Room temperature controller RCC 20 for two-pipe fan coil units with electric heating. The regulator
is equipped with a knob for setting the desired temperature, a switch and status LEDs.

Usage

  • Room temperature control in rooms heated or cooled by two-pipe fan coil units.
  • Two-position valve control and 3-turn fan control.
  • Switching electric heating on/off.

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

Function

By means of the built-in temperature sensor or via an additional temperature sensor (QAH 11.1), the regulator
acquires the current temperature information and ensures the temperature control to the setpoint. The control takes place via 2-position control of the regulator valve actuator (open/closed).

Operating modes

Fan operation - controlled by output Q1, Q2 or Q3 according to the selected stage. In case of overheating by the electric heating, the fan continues to run for 30s after switching off the heating (fan LED flashes).

Heating/cooling operation - opening or closing the heating or cooling valve when the set point decreases or increases.

Extraction temperature - The RCC 20 can regulate either the measured room temperature or the fan coil extraction temperature. The changeover occurs when the QAH 11.1 cable temperature sensor is connected.

Automatic changeover - external sensor QAH 11.1 + ARG 86.3 (changeover) senses the water temperature and automatically selects the heating or cooling mode according to the measured value.

Normal operation - heating or cooling sequence with automatic changeover and manually set fan speed III, II or I. In this mode, the controller reacts to the set temperature setpoint.

Frost protection mode - when the temperature drops below 8 °C, the controller opens the heating valve and the fan runs at the set speed.

Power saving mode - the value of heating in power saving mode is 16 °C and the value for cooling is 28 °C.
