I have a boiler control and the building is too hot during mild outdoor weather (50 to 65ºF, 10 to 20ºC). How can I turn down the heat?

During mild outdoor weather, the building can get too hot because the boiler must maintain a minimum temperature while operating to prevent damage. The control has an automatic warm weather shut down that turns off the boiler. Lowering the warm weather shut down setting will reduce or prevent over heating.

On a three-button control, press all three buttons at the same time, then let go. The control is now in the Adjust menu. Press and release the Item button until you find the WWSD (warm weather shut down setting). Then press the down arrow button to reduce the setting. Wait 20 seconds and the control will record the setting and go back to the View menu.

On a four-button control, press the menu button to enter the Adjust menu. Press and release the Item button until you find the WWSD (warm weather shut down setting). Press the down arrow button to reduce the setting. Wait 20 seconds and the control will record the setting and go back to the View menu.

In general, large apartment buildings can have the WWSD set to 55 to 65ºF (12 to 18ºC) and residences can have the WWSD set from 65 to 70ºF (18 to 20ºC).
