Lochinvar F0600187510 - Manual (Page 41)

By pressing the Select key, the Pool Target is shown and the text
TARGET on the display. This is the pool temperature set point.
By pressing the Select key again, the Boiler Inlet Temperature is
shown, indicated by the text Boil In. This is the temperature of the
water going into the pool heater. Note that it is different than the
temperature of the water coming from the pool.
By pressing the Select key again, the Boiler Outlet Temperature is
shown, indicated by the text Boil Out. This is the temperature of
the water coming out of the pool heater, before it is mixed with the
water from the pool.
By pressing the key Select again, the Boiler Rise is shown, indicated
by the text Boil
ΔT. This is the difference between the inlet and
outlet temperatures at the pool heater.
If the pool supply sensor has been installed and connected, by
pressing the Select key, the Pool Supply Temperature is shown,
indicated by the text SUP. This will show the actual temperature of
the water returning to the pool.
If in the Advance mode (rear dip switch set to “0” position), 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. To clear the Boiler On hours press the Up
and Down Arrow keys simultaneously. For a detailed explanation
of the advance settings, see Appendix B on page 59 of this manual.
By pressing the Select key again, the display returns to the Pool
Temperature display.
Programming Mode
In order to adjust any of the settings, it is necessary to enter the
Adjust mode. This is done by pressing all three buttons
simultaneously for one second and it will change from View to
Adjust. The setting shown can be adjusted (within it’s acceptable
range) by pressing the Up or Down Arrow key.
The default display shows the Pool Target temperature indicated
by the arrow pointing to the text POOL on the overlay, and the text
TARGET on the display. This is the temperature of the water from
the pool at which the pool heater will turn off. The default is
85°F/27°C.
By pressing the Select key again, the Pool Differential temperature
is shown, indicated by the arrow pointing to the text POOL on the
overlay, and the text DIFF on the display. This is the number of
degrees below the Pool Target temperature that the pool
temperature must drop before the pool heater will turn on. The
default is 4°F/2°C.
By pressing the Select key again, the Temperature Units will be
displayed, indicated by the text °F or °C. This is the units in which
the temperatures are shown. The default is °F.
Installation and Service Manual
By pressing the Select key again, the Pool Target will be shown once
more. To return to the View mode, simply stop pressing any
buttons for 25 seconds.
Note: The control values programmed into memory will not be
lost because of a power failure.
Error Messages Displayed by the
Temperature Controller
There are six error messages that can be displayed in response to
software or hardware problems with the pool heater's internal
temperature control. The error codes that may be seen on the display
are:
E01 - The internal memory of the microprocessor in the
temperature control has a read error at power up. This error cannot
be field repaired. Replace the pool heater's temperature control if
the error persists.
SHr - There is a short in the temperature sensor. Make sure sensors
are properly installed, wired and connected to the control. Correct
sensor installation or replace sensor.
OPn - There is a break in the wiring to the temperature sensor.
Make sure sensors are properly installed, wired and connected to
the control. Correct sensor installation or replace sensor.
FP - The burner is not running 2 minutes after the start of the call
for heat. Check ignition control codes.
E02 - The outlet temperature from the pool heater reached its
maximum setting. Check the bypass pump and mixing valve.
E03 - The inlet temperature into the pool heater was below its target
temperature for more than 15 minutes. Check the mixing valve.
