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.
