Theben Mix Series User manual

Heater actuators - Series
HMG 4
HME 4
The heater actuators for the series are as follows:
•BMG 4 (4-chanel basic module) and
•HME 4 (4-channel upgrademodule)
for controlling the heating valves via silent triac outputs.
The heater actuators are suitable for use with the European Installation -
Bus EIB in combination with the tproduct database. ETS
(EIB Tool Software) enables application programs to be selected, and spe-
cific parameters and addresses to be assigned and transferred to the
device.
A type BCU 2.1 bus coupling is integrated into the basic modules. A basic
module can be expanded simply by adding up to 2 upgrade modules.
Any combination of -series modules is possible, e.g.
HMG 4 + HME 4 + HME 4 (12 x heating)
HMG 4 S + RME 4 S + RME 4 S (4 x heating + 8 x
switching)
RMG 4 C-Last + DME 2 + HME 2 (4 x C-load + 2 x dimming
+ 4 x heating)
etc.
1.0 Designated use
The bus line must be routed, connected and installed in accordance with
the valid regulations to DIN-VDE and also the EIB Handbook and ZVEI/
ZVEH. The work may be carried out only by trained electricians qualified
to EIB.
Compliance with the national regulations and valid safety requirementsis
required. Tampering with or making modifications to the
device will invalidate the warranty.
Please note:
• It is permitted to connect different phases in one device.
• It is possible to connect contactable protective low voltage, if all 4
channels of a module switch protective low voltage.
• Switching protectors can be activated for controlling electric heaters,
for example.

HMG 4 Basic device
•The device controls thermal actuators via silent and
non-wearing triac outputs.
•The heating output can be continuously adjusted
as and when required. This is achieved by converting a continuous
control variable into a PWM (pulse width modulation) output signal.
Example:
HME 4 Upgrade module
Manual selector switch permanently - ON / OFF – Bus
operation
Manual switch in position:
The status of the triac is determined by the bus
messages.
The triac is permanently switched on.
The triac is permanently switched off.
Please note: Manual switching can also be used in the event
of a bus voltage failure.

6.0 Technical data
Open the slide on the right-hand side of the module.
Lock the module onto the distributing bus bar.
Push the modules fully together.
Connection:
Ensure correct polarity of the bus connection terminal.
Close the actuator as shown on the wiring diagram
in Chapter 3.0.
The bus is connected to the basic module.

The device is suitable for use in conditions with a normal level of polluti-
on. Observe deviating technical data on the device rating plate! Technical
changes reserved. The devices comply with European Directives 73/23/EEC
(low-voltage directive) and 89/336/EEC (EMC Directive).
If the devices are combined with others for use within a system, ensure
that the system as a whole does not cause radio interference.

Information in the event of bus failure
• If a mains supply is available, the triacs can be operated using the
manual switches should the bus fail.
• The behaviour after bus failure can be set via the application,
e.g. emergency mode.
4.0 Bus connection / (mains) power failure
Information in the event of power failure
If the mains power should fail, all triacs switch-off, irrespective of the
software configuration. This means that the power circuit is
interrupted.
