6 Consumption Calculation
Due to the radiator exponent is part of the calculation algorithm and thus a basis for calculating of the counting
process of the HCA e2, the following formula is used to calculate the consumption value:
In case of operation with product scale:
In case of operation with unit scale:
1-sensor mode:
���������������������� ���������� = ������������������ ���������� ∗
2-sensor mode:
���������������������� ���������� = ������������������ ���������� ∗
Remote sensor (RS) mode:
���������������������� ���������� = ������������������ ���������� ∗
7 Remote Sensor
The Engelmann heat cost allocator HCA e2 can be equipped with a separately available remote sensor (2 m and 5 m
cable length).
7.1 First installation of the remote sensor
The remote sensor is press-fitted with the contact block on the rear side of the device in
the provided opening in such a way that the contact block rests fully and flat on the plastic
edge of the provided opening. The cable is guided downwards through the housing recess
provided for this purpose. The recess is closed by a predetermined breaking point. This
can be very easily broken out with the thumb or a screwdriver. When installed on the
aluminum heat conductor, the device detects the attached remote sensor and configures accordingly for the remote
sensor mode (see 5.1).
7.2 Retrofitting: remote sensor <= => compact device
The Engelmann heat cost allocator offers a special feature relating to the subsequent modification of the operating
mode. In the case of an Engelmann heating cost allocator, which is already in operation, it is possible to retrofit a
compact device with a remote sensor, as well as retrofit a device with an already connected remote sensor back into
a compact device. The following procedure (VG) must be observed.
