Estimate of energy production
:
An estimate of energy transfer from Source (solar panels) to Storage (solar storage tank) can be
determined by multiplying
Δ
T·hours by associated constant below.
Δ
T·hours is displayed with alternating numbers. When °F or °C segment is off, thousands are displayed.
When °F or °C segment is on, units are displayed.
Ex.
Energy Transfer =
Δ
T·hours x K
Δ
T·hours = 005 (
thousands
) 225 °F(
units
) = 5225 °F·hours
Energy Transfer = 5225 x 0.0377 = 197 kWh
Calculation provides only a rough estimate of solar energy captured. It is not an accurate indication of
displaced electric or fossil fuel energy. Losses inherent to electric or fossil fuel hot water tanks are not
considered. Estimate of energy production should in no way be used to assess energy displacement for
billing purposes.
Program (PRGM) Mode
:
To enter program (PRGM) mode, push and hold all three buttons. By pushing
Item
button, Controller
cycles through program settings, including operating mode and default temperature units (°F or °C).
Modification of PRGM operating mode, from Automatic (
Au
) to On (
On
) or Off (
oFF
) is only
permitted to purge air from pump during charging procedure or to test system during
periods of low insolation. Modification of PRGM mode is also permitted to change default
temperature units between degrees Fahrenheit and degrees Celsius.
ALTERING, MODIFYING OR CHANGING ANY OTHER
PRGM
SETTINGS THAN THOSE
DESCRIBED ABOVE IS NOT PERMITTED [except modification of
Maximum Storage setpoint
temperature
for Space-Saver
TM
(single-tank) Appliance].
Changing PRGM settings other than operating mode or temperature units may lead to
equipment malfunction or damage, to poor performance, and to health and safety risks.
Altering any default PRGM setting other than the operating mode or temperature units will
void the warranty.
