TEMPERATURE ADJUSTMENT:
This pool heater is equipped with a digital thermostat which allows the user to select the desired water
temperature. The heater will then function automatically to maintain the desired temperature. The heater has
3 modes of operation:
1. STANDBY: in this mode, the heater will not function to heat the water.
2. SPA: in this mode, the heater will automatically function to maintain the water temperature setting
for SPA mode.
3.
POOL: in this mode, the heater will automatically function to maintain the water temperature set-
ting for POOL mode.
Use the MODE button to change modes. The indicator lights will illuminate to show which mode the
heater is currently in. Each mode has its own temperature setting, allowing the user to have 2 individual
pre-set temperature settings. To adjust the temperature while in SPA or POOL mode, use the UP and DOWN
buttons. The numeric display will
fl
ash to indicate the temperature setting is being displayed / adjusted. When
the numeric display is not
fl
ashing, the actual water temperature is being displayed. The temperature settings
for both SPA and POOL modes are initially set at the factory to 65°F. The minimum allowed settings for SPA
and POOL modes are both 65°F. The maximum allowed settings for SPA and POOL modes are adjustable up
to 104°F using the temperature lockout feature (see page 25).
After selecting SPA or POOL mode or adjusting the temperature setting, it is normal for the heater to
delay up to 10 seconds before the heater starts operating. This delay is an internal self-test of the heater. On
occasion, the numeric display may show a diagnostic error code; refer to list of diagnostic err
or codes in Fig-
ure 21. Pressing the MODE button to cycle to STANDBY and back to SPA or POOL will clear a diagn
ostic
error code. When clearing a diagnostic error code this way, it is normal for the heater to delay up to 5 seconds
before resuming normal operation, assuming the diagnostic error code does not re-appear.
