BOILER OPERATING

TEMPERATURE CONTROL

The operating temperature control is located in the control panel, behind the control panel front access door. The sensing element for the operator is placed in a bulb well installed in the heat exchanger. Carefully observe the discharge water temperature on the initial boiler on cycles. The exact temperature set point is based on your system’s requirements. Turn the control set point dial to the desired operating water temperature. Observe the boiler discharge temperature after each set point adjustment to ensure proper operation.

ROOM THERMOSTAT OR REMOTE

THERMOSTAT CONNECTION

TO TERMINAL STRIP

A room thermostat or remote temperature control may be connected to the boiler. The room thermostat should be installed on an inside wall, away from the influences of drafts, hot or cold water pipes, lighting fixtures, televisions, sun rays or fireplaces. Follow the manufacturers instructions supplied with the thermostat for proper installation and adjustment. The boiler is equipped with a terminal strip on the left side of the control panel to allow easy connection (Figure 48).

Remove the jumper between the R and W terminals on the terminal strip. Refer to the chart in this section to determine maximum allowable length and wire gauge recommended to connect the switching contacts of the room thermostat to the R and W terminals on the terminal strip. Connection to the terminal strip will allow the room thermostat to make and break the 24VAC boiler control circuit turning the boiler on and off based on the room ambient temperature requirements. Set the boiler operating temperature control as described in this section
