RCC30
for four-pipe fan coil units
Outputs for on / off valve actuators
Outputs for three-speed fan
Control depending on room or return air temperature
Operating modes: normal, energy saving and frost protection or OFF
Operating mode changeover input for remote control
Selectable control parameters
Operating voltage AC 230 V
Use
Typical use:
∂ Control of the room temperature in individual rooms that are heated or cooled with
four-pipe fan coil units.
∂ For opening or closing a valve
∂ for switching a three-speed fan.
Functions
The controller acquires the room temperature with its integrated sensor or external
room temperature sensor (QAA32) or external return air temperature sensor (QAH11.1)
- if used - and maintains the setpoint by delivering control commands to the 2-point-
valve.
The switching differential is adjustable. It can be 1 or 4 K in heating mode and
0.5 or 2 K in cooling mode.
