Fig. 6: Typical Water Sensor

•Hydronic installations may require outdoor reset function. See page 11, and screen 02.

•Ensure shielded cable length does not exceed 300 feet. Use 18 AWG shielded wire for sensor con- nections.

•Must be installed in properly-sized conduit with no other wiring.

NOTE: Piping diagrams in this manual are not intended to replace an engineered piping system.

•Locate the water sensor as shown in Fig. 6.

NOTE: When the system involves a variable-speed pump, it is recommended that the temperature sensor be installed in the tee connecting boiler outlet piping to the system. This is to ensure the control can respond to the changing conditions of the system by placing the sensor as close to the blend location as possible and then provide an appropriate and measured response to maintain desired system delivery temperature.
