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
t
product 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 h 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.
