UC095
Room unit for VAV controller
FC015
Summary
The UC095 room unit is a communicative human-machine interface for VAV unit
controller FC015.
Application
▪
VAV systems
–
measurement and control of room temperature and CO
2
concentration
Function
The unit reads room temperature and CO
2
concetration in the room air, 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 room controller. The main controller,
FC015, 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 FC015 over a 4 core cable, the most suitable types are JY(St)Y
or LAM 2x2x0.8. Use the same type which powers the FC015 controller as if the room
unit power is taken from the FC015 terminals, the cores in a terminal should be of the
same cross-section.
