Temperature Controller FF RT-820 230V 16A – single-channel thermostat for heating and cooling control

FF RT-820 is a single-channel temperature controller designed for 230V electrical systems with a 16A switching capacity. The device monitors ambient temperature and activates or deactivates a connected heating or cooling load according to user-defined setpoints. It is suitable for basic temperature regulation tasks where a simple, reliable thermostat is required for electric heaters, ventilation fans, small boilers or refrigeration equipment in residential and light commercial environments.

Advantages

The thermostat provides straightforward single-channel control with a clear setpoint-driven operation, supporting both heating and cooling modes. It offers a robust 16A relay output compatible with typical household and light commercial loads at 230V. The compact design allows for easy mounting and integration into existing installations while minimizing wiring complexity. Temperature monitoring and automatic switching reduce the need for manual intervention and help maintain stable environmental conditions.

Suitable for

• Electric space heaters and convectors
• Ventilation fans and extractor units
• Small domestic or workshop boilers
• Light commercial refrigeration or cooling units
• Basic temperature control in utility rooms, greenhouses or storage areas

Key specifications

• Supply voltage: 230 V AC
• Maximum switching current: 16 A
• Single control channel for heating or cooling
• Temperature sensing and setpoint control capability
• Relay-based on/off switching
• Compact form factor suitable for panel or wall mounting

How to use

Install the controller according to local electrical codes, connecting the mains live and neutral to the supply terminals and wiring the controlled load through the relay output. Configure the device by setting the desired temperature setpoint and selecting heating or cooling mode as required. The thermostat will compare measured temperature to the setpoint and switch the relay to energize or de-energize the connected equipment automatically. Periodically verify sensor placement and wiring integrity to ensure accurate control.

Usage recommendations

Place the temperature sensor away from direct heat sources, drafts and sunlight to ensure accurate readings. Choose wiring and protective devices that match the 230 V/16 A ratings and follow applicable safety standards. For loads with high inrush current or inductive characteristics, consider using an appropriately rated contactor or motor starter to extend the controller’s service life.
