Page 7: Wiring Instructions
Wiring Instructions This section explains how to wire individual devices to the Smart Steam Control 289 . Please refer to technical data table on pg 36 for sensors that are included in the standard packaging of the Smart Steam Control 289 . Pressure Sensor 089 (Terminals 1, 2, 3) An optional Pressure Sensor 089 (sold separately) can connect to the 289 to provide staging for a second steam boiler and to monitor steam pressure up to 15 psi (104 kPa) . - Page 8 • Connect 18 AWG or similar wire to the two terminals provided in the enclosure and run the wires from the sensor to the control . Do not run the wires parallel to telephone or power cables . If the sensor wires are located in an area with strong sources of electromagnetic interference (EMI), shielded cable or twisted pair should be used or the wires can be run in a grounded metal conduit .
