Electronic Temperature Controller RCC 30 for 4-pipe fan-coil units. The controller is equipped with a rotary knob for setting the desired temperature, a switch, and status LED indicators.

Application

Temperature regulation in rooms heated or cooled by two-pipe fan-coil units.
Two-position valve control and 3-speed fan operation.

The controller is suitable for use in systems with automatic sequence switching between heating/cooling and in systems with continuous operation in heating or cooling sequences.

Function

Using the built-in temperature sensor or via an additional temperature sensor (QAH 11.1), the controller obtains information about the current temperature and ensures temperature regulation to the desired value. Regulation is carried out by 2-position control of the actuator of the regulating valve (open/close).

Operating Modes

Normal Mode - heating or cooling sequence with automatic switching and manually set fan speeds III, II, or I. In this mode, the controller responds to the set desired temperature value.

Frost Protection Mode - if the temperature drops below 8 °C, the controller opens the heating valve and the fan runs at the set speed.

Economy Mode - the heating value in economy mode is 16 °C and the cooling value is 28 °C.
