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.
