Description

Controls a 3 or 5-step fan. Immediate or stepped switching of fan speed is possible.

Safe switching with programmable switch-over delay is realised.

The unused outputs can be used for control of a valve for switching of electrical loads. Here the 2-, 3- or 4-wire fan coil systems with heating and/or cooling circuits, can be controlled via the ABB i-bus EIB / KNX.

Separate objects are available for the valve control so that control is possible via an electronic switch actuator or a higher power switch actuator depending on the requirements. Enhanced comfort with 4 operating modes frost / heat protection, night time operating, comfort and standby mode can be set for the fan and valve.

The following functions are possible with just a single application program:

- 3-step Blower control plus 5 valves or switch outputs

- A 5-step Blower plus 3 valves or switch outputs

- Two independent 3-step Blower controls plus 2 valves

or switch outputs

- Control of 2-wire fan coil systems with 3- or 5-step Blower

- Control of 3-wire fan coil systems with 3- or 5-step Blower

- Control of 4-wire fan coil systems with 3- or 5-step Blower

The following objects are available in the EIB / KNX as control values

- Three 1-bit objects for manual control of the Blower

- One 1-bit object for manual up/down control switching of a Blower step

- One or two 1-byte objects for heating and/or cooling control values
