Temperature Control Settings

There are three setting knobs on the temperature control unless your unit is specified as a boiler only with an outdoor air reset option. If your unit is a boiler only with an outdoor air reset option, there are additional controls for this option. They are explained under Outdoor Air Reset Option, page 22.

The three setting knobs on the temperature control are for Set point, Differential, and High-Fire Offset (see Figure 28).

TEMPERATURE ADJUSTMENT

Operating Temperature Control

NOTE:

The temperature controller is pre-set at the factory with test settings. You may need to adjust the settings to meet your specific needs.

￿WARNING

Return water temperatures must not be less than 140°F. If lower return water temperatures are required, follow the instructions for Low Temperature Bypass Requirements or Three-Way Valves, see page 35.

Locating Temperature Control

Remove the control panel door on the front of the unit in order to locate and access the temperature control.

Maximum Set Point Determination

The maximum set point for the control is factory set. Boilers can be set to 240°F max., water heaters are set to 190°F max., and specialty state and local codes to 200°F.

These maximum set points are established by cutting the OJ1 and OJ2 jumpers located on the right side of the temperature controller. The maximum set point is determined as shown below in TABLE-K.

Anytime that OJ1 is the only jumper cut, a new overlay is required under the Set Point knob on the temperature controller because the scale has changed to a maximum of 190°F.

Anytime the OJ2 jumper is cut (with or without OJ1), a new overlay is required under the Set Point knob on the temperature controller because the scale has changed to a maximum of 200°F.
