Unit Description
The GR 05 DC group control unit enables individual control
of groups of heaters, for example in a flat that is connected
to a storage heating system in a multiple unit building. The
atmospherically-controlled charge value of the upstream
central control unit is transferred to the group control unit
via a control line.
Scope of Delivery
-
GR 05 DC group control unit
Installation and operating instructions
The specified charge level of the central control unit can be
raised or lowered proportionally via the E5 adjuster.
The desired proportional charge (100 to 0%) can be set via
the KUP (heating curve switching, percent) adjuster
according to the charge rate value when the KU (heating
curve) terminal is activated.

Operating Instructions for Users
General information
For installation, operation and maintenance, please observe
these installation and operating instructions. This unit
should only be installed and repaired by an experienced
technician. Poorly carried out repairs can endanger the
user’s safety. According to VDE (association of German
engineers) regulations, the installation and operating
instructions must always be available and should be given
to the technician working on the unit for his/her information.
Should ownership change, these installation and operating
instructions must be passed on to the new user or owner.

This is how your heating system works
The local utility company makes electricity available for
electrical heating purposes during periods in which other
customers require little or no electricity – the so-called offpeak periods.
Utility companies offer electricity at discounted tariffs
primarily during the night-time release period. In certain
service areas, electricity for heating purposes is additionally
available during the daytime – the so-called additional
release period. For release and additional release periods,
the tariff conditions may vary. Information can be obtained
from your authorised electrician or local utility company.
The specified charging periods are generally released via a
control unit (ripple control receiver or timer) by the utility
company. Charge control ensures the consumption-based
charging of your storage heater.
In order to ensure the utility company’s technical connection
requirements are met, your electrician will carry out the
precise setting of all necessary values on the central control
unit and the charge controllers.
Adjusting the charging on the group control unit
Different user preferences may require correction of the
charging specified by the central control unit, e.g. in a flat
within a multiple unit building. The specified charge value
can be changed via the E5 adjuster.
Attention! Changes will not become apparent until the
following day, after charging has been completed. Only
adjust E5 in small increments.
• Insufficient charging: increase E5 by 5%!
• Excess charging: lower E5 by 5%!
Lowering charge

Setting the intensity actuator (charge selection
button) on a storage heater
For automatic operation, the intensity actuator is set at the
right-hand stop (factory setting), i.e. the storage heater
charges at the value specified by the charge control.
In areas with reduced heating needs, e.g. bedrooms, the
charging of the storage heater can be reduced by turning
the charge selection button to the left. No charging takes
place at the left-hand stop.
In order to prevent operating errors and unintentional resetting, for automatic operation it is recommended that the
controller button be removed from the storage heater’s
intensity actuator and covered with the closing cap.
Should no charging of the storage heater be necessary in
the summer months (even on cooler summer nights), we
recommend taking the entire heating system out of
operation. For more information consult your authorised
electrician. Please observe the technical connection
requirements of your local utility company.

Setting the lowering function
Your technician may install a lowering function (heating
curve switching (KU)). In this case, it is possible to reduce
charging proportionally via a switching contact, e.g. if the
flat is not used for a longer period of time (holidays,
weekend houses etc.).
With the KUP (heating curve switching, percent) adjuster,
the amount of input signal can be set in percent. This
setting affects the level of the reduction.
The factory default is 30%.

Installation and Operating Instructions for Technicians
Installing the central control unit
Electrical connection
Installation should only be carried out by a technician
authorised by the utility company responsible. The
regulations of the local utility company as well as the relevant
VDE (association of German engineers) regulations are to be
observed.
The unit requires 3 DIN 43880 modular spaces. Safety
according to protection class II is ensured via either:
When connecting the GR 05 DC group control unit, please
observe the following:
•
•
•
• Installation in a small distribution board according to DIN
57603/VDE 0603 (e.g. N system distribution board)
The connections at the L and N terminals should not
be interchanged
The KU (heating curve switching) pilot wire must be
connected in phase with L.
Should a phase be connected at a red-marked terminal
due to a mistake in the wiring, the unit will be destroyed.
The group control unit permits connection of:
• Installation in a distribution board according to DIN
57659/VDE 0659.
According to DIN 44574, the group control unit should be
installed in the coolest location, i.e. the lowest mounting row
of the distribution board. Please ensure a clearance of at
least one modular space on both sides.
•
•
100 charge controllers maximum
Control lines must be twin-wire laid according to DIN
44573. According to the VDE directive 0100, these two
wires may not be laid in one cable with network wires.

* Characteristic curve for lower operation: KU (heating curve switching) control and
KUP (heating curve switching, percent) setting = 30%
** Characteristic curve for the factory default of the upstream charge control unit
(E2 = 15 °C, E 15=15% and E1 = -12 °C) and E5 = 0% at the group control unit
Heating curve switching
Heating curve switching is active via a bridge between the KU (heating curve switching) terminal and L (charge).
Depending on the KUP (heating curve switching, percent) setting value, the input charge signal (Z1+/Z2-) is proportionally
reduced to an adjustable level. (KUP (heating curve switching, percent) factory default = 30%). The output charge signal
(A1+/A2-) is adjusted accordingly. With a setting of KUP (heating curve switching, percent) = 0%, the group control unit blocks
charging.
Correcting Basic Settings
Please note that if settings are changed, corrections do not become apparent until the following day.
