    ABB i-bus® KNX PLANNING AND APPLICATION Note The basic load is activated for all stages, but it applies only to the active operating mode ( Heating Cooling ). The basic load remains active during the operating mode change. The basic load is set individually for each stage in the corresponding parameter windows → Parameter Min.

    The actual value is sent to the input or output when the block is canceled. If the input or output has not received any telegrams via the bus (ABB i-bus® KNX) while a block is active, the input or output will assume the state it was in before the block.

    This adaptation permits exact correction of the room temperature to the setpoint. The control value is sent as a 1-byte value (0 … 100 %) on the bus (ABB i-bus® KNX). To reduce the bus load, the con- trol value is sent only if it has changed by a previously specified value.
  • Page 182 ABB i-bus® KNX PLANNING AND APPLICATION Using hysteresis A 2-point controller can quickly correct large control deviations in the command variable (setpoint tem- perature). As correction is a continuous process, overshooting of the system can occur (exceeding the setpoint temperature). Each 2-point controller features built-in hysteresis to avoid overshooting.

Unlike the procedure for a continuous controller, the control value is converted to a 1-bit PWM switch-on/switch-off ratio prior to output for a PI controller (PWM).

    12.2.14 Sending and switching delay No telegrams are sent on the bus during the sending and switching delay (ABB i-bus® KNX). Telegrams received (e.g. requests from a visualization system) are sent to the outputs after the sending and switching delay expires. The state of the outputs is set according to the settings in the ETS applica- tion or the telegram values of the group objects.

    ABB i-bus® KNX PLANNING AND APPLICATION Fig. 31: Dynamic setpoint adjustment Above the starting temperature, the setpoint temperature is increased according to the selected values until the selected ending temperature is reached. When the ending temperature is reached, the differ- ence between room temperature and outdoor temperature corresponds to the selected offset when summer compensation ends.

    ABB i-bus® KNX PLANNING AND APPLICATION Analog (proportional) valve drives The valve positions between 0 % and 100 % are adopted using a motor in analog (proportional) valve drives. Analog (proportional) valve drives are controlled via a 0-10 V signal. The power for the valve drive is normally supplied via 230 V AC or 24 V AC/DC.

    The device counts the number of telegrams sent within the parameterized period. As soon as the maxi- mum number of sent telegrams is reached, no further telegrams are sent on the bus (ABB i-bus® KNX) until the end of the period. A new period commences automatically at the end of the previous period.

  • Page 192: Forced Operation

    Forced operation is triggered by the switching of a 1- or 2-bit group object. The controller continues to send the control values on the bus (ABB i-bus® KNX) during forced operation. Master/slave communication occurs despite active forced operation.

  • Page 193: Cyclical Monitoring

    ABB i-bus® KNX PLANNING AND APPLICATION Note The same forced operation state as for bus voltage failure applies after bus voltage recovery. Forced operation is deactivated on an ETS reset. Forced operation, 1-bit A state that is set if forced operation is activated can be parameterized with 1-bit forced operation. It can additionally be defined whether activation is to take place via the value 1 or 0.
