Status And Diagnostics - Raypak 106 User's Installation And Operation Manual

NOTE: Both the POOL and SPA setpoints will revert back to
65°F (18°C) and the POOL and SPA maximum temperature
settings will be 104°F (40°C). These setpoints will need to
be readjusted to desired settings.
NOTE: The LCD temperature display may not agree with
the temperature reading of your pool or spa thermometer.
The heater reads the water temperature at the inlet. Due
to the circulation characteristics of any pool or spa, the
water temperature at the inlet to the heater may differ
from that observed at a given location in the pool or spa.

5.4. Status and Diagnostics

The P-156 has a digital thermostat that is programmed
to display a variety of status and diagnostic messages,
depending on the operating conditions.
The following heat status messages are displayed in Pool,
Spa, and Remote modes when there are no active fault
conditions.
