SECTION III. INTRODUCTION OF DDTC

The DDTC board, shown in Figure 7, is a digital temperature controller capable of controlling the pool,
spa or both to a minimum temperature of 65° F. (below 65° F. display reads "Off") and a maximum of
104° F. The DDTC board also functions as a system status indicator, using LED lights and programmed
error codes.
During normal operation, the DDTC will display the current temperature of the water returning to the
heater, depending on which mode has been selected, "Pool" or "Spa". This is accomplished by a
thermister (sensor) on the inlet port of the water header of the heater and working in conjunction with
the internal microprocessor controlling the operation of the heater.
Changing the desired pool or spa temperature is easily done by simply depressing the appropriate up or
down arrow until the display reads the desired set-point temperature. For example, set pool to 78° F.
and the spa to 104° F., when releasing the up or down arrow the display will flash once then return to
the current temperature.
At any time, you wish to know the temperature setting of the pool or spa, simply press the appropriate
up or down arrow, the display will flash once and display the set-point temperature for three (3) seconds,
then flash once again and return to the current temperature.
