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 setting 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 flash to indicate the

temperature setting is being displayed / adjusted. When the numeric display is not flashing, 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 below).

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 error codes in Figure 4. Pressing the MODE button to cycle to

STANDBY and back to SPA or POOL will clear a diagnostic error code. When clearing a

TEMPERATURE LOCK-OUT

The digital thermostat in this pool heater allows the user to lock the maximum temperature

setting allowed. This feature is useful for preventing unauthorized users from manually adjusting

the temperature settings higher than desired. On a new heater, the maximum allowed

temperature lock settings are initially set at the factory to 90°F for POOL mode, and 104°F for

SPA mode. To adjust these settings, use the following procedure:

1. Use the MODE button to put the heater in STANDBY mode.

2. Press and hold both the UP and DOWN buttons at the same time.

3. After 3 seconds, the thermostat enters maximum temperature lock adjustment mode.

4. The SPA indicator light illuminates and the numeric display shows the current SPA mode

maximum temperature lock setting. Both the SPA indicator light and the numeric display

flashes rapidly when in adjustment mode.

5. Use the UP and DOWN buttons to set the desired maximum temperature lock setting.

When finished, press the MODE button.

6. The POOL indicator light illuminates and the numeric display shows the current POOL

mode maximum temperature lock setting. Both the POOL indicator light and the

numeric display flashes rapidly when in adjustment mode.

7. Use the UP and DOWN buttons to set the desired maximum temperature lock. When

finished, press the MODE button.

8. The heater will return to STANDBY mode.
