Fan Coil Type setting is used to define system type for the fan (depends on isntallation):

2-pipe cooling: fan can only cool the area

2-pipe heating: fan can only cool the area

2-pipe heat or cool: fan can cool or heat the area depending on changeover options

4-pipe: fan heats or cools depending if the setpoint is higher or lower then the current temperature

Position yourself in HVAC 1/4 menu

Valve actuator: determines the signal type to control the actuator. Depends on installed equipment. Can be:

On/Off : simple binary signal

PWM: pulse width modulation signal

0-10V: Voltage between 0 and 10V proportional to percentage of open signal

Fan motor type: can be 3 speed or EC motor

Position yourself in HVAC 1/4 menu

ECM voltage: The analog output signal (AO1) for the EC motor can be configured with three parameters:

ECM OFF Voltage: If this value is different from zero volts for the controlled EC motor fan, adjust the ECM OFF voltage to a value that will turn off the ECM fan

ECM Min Speed Voltage: Defines the minimum signal value and the minimum speed of the fan (20 %)

ECM Max Speed Voltage: Defines the maximum signal value and the maximum speed of the fan (100 %)

Use + and - buttons to increase or decrease values

Press value button to enter Keyboard to input ECM value number. ECM values are in range from 0V - 10.0 V

Changeover signal: for 2-pipe heat or cool choose the way system selects it works in heating or cooling mode. It can be: Internal or CBMS

Heating changeover Temp ???

Adjust settings for PI controller for FAN Temp, VAV Temp and VAV Air Quality

Adjust P-band and I-time for each PI controller

P-band determines the speed of change. Higher number = faster change, but more volatile ???

I-time determines the slowness of change. Higher number = slower change, but more accurate with less overshoot ??

Use + and - buttons to increase values by 0.1

Adjust P-band and I-time for each PI controller

P-band determines the speed of change. Higher number = faster change, but more volatile

I-time determines the slowness of change. Higher number = slower change, but more accurate with less overshoot
