Thermal Energy Meter Wmz; General Description; Commissioning; General Information - Dimplex SI 50TE Instructions D'installation Et D'utilisation

ATTENTION!
Ensure that there is a clockwise rotating field: Operating the compressor
in the wrong rotational direction may cause damage to the compressor.
The correct control voltage must be ensured according to the de-
vice information and/or the type plate.
For detailed information, refer to the appendix.

8.3 Thermal energy meter WMZ

8.3.1 General description

The thermal energy meter (WMZ 25/32) is used for measuring
the quantity of thermal energy supplied. It is available as an ac-
cessory. Due to the additional heat exchanger, two thermal en-
ergy meters are required for measuring the quantity of thermal
energy.
Sensors in the flow and return of the heat exchanger pipes and
an electronics module acquire the measured values and transmit
a signal to the heat pump manager, which, depending on the cur-
rent operating mode of the heat pump (heating/DHW/swimming
pool), totals the thermal energy in kWh and displays them in the
operating data and history menu.
NOTE
The thermal energy meter complies with the quality requirements of the
German market incentive programme subsidising efficient heat pumps.
The thermal energy meter is not subject to obligatory calibration, and can
thus not be used for the heating cost billing procedure!
8.3.2 Hydraulic and electrical
integration of the thermal
energy meter
The thermal energy meter requires two measuring devices for
data acquisition.
 A measuring tube for the flow measurement
This must be installed in the heat pump flow (observe flow
direction).
 A temperature sensor (copper pipe with immersion sleeve)
This must be installed in the heat pump return.
The installation locations for both measuring tubes should be as
close to the heat pump as possible in the generator circuit.
To avoid eddying effects which could lead to incorrect measure-
ments, there should be a gap of 50 cm between the measuring
devices and other installed components such as pumps or
valves.

Commissioning

9.1 General Information

To ensure proper commissioning it should be carried out by a
customer service authorised by the manufacturer. This will lead,
under certain circumstances, to an extension of the warranty pe-
riod (cf. Warranty).

9.2 Preparatory Steps

Prior to commissioning, the following items need to be checked:
 All connections of the heat pump must have been made as
described in Chapter 7.
 The heat source system and the heating circuit must have
been filled and checked.
 The strainer must have been fitted in the sole inlet of the
heat pump.
 In the brine and heating circuits all valves that might impair
the proper flow must be open.
 The settings of the heat pump manager must be adapted to
the heating installation in accordance with the instructions
contained in the manager's operating manual.

9.3 Commissioning Procedure

The start-up of the heat pump is effected via the heat pump man-
ager.
ATTENTION!
Commissioning is to be effected in accordance with the installation and
operating manual of the heat pump manager.
