RCF-230D
RCF-230D
Room thermostat for fan-coil applications
with on/off outputs
• Supply voltage 230 V AC
• On/off temperature control, 230 V AC outputs
• Built-in relays for a 3-speed fan, 230 V AC
RCF-230D is a room thermostat intended to control
heating and/or cooling in 2- or 4-pipe installations.
Setpoint and fan speed are set using the buttons on the
front.
• Backlit display
• Input for occupancy detector or window contact
• Input for automatic change-over cooling/heating
RCF-230D is a thermostat for controlling heating and/
or cooling in a room using on/off outputs. It also has a
function for three-speed fan control (for fan-coil).
The thermostat has supply voltage 230 V AC. It has triac
outputs for 230 V AC heating/cooling and built-in
230 V AC fan relays, which means that a separate relay
module is not required for the fan and actuators.
Applications
The thermostat is suitable in buildings where you want
optimal comfort and reduced energy consumption, for
example offices, schools, shopping centres, airports, hotels
and hospitals etc.
Design
The thermostat has a modern design, inspired by the
award-winning design of Regin’s Regio controllers.
Simple installation
The modular design with a separate bottom plate
for wiring makes the thermostat easy to install and
commission. The bottom plate can be put into place
before the electronics are installed. Mounting is directly
on the wall or on a wall socket.
Control function
The thermostat controls heating and/or cooling in a
room via on/off outputs. It has settable hysteresis, factory
setting 1 K (°C). The setpoint can be changed using the
INCREASE ( ) and DECREASE ( ) buttons on the
front.
See also the section ”Display information and handling”
on page 2.
Built-in or external sensor
The thermostat has a built-in sensor. Alternatively, the
input for an external PT1000-sensor can be used.
On/off control outputs
RCF-230D has outputs for controlling 230 V AC on/off
actuators or similar.
2- and 4-pipe installations
In 2-pipe installations, the same water system is used for
heating and cooling, depending on the season. Chilled
water is distributed in the system during summer
and heated water during winter. When RCF-230D is
configured for a 2-pipe system, output DO4 is used for
controlling heating or cooling (depending on the season
(fluid temperature)) via an actuator, a valve or similar
(change-over function).
In 4-pipe installations, there are two separate water
systems for heating and cooling with separate valves. The
thermostat uses two outputs for control of heating and
cooling in sequence.
