Theben HMG 8 Operating Instructions

Operating Instructions for Heating Actuator
Heating actuator HMG 8 and expansion units
Heating modules HME 8 and HMX 4
Switching modules RME 8 and RMX 4
Window contact module FME 8
1.0 Use in accordance with the intended application
The heating actuator of type HMG 8 is suitable for use with the European
Installation bus- in connection with the
fitted with the BCU 2 for the bus communication.
Basic device HMG 8
• 8 heating outputs, each capable of handling up to 10 thermal actuators
Expansion units
• HME 8 8 additional heating outputs
• HMx 4 4 additional heating outputs
• RME 8 8 switching outputs
• RMX 4 4 switching outputs
• FME 8 8 window contact inputs with safety extra low voltage (SELV)
2.0 Electrical connection
Both routing and connecting up the bus cable as well as installation work must be
carried out in accordance with the applicable regulations and guidelines of DIN-
VDE, as well as with the EIB Handbook from ZVEI/ZVEH. The work may only be
carried out by qualified electricians with appropriate EIB training. National norms
and the applicable safety regulations shall be observed. Any changes made to the
device will invalidate the guarantee.
2.1 Network connection
Each module must be connected to a standard main power source.
Connecting the expansion module
Be sure to use the same phase and fused circuit as used for the base module
supply voltage to the logic system (L-, N connections).

standard main power source so that
24 V~ thermal actuators can also
be used.

Behaviour without ETS programming
The connected expansion modules are detected and actuated.
• HME 8 and HMX 4
- Actuator behavior: when switched on, it is in heating mode.
- The output value is 50 %.
- Can be manually operated for testing purposes.
• RME 8 and RMX 4
- Relays stays off.
- Can be manually operated (manual ON/OFF)
• FME 8
- LED status display
• see also section 6.0
3.0 Behaviour during a power or an operational failure
Note concerning power failure
All relays - irrespective of their assigned parameters - drop during a power failure.
This means that the electric circuit is opened.
Note concerning a bus failure only
Provided power is still being supplied the relays can be switched from the device´s
keypad in the event the bus fails.
4.0 Expansion modules
The heating module HMG 8 can be expanded by using max. 1 expansion module.
No new EIB programming is required when replacing a defective device.
Remove the strip of insulation of the right-hand side of the HMG 8
device (fig. 1).
Keep the strip of insulation for further use by attaching underneath the
opening for the plug-in contact.
Snap the modules HMG 8 and the expansion module onto the multi-
terminal rail (fig. 2).
Push the module HMG 8 and the expansion module completely
together (fig. 3).
Connection
Connect up the switch actuator in accordance with the circuit diagram
shown in chapter 2.2.
Removal instructions
When moving the expansion module, always protect the opening of the
remaining actuator HMG 8 by covering with a strip of insulating tape!
