
a waterproof underground connector housing. When soldering is impractical, a water-
proof “dry-type” Hit Products DBC-BR wire connector is required. The above mentioned
product will provide an uncontaminated, reliable dry connection.
A DBC-BR Kit (1 each) is included with each Pro 2 Decoder.
