￿CAUTION

NOTICE

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

The sensor supplied contains an Auto Reset High Limit (194°F).

Install tank sensor

The tank sensor is a dual sensor which controls the temperature of the tank from the boiler(see FIG. 5-3). The tank sensor has a built-in high temperature limit set at 194°F.

1.Install the sensor inside the tank as depicted in FIG. 5-3.

2.Connect the wire leads to the DHW Tank Sensor (AUX) connection point on the Knight boiler connection board (see FIG. 5-3).

3.The Knight boiler will automatically read the sensor and default the tank temperature setting to 125°F.

4.Adjust the tank set point program. Reference the Knight Installation and Operation Manual for a detailed explanation of the tank set point program.

Connect tank sensor

1.Turn OFF the power to the unit. Use wire strippers to strip one inch of insulation from the ends of each wire that will be spliced.

2.Splice the two ends of bare wire by twisting them together with a pair of electrical pliers. Turn the pliers three or four times to make a sufficient connection.

3.Attach a wire nut at the point where the two wires have been twisted together. Twist the wire nut until it fits snugly, or until it cannot be twisted any more.

4.Wrap the wire nut and the two wires with electrical tape to secure the connection. Cover any exposed wiring with electrical tape.
