- SPDT Contacts: Single Pole Double Throw contacts allow for both heating and cooling applications.
- Broad Temperature Range: Suitable for diverse environmental control needs.
- Dust-Protected Enclosure: Enhances durability and reliability in various settings.
- Mechanical Knob Control: Simple and direct temperature adjustment.
4. Installation
IMPORTANT: All wiring must conform to local and national electrical codes. Installation should only be performed by a qualified electrician.
4.1 Mounting Location
- Mount the thermostat on a flat, vertical surface, away from direct sunlight, drafts, or heat sources that could affect temperature readings.
- Ensure the location allows for proper air circulation around the sensor coil.
- The thermostat should be mounted at a height of approximately 5 feet (1.5 meters) from the floor for optimal performance.
4.2 Wiring
- Disconnect Power: Before beginning any wiring, ensure that power to the circuit is completely disconnected at the main service panel.
- Remove Cover: Carefully remove the front cover of the thermostat to access the wiring terminals.
- Connect Wires: Connect the line voltage wires to the appropriate terminals as indicated by the wiring diagram provided with the product packaging. The SPDT contacts allow for configuration as either a heating or cooling control. Refer to the specific wiring diagram for your application (heating or cooling).
- Secure Wiring: Ensure all wire connections are tight and secure. Use appropriate wire nuts or connectors.
- Replace Cover: Once wiring is complete and verified, carefully replace the front cover.
- Restore Power: Restore power at the main service panel.
Note: A detailed wiring diagram is typically included with the product packaging. If you do not have this diagram, consult a qualified electrician or contact Dayton customer support.
5. Setup and Operation
The Dayton 6EDY5 thermostat is designed for straightforward operation using its mechanical temperature adjustment knob.
5.1 Setting the Temperature
- Locate the rotary dial on the front of the thermostat.
- Turn the dial clockwise or counter-clockwise to align the desired temperature setting with the indicator mark.
- The thermostat will activate or deactivate the connected HVAC system to maintain the set temperature.
5.2 Heating vs. Cooling Application
The 6EDY5 thermostat can be configured for either heating or cooling applications by adjusting the internal wiring connections. This configuration is typically done during installation. For heating, the thermostat will close contacts when the temperature falls below the set point. For cooling, it will close contacts when the temperature rises above the set point. Refer to the installation wiring diagram for specific instructions on configuring for heating or cooling modes.
6. Maintenance
The Dayton 6EDY5 Line Voltage Thermostat requires minimal maintenance to ensure continued reliable operation.
- Cleaning: Periodically wipe the exterior of the thermostat with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the internal components.
- Sensor Area: Keep the area around the exposed sensor coil free from dust and obstructions to ensure accurate temperature readings.
- No User-Serviceable Parts: There are no user-serviceable parts inside the thermostat. Do not attempt to disassemble the unit beyond removing the front cover for wiring access.
7. Troubleshooting
If your Dayton 6EDY5 thermostat is not functioning as expected, review the following common issues before contacting support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat not turning system ON/OFF. | No power to the thermostat or HVAC system. Incorrect wiring. | Check circuit breaker/fuse. Verify all wiring connections are secure and correct (consult wiring diagram). |
| Inaccurate temperature readings. | Thermostat located near heat sources, drafts, or obstructions. Sensor coil is dirty or obstructed. | Relocate thermostat if possible. Ensure sensor area is clean and clear. |
| System runs continuously or not at all. | Incorrect thermostat setting. Wiring error (e.g., configured for heating when cooling is needed, or vice-versa). | Adjust temperature setting. Verify thermostat is correctly wired for the intended application (heating or cooling). |
If troubleshooting steps do not resolve the issue, contact a qualified electrician or Dayton customer support for assistance.
