1.Remove the thermostat from its base and set the SW2 switch to MENU.

2.Reinstall the thermostat. The thermostat is now in configuration mode. The first digit flashes to indicate that the first item of the menu can now be modified.

3.To modify the setting, use the up/down arrows. Refer to the adjacent tables.

4.Press Override to save the new setting and go to the next item.

5.Repeat steps 3 and 4 for remaining items.

6.When the configuration is done, set the SW2 switch back to NORMAL.

ABBREVIATIONS

NSB - Night setback (number of degrees the thermostat will be set back upon receiving a setback signal)

SSR - Solid state relay (used with fast cycling electric heaters, SSR's are a quiet alternative to electromechanical relays. They're typically included with electric duct reheat equipment)

SCR - Silicon controlled rectifier (similar to an SSR, SCR's are also quiet and capable of switching very high current. If used, they're usually included with the equipment)

N.C. - Normally closed N.O. - Normally open
