UC010
Room unit for fancoil controller FCR010
Summary
The UC010 room unit is a communicative human-machine interface for fancoil
controller FCR010.
According to production type, each version of the unit may contain display, backlight
and knob.
UC010 – basic version with display and knob
UC010BL – version with display, knob and backlight
UC010DK – version without knob and display
Application
▪ Fan coil systems – measurement and control of room temperature
Function
The unit reads room temperature, temperature correction / setpoint by a knob, and
required operation mode which is set by a short push or in the menu. Data is
transmitted to the fancoil controller. The fan coil controller may send to the unit other
data (heating / cooling mode, fan stage, day / night / standby mode etc.) which are
displayed on the LCD display.
Connect the room unit to FCR010 over a 4 core cable, the most suitable types are JY(St)Y
or LAM 2x2x0.8. Use the same type which powers the FCR010 controller as if the room
unit power is taken from the FCR010 terminals, the cores in a terminal should be of the
same cross-section.
If there is communication failure between UC010 and FCR010, there is a wrench and
alarm bell icon at the UC010 display. Check signal polarity (terminals 3, 4), bus
termination, and correct wiring at the FCR010 side (see FCR010 data sheet).
