Room temperature controller RCC 30 for four-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.

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

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.
