Setup and Installation
The Marley M601W thermostat is designed for wall-mount installation. Due to its line voltage operation, professional installation is strongly recommended.
Installation Steps (Professional Installation Recommended):
- Power Disconnection: Turn off power to the heating circuit at the main electrical panel before beginning installation. Verify power is off using a voltage tester.
- Mounting Location: Select an indoor wall location away from drafts, direct sunlight, or heat-emitting appliances that could affect temperature readings.
- Wiring: Connect the thermostat's wires to the appropriate line voltage and heater wires. Refer to the wiring diagram provided with the product packaging for specific connections. Ensure all connections are tight and secure. This thermostat is designed for 277 Volt systems.
- Mounting: Secure the thermostat to the wall using the provided mounting screws.
- Power Restoration: Once installation is complete and all connections are verified, restore power at the main electrical panel.
Operating Instructions
The Marley M601W thermostat features simple manual operation via a rotary dial.
- Temperature Adjustment: Rotate the central dial clockwise to increase the desired temperature setting and counter-clockwise to decrease it. The temperature range is from 45°F to 75°F.
- OFF Setting: To turn off the heating system, rotate the dial completely counter-clockwise to the "OFF" position.
- Temperature Differential: The thermostat operates with a 4°F differential. This means the heater will turn on when the room temperature drops approximately 2°F below your set point and turn off when it rises approximately 2°F above your set point.
Maintenance
The Marley M601W thermostat requires minimal maintenance.
- Cleaning: Periodically wipe the exterior of the thermostat with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Internal Components: There are no user-serviceable parts inside the thermostat. Do not attempt to open or repair the unit. Refer all servicing to qualified personnel.
- Airflow: Ensure that the vents on the thermostat casing are not obstructed, as this can affect temperature sensing accuracy.
