3.2 Irradiation sensor
The V40 is a measuring instrument with contact donator for
recording the flow of water or water/glycol mixtures and
is used in combination with the calorimeter integrated into
the BW/H Komfort After flow of a specific volume, the V40
sends an impulse to the calorimeter. The used heat amount
is measured by these impulses and a measured temperature
difference with the help of pre-defined parameters (glycol
type, concentration, heat cpacity, etc.).

3. Sensors
3.1 Temperature sensors
Precision-platin sensors type PT1000 (FKP and FRP) are
used for the controller BW/H Komfort.
Depending on the individual solar system, the product range
contains 3 different sensor types: sensors with immersion
sleeves, flatscrew sensors and cylindrical clip-on sensors. The
sensor types FK and FR have the same electrical features
and are available in the same models, they only differ in the
connecting cable:
FK: 1,5 m weather- and temperature resistant silicone cable
for temperatures between -50 °C ... +180 °C, mostly used
for collectors.
FR: 2,5 m PVC cable for temperatures between
-5 °C ... +80 °C, mostly used for stores.
Make sure that all electrical works are carried out accor-
ding to the relevant local and IEE-regulations. The sensor
cables carry low voltages and they must not run together
in a cable conduit with cables carrying higher voltages than
50 Volts. When using longer cables or cable conduits, please
use screened cables. The sensor cables can be lengthened up
to 100 m, but the cross section must be 1,5 mm² (or 0,75
mm² up to a cable length of 50 m); screened cables should be
used preferably. The sensors must not be in direct contact
with water, please always use immersion sleeves.
The remote control RTA11 allows a comfortable adjustment
of the heating curve of the controller from the living room.
The rise of the heating curve causes an increase in flow
temperature, a fall causes a decrease. The remote control
additionnally contains the functions „heating circuit-off“ and
„fast heating-up“.
Note:
In order to avoid overvoltage damages at collector sensors
(e.g. from local lightning storms), we recommend to install
the overvoltage protection
SP1
.
3.4 Remote control
The solar cell is used for recording of the momentary
irradiation intensity. The short-circuit flow rises with the
increase of irradiation intensity. The relation between the
short-circuit flow and the irradiation intensity is directly
proportional. The connecting cord can be expanded up to
100 m.
