Page 243 ® ABB i-bus Planning and application Control of the room temperature is implemented using a room thermostat, which generally detects the room temperature as well. The device primarily controls a fan and valves. In addition to manual control of the fan via the communication objects Fan speed x, Fan speed switch or Fan speed up/down, the device can also operate in automatic mode together with a room thermostat.
Page 244: Direct Operation
A single-speed, two-speed or three-speed fan can be connected. ® The device sets the fan speed in accordance with a value received via the ABB i-bus . The value is received as a 1 byte value.

Page 251: Pulse Width Modulation (Pwm)
® ABB i-bus Planning and application 4.3.3.2 Pulse width modulation (PWM) With pulse width modulation, the valve is operated as with 2-point control exclusively in the positions fully opened and fully closed. In contrast to a 2-point control, the position is not controlled via limit values, but rather by calculated control values similar to continuous control.
Page 252 ® ABB i-bus Planning and application Example: When the device receives a 1 byte control value (continuous control) as an input signal, this value together with the parameterized cycle time from a PWM calculation is converted into a signal for a 2-point control (ON-OFF-ON).
Page 253: Pulse Width Modulation - Calculation
® ABB i-bus Planning and application Pulse width modulation – calculation 4.3.3.3 With pulse width modulation, control is implemented by a variable mark-space ratio. During the time t the valve is opened and during the time t it is closed.

Important For system reasons, the device switches the outputs OFF for about 1 second after bus voltage recovery, download or ETS reset.
Page 255: Ets Reset
® ABB i-bus Planning and application 4.4.3 ETS reset What is an ETS reset? Generally an ETS reset is defined as a reset of the device via the ETS. The ETS reset is triggered in the ETS under the menu item Commissioning with the function Reset device. This stops and restarts the application.
