Actuator for fan coil units, 0 to 10 V

The Fan Coil Unit Controller is used to control fan coil units, floor heating or switch actuators. Depending on the design of the device, fan coil units are used in 2-pipe or 4-pipe systems. It controls up to 3 fan speeds (Relay or 0-10V outputs) as well as heating or cooling valves (Proportional or electrothermal valve) respectively. The mode of control is based on two-step control or a time-discrete PI controller with setpoint/actual value comparison. The valves and the fan can be regulated directly by devices via the closed loop of this controller. When the Fan Coil Unit Controller is used in floor heating, it can control up to seven channel. All of the floor heating channel control is used a time-discrete PI controller with setpoint / actual value comparison. The following functions can be set in different functions:

1. Five channel 10A relay outputs

2. Two channel 0-10V DC outputs

3. Fan speed: High, Medium, Low 4. HVAC working mode: Heating, Cooling 5. HVAC op. mode: Standby, Comfort, Night, Frost protection

6. Fan speed and Valve status report

7. Seven local temperature sampling

8. BUS temperature sampling

9. Local temperature report .

10.Seven channel floor heating outputs

11.Five control mode each floor heating channel .

12.Seven channel output independently

13.Channel statistics total ON time

14.Channel state response

15.Channel state after bus voltage failure and recovery

16.Staircase light

17.Delay

18.PWM control output
