Operating Instructions For Users - Dimplex ZWU 06E Installation And Operating Instructions Manual

Operating instructions for users

General notes
For installation, operation and maintenance, please observe these
installation and operating instructions. This unit should only be installed
and repaired by a qualified technician. Repairs which are improperly
carried out can significantly endanger the safety of the user. In
compliance with the regulations of the VDE (German electrical
engineering association), the installation and operating instructions must
always be available and should be given to the technician working on the
device for their information. We therefore request that these installation
and usage instructions be passed on to the new tenant or owner should
there be a change in occupancy.
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 off-peak periods.
Utility companies offer electricity at discounted tariffs, with priority given
to 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 requirements can vary. Information can be obtained
from your authorised electrician or local utility company.
The specified charging periods are generally released via a control
device (ripple control receiver or timer) by the utility company. The ZWU
06E central control unit ensures the consumption-based charging of your
storage heating system.
To ensure the utility company's technical connection requirements are
met, your electrician will carry out the precise setting of all required
values on the central control unit and if necessary on the charge
controllers.

Central control and charge controller
The ZWU 06E central control unit measures the weather conditions,
together with the building's inertia, via the external sensor located in the
brickwork.
This reference variable is connected, with the various settings and the
runtime, and depending on the signals of the control terminals, to the
central control unit's output variable (set charge rate = control voltage).
The control voltage is transferred to the electronic charge controller,
which functions as the ON/OFF controller.
For underfloor storage heating systems, the controller set point is
determined by the amount of applied control voltage and position of the
intensity actuator "daytime" or "night-time" on the charge controller. The
actual value of charging for any heating circuit is reported to the charge
controller via the residual heat sensor in the insulating screed.
For storage heaters, the control set point depends on the applied control
voltage and the configured charge intensity.
The actual value of charging is determined via the residual heat sensor
by measuring the core temperature. The charge controller compares the
set point with the actual value and, if necessary, switches on the
charging until the required heat content is reached.
Setting the charge controller of an underfloor heater
Night-time charging and daytime charging can be corrected for each
heating circuit via the charge controller. Night-time charging affects the
room temperature during the early morning and late morning, whereas
the daytime charging affects the room temperature in the afternoon.
Setting information can be found in the corresponding operating manual.
