2 Overview
2.1 Overview devices
The manual refers to the following devices (Order number respectively written in bold letters):
AKH-0400.01 Heating actuator 4-fold, 2TE, 24 or 230V AC, MRDC
o4 channels for electrothermic valve drives, for the maximum number of
electrothermic valve drives have a look at 6.5 Datasheet, detection of 230V AC
failure, 230V AC/24V AC short circuit detection of connected load
AKH-0800.01 Heating actuator 8-fold, 2TE, 24 or 230V AC, MRDC
o8 channels for electrothermic valve drives, for the maximum number of
electrothermic valve drives have a look at 6.5 Datasheet, detection of 230V AC
failure, 230V AC/24V AC short circuit detection of connected load
Attention: Every actuator can be connected to 230V AC or 24V AC.
A mixture of both voltages forbidden!
2.2 Usage & Areas of use
The heating actuator can be connected to 24V AC or 230V AC, so it allows controlling electrothermic
valve drives with 24V AC or 230V AC. The heating actuator is available at the design of 4-fold or 8-
fold.
Integrated 230V AC failure detection as well as short circuit detection, for both voltage types, at the
load allows a high fail-safety. Additional an emergency mode can be adjusted, which gets active
when the cyclic control value fails.
The actuator can be controlled as well by a 1 Bit object as by a 1 Byte object. As special feature, the
controller contains of an integrated controller, which allows controlling the actuator directly by a
temperature value. The integrated controller contains of the 4 operating modes, comfort, night,
standby, and frost-/heat protection. The setpoints can be adjusted individual for the single operating
modes as well as for the heating and cooling mode.
A limitation of the control value, summer /winter mode as well as a protection of the valves
completes the range of service of the heating actuator.

2.4 Structure & Handling
The heating actuator, here a 4-fold actuator is shown, contains of the standard elements
programming-knob, programming-LED, which shows an active programming mode, and a bus-
connection.
The electrothermic valve drives can be connected by the terminal strip with respecting the circuit
diagrams.
Every single channel contains of a status-LED, which shows an active channel by a slow flashing. The
ratio of on to off corresponds the current control value. A significant faster flashing of the LEDs
shows an active disturbance of this channel.

2.5 Functions
The functions are identical for all channels. According to the hardware specification, the device
contains of up to 8 channels-
The labeling of the channels is in alphabetically consecutive order.
The general settings are the same for all of the channels.
There are 4 possible functions for each channel:
Channel
The channel has no function. So there are not any parameterization options for this channel.
switching (1 Bit)
The channel works with a 1 Bit value for the control value, e.g. from a two-step controller or
a PWM-signal. So the output can only be switched on or off at a change of the 1 Bit Input
signal.
By further options like valve type, activatable blocking objects, activatable emergency mode
and dew point alarm as well as status objects, the channel can be adjusted for the present
valve type.
continuous (1 Byte)
The channel works with 1 Byte value for the control value, e.g. from a PI-controller. The Input
signal is transmitted to the valve by a PWM-controller with adjustable cycle time.
Next to the same parameterization options like the 1 Bit input value, the actuator contains of
limitations for the control value and the flow temperature at the 1 Byte mode.
integrated controller
When a channel is selected as integrated controller, the channel creates an own continuous
control value from an existing temperature value. This continuous control transmitted to the
switching output by a PWM-signal.
Next to the same parameterization options as by the 1 Byte input value, the actuator
contains of a lot additional settings for the controller at the integrated controller mode.

2.6 Channel-LEDs
Every channel contains of a LED, which shows the current state of the channel. Additional to the
status, these LEDs show errors of the channels.
The errors are shown as described below:
only one of the channel-LEDs flashes 7 fast flashig, short rak, 7 fast flashig, …
The belonging channel is at the overload mode or has a short circuit at the output.
At the 230V mode a mains voltage failure can additional be recognized. Because often 4
channels are supplied in common, all 4 channels are flashing.
all channel-LEDs flashing
At the four fold actuator, the first channel must be always connected to a load. At the 8-fold
actuator, additional the fifth channel must be connected to a load. Otherwise the actuator
will switch to the error mode and show this by a flashing off all channel-LEDs.
The normal behavior of the actuator is also shown via these LEDs as described below:
switching mode (1 Bit)
The LED shows the switching behavior of the output. If the 2-step controller sends a 1-signal,
the LED is switched on.
continuous mode (1 Byte)/ integrated controller
The LED operates at the PWM mode with the fixed period of 4s and flashes with the cadence
of the control value. At a control value of 50%, the LED will shine for 2s and will be off for 2s.

3 Communication objects
3.1 Overview
The communication objects are for programming the actuator. The assignment can be done by these
objects.
For every channel, 20 objects are reserved. The communication objects for the single channels have
only influence to the belonging channels. The numbering of the communication objects is standardly
done this way, also if not all of the 20 objects are used or a channel is completely deactivated. So the
channel A has the objects from 0 to 19, the channel B from 20 to 39 and so on.
After the objects for the single channels, the global valid objects are following. These objects can
have influence to all channels. At the 4-fold actuator, these objects start with number 80 and at the
8-fold actuator with the number 160.
3.2 Global Communication objects
The global communication objects are following to the objects of the single channels. According to
the parameterization maximum 6 global objects can be shown. The first two objects, numbers
80/160 and 81/161, are for the switchover of summer/winter mode and for the switchover of
heating/cooling. The two following objects are state objects of the size of 1 Bit. The object 82 sends a
1, if at least one channel is active. The object 83/163 reports an error. The last two objects have the
size of 1 Byte and are for the shifting of the maximum control value or the responding of the current
value. The maximum control value can be adjusted by object 85165; the object 84/164 sends the
current maximum.
The following illustration shows the global communication objects:

The startup delay time defines the time, which elapses between a bus power return or an ETS-
Download and the functional restart of the device.
The setting of the voltage level defines the voltage for the connected thermal drives. This setting
changes only the fault detection, other functions are identical. At the 230V mode, the fault detection
recognizes power failure as well as short circuits. At the 24V mode only short circuits are recognized.
If a fault is detected, a 1-signal is sent by the belonging communication object. Additional, the
channel, which is in the fault mode, reacts with a fast flashing of the belonging channel LED. If the
230V main voltage failures, all 4 channels flash, which are connected to this L-connection.

The heating actuator can be set in a summer or winter mode. The polarity of the switchover object
can be adjusted.
Additional a setting can be made which sets the control value continuous to 0% at the summer
mode. Of course, this setting can only be done if a switchover between heating and cooling is
disabled (have a look at 4.1.3). So the actuator works only at the heating mode.

Table 13: Protection of forse fit
To be sure, that a valves, which was not opened for a long period of time, does not block, the heating
actuator has a protection of forse fit. This protection controls all channels at a fixed period of 6 days
for 5 min and drives the valves once completely open.
So, a smooth operation of the valves can be secured.

which you can see at the chart below. The maximum control value is only sent at a change or at a
change and additional cyclically every 30min.
This function allows heatig’s, which can modulate their power, if only less power is required. The
object for the output (Number 84/164) sends the maximum used value at the heating actuator of the
enabled channels. Afterwards this output signal can be analyzed and send the used power to the
heating.
If more than one heating actuator is used, which get all their heating power from one heating, the
objects can be connected by the additional object of the input (Number 85/165). Therefore, the
output of the first actuator has to be connected to the input of the second actuator and so on. Now
the output object of the last actuator sends the maximum used power from all enabled channels of
the connected actuators.
