5. Operation

The iO HVAC Controls TS-55 thermostat is designed for simple, fixed-temperature operation. It is a non-adjustable unit, meaning there are no user controls or display to change the temperature setting.

• Fixed Temperature: The thermostat is factory-preset to maintain a heating temperature of 55°F (approximately 13°C).
• Automatic Operation: When the ambient temperature in the room falls below 55°F, the thermostat will automatically activate the heating system.
• Heating Cycle: The heating system will continue to operate until the ambient temperature rises above 55°F, at which point the thermostat will turn off the heating.
• No User Interface: There are no buttons, switches, or screens for user interaction. Its function is entirely automatic based on the fixed temperature setpoint.

6. Maintenance

The TS-55 thermostat requires minimal maintenance to ensure optimal performance.

• Cleaning: Periodically wipe the exterior of the thermostat with a soft, dry cloth to remove dust. Do not use liquid cleaners or abrasive materials.
• Airflow: Ensure that the thermostat's vents (if any) are not obstructed by dust or debris, as this can affect temperature sensing accuracy.
• No Internal Servicing: The thermostat contains no user-serviceable parts. Do not attempt to open the unit beyond removing the front cover for installation.
