Betet Electronics RCC30 Room Temperature Controller Manual
The RCC30 is a room temperature controller for four‑pipe fan coil units. It can operate in heating and cooling modes, provides switch‑type outputs for valve actuators and three‑speed fans, and supports remote mode switching and adjustable control parameters.
The manual covers installation, wiring diagrams, DIP switch settings, technical specifications, and safety certifications, guiding users through proper mounting, connection, and configuration of the controller. This manual is written in Chinese.

Questions answered in these manuals
What temperature range can be set on the RCC30?
The settable temperature range is from 8 °C to 30 °C.
From: Betet Electronics RCC30 Room Temperature Controller Manual
How does the RCC30 control heating and cooling valves?
The controller uses output Y11 to open the heating valve when the room temperature falls below the setpoint by half the conversion error and the valve has been fully closed for more than one minute; it closes the valve when the temperature rises above the setpoint by the same margin. The same logic applies to the cooling valve using Y11 (or Y21) with opposite commands.

How is fan speed controlled on the RCC30?
Fan speed is controlled by the three outputs Q1, Q2 and Q3. When the “control fan by temperature” function is selected, the fan speed follows the temperature setpoint and operates synchronously with the valve; otherwise it can be set manually.
