Thermostat, Hayward H-Series, Above Ground

The Hayward Thermostat (IDXTST1930) is a temperature control device used in Hayward pool heaters to regulate and maintain the desired water temperature.

• Senses Water Temperature:
• The thermostat monitors the current water temperature flowing through the heater.
• Controls Heating Activation:
• If the water temperature is below the setpoint, the thermostat signals the heater to turn on.
• Once the desired temperature is reached, the burner shuts off to prevent overheating.
• Ensures Efficient Operation:
• Maintain a consistent water temperature, avoiding unnecessary heating.
• Works with safety sensors to shut down the heater if unsafe temperatures are detected.
