-
Surface-Mount Installation:
- The thermostat is mounted on the surface, making installation simple. Its mounting design allows it to be positioned for optimal temperature sensing and performance.
How the Robertshaw ST 12-93K Works:
-
Temperature Sensing:
- The thermostat continuously senses the temperature of the water in the system. When the water reaches the desired temperature set by the user, the thermostat signals the heating element or burner to shut off.
-
Activation and Deactivation:
- When the water temperature drops below the set point, the thermostat activates the heating element or burner to bring the water temperature back up. This cycle continues as the thermostat ensures the system maintains the desired temperature.
-
Safety Shutdown:
- The thermostat also features safety mechanisms to prevent overheating. If the temperature exceeds a preset limit, the thermostat will trigger a shutdown or cut off the heating element, ensuring that the system does not overheat and cause damage or safety issues.
Applications:
Installation:
-
Turn Off Power:
- Before starting the installation, make sure to turn off power to the water heater or system to avoid electrical hazards.
-
Mounting the Thermostat:
- The ST 12-93K thermostat is designed for surface mounting. Use the mounting screws provided to secure the thermostat to the surface of the appliance in the appropriate location for optimal temperature sensing.
-
Wiring:
- Connect the thermostat according to the wiring diagram provided with the unit. The thermostat typically has three connection points: one for the heating element or burner, one for the power source, and one for the control signal.
-
Adjust Temperature Settings:
- Once installed, set the desired temperature using the thermostat's control dial. Make sure to set the temperature to a safe level for the system to prevent overheating.
-
Test Operation:
- After installation, restore power to the system and test the thermostat’s operation. Verify that the system heats the water to the desired temperature and that the thermostat turns off the heating element once the temperature is reached.
-
Check for Leaks:
- Ensure that all connections are secure and that there are no leaks in the system. Check the thermostat for proper operation and adjust the settings if necessary.
