Advanced settings:

By pressing the Select key in the View mode while viewing the Boiler ΔT reading (or the Supply Sensor temperature if the Pool Supply sensor is connected), the Boiler On hours will be displayed, indicated by the text BOIL ON in the display. This is the total number of hours the pool heater has been heating the pool.

By pressing the Select key in the Adjust mode while viewing the Pool DIFF setting, the Boiler Inlet Minimum setting will be displayed, indicated by the text BOIL IN MIN in the display. The control will adjust the position of the 3-way automatic bypass valve in order to maintain the inlet temperature at this setting. The default is 130°F.

By pressing the Select key again, the Boiler Maximum setting will be displayed, indicated by the text BOIL MAX in the display. The control will shut off the heater whenever the outlet temperature from the heater exceeds this setting. The default value is 200°F.

If a Pool Supply sensor is connected, then by pressing the Select key again, the Supply Target setting will be displayed, indicated by the text SUP TARGET in the display. The control will shut off the

heater whenever the pool supply temperature exceeds this setting. The default value is 100°F.

If a Pool Supply sensor is connected, then by pressing the Select key again, the Supply Differential setting will be displayed, indicated by the text SUP DIFF in the display. After the control has turned off the heater because the pool supply temperature exceeded the Pool Supply setting, the pool supply temperature must drop by this amount before the control will allow the heater to start up again. The default value is 20°F.

By pressing the Select key again, the Valve Speed setting will be displayed, indicated by the arrow pointing to the text SPEED on the overlay. This setting is used to control the responsiveness of the 3-way automatic bypass valve, and should only be adjusted under the direction of Lochinvar’s Technical Services personnel. The default setting is 20 seconds.

By pressing the Select key again, the pump Delay setting is displayed, indicated by the DLY on the display. This is the time that the heater pump will continue to run after the control turns the heater off. The default value is 20 minutes.
