Status And Diagnostics - Raypak 259 Installation & Operating Instructions Manual

NOTE: The LCD temperature display may not agree with the temperature reading of your pool or spa ther-
mometer. 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.

STATUS AND DIAGNOSTICS

The digital thermostat models are programmed to display a variety of status and diagnostic messages, depend-
ing on the operating conditions.
The following heat status messages are displayed in
Pool, Spa, and Remote modes when there are no
