Application
▪

–
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. Data is transmitted to the room
controller. The main controller, FCR013, 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 FCR013 over a 4 core cable, the most suitable types are JY(St)Y
or LAM 2x2x0.8. Use the same type which powers the FCR013 controller as if the room
unit power is taken from the FCR013 terminals, the cores in a terminal should be of the
same cross-section.
If there is communication failure between UC013 and FCR013, there is a wrench and
alarm bell icon at the UC013 display. Check signal polarity (terminals 3, 4), bus
termination, and correct wiring at the FCR013 side (see FCR013 data sheet).
