Single-phase thermostat LF L7102239

A single-phase thermostat regulates the temperature in heated display cabinets and hot cupboards by switching the electrical supply on and off at set intervals. The device senses the ambient temperature and activates the heating element when the air falls below the chosen level, then cuts power once the target is reached. This cycling maintains a steady warmth without overheating, keeping food at a safe serving temperature or preventing condensation in display units.

To use the thermostat, the operator first disconnects the appliance from the power supply. The existing thermostat is removed, and the new unit is fitted in its place, ensuring the wiring connections match the original configuration. Once secured, the appliance is reconnected to the mains. The operator sets the desired temperature on the dial, typically between 30 °C and 85 °C, depending on whether the unit is used for gentle warming or holding hot food. The appliance will then maintain the selected temperature automatically, requiring no further adjustment during operation.

The thermostat is designed as a direct replacement for specific models of ROLLER GRILL display cabinets and VVC 800-10 hot cupboards, as well as AUBERGE, HVC 60 and RELAIS units. It is a single-phase component, meaning it operates on standard mains voltage without requiring a three-phase supply. The temperature range of 30-85 °C allows it to cover both low-temperature holding for delicate items and higher settings for keeping food hot before service.
