It's in the manual.

MAXIMUM TEMPERATURE SET POINT
1. Unbolt and remove the door panels (see Figure 32).
2. Access the control panel board on the underside of the top cover. Locate
the yellow button on the corner of the control board.
3. Push the Max. Temp. Set Point button on the back of the control board (see Figure 33).
The following sequence should happen:
A. The unit will come on and the POOL ON light will come on.
B. Press the UP TEMP or DOWN TEMP pad (on TOP of the panel) to set
maximum pool temperature.
C. Wait up to 30 seconds; the POOL ON light will go off and the
SPA ON light will come on. To override the time delay, push the Max. Temp. Set Point button again.
D. Press the UP TEMP or DOWN TEMP button on the control panel and set maximum spa temperature to 104°F (40°C) or less.
E. Wait up to 30 seconds; the SPA ON light will go off and the unit will shut down. To override the time delay, push the Max. Temp. Set Point button again.
4. Reinstall the access door panels.
