depending on selected scheme
17.2.4. Temperature sensor installation
Temperature sensors are equipped with
brass coat with diameter of 6mm and 50mm
long. They should be installed possibly close to
the temperature measurement point. The sensors
must be installed so that the brass coat is
thermally insulated from the environment.
The collector temperature sensor must be
located in the collector tube possibly deep, as
this is conditional for correct measurement.
If you need mount your sensor on pipe surface
(e.g. CH temp. measurement), then the sensor
coat must be attached using a brace,
and the jointing point to insulate e.g. with foam
or other insulating material, so that there is
sufficient temperature convection to the sensor.

17.2.5. Output H connection
Output H is adapted to connect relay supplied
with voltage of 5…6V
(with coil resistance not lower than 60Ω)
and power up to 0.5W.
Heater
For a heater connection, use relay
connected as shown in Fig. 17.10. Wire that
connects the controller and transmitter must not
have resistance bigger than 1Ω (see Table of wire
lengths and resistances in the section on wire
length compensation 20.2.1).
The reservoir heater must be connected
through a relay with maximal contact current not
lower than the heater’s nominal current.
Recommended
relay type is Finder
44.62.7.006.0000 that has load ability of
2x10A . It is suitable for heater control
(resistance loads) with power up to 2.5k VA. The
relay together with a base is available as
accessories. If you choose to use other relay,
check its technical parameters and if it meets
safety standards.
Current received by a receiver may not
be higher than nominal current of the
relay load. Otherwise, it may be
damaged and in extreme case it may
cause damage to solar or heating
system.
