Salus WT100 - Connection of Temperature Sensors; Connecting Weather Sensor (External)

Connection of temperature sensors
Use only following sensor types: CT10, CT6-P.
The use of other sensors is prohibited.
Sensors cables could be extended by a cable
with cross-sectional area min. 0,5mm
2
, a total
cable length max. 15m.
Boiler temperature sensor should be installed
in thermostatic pipe installed in boiler. Mixer
temperature sensor should be installed in
sleeve located in stream of running water in
pipe, but also it can be installed on the pipe,
on condition that it is thermo isolated from the
environment.
Mounting temperature sensor: 1 - pipe, 2 – clamps,
3 - thermal insulation, 4 - temperature sensor.
Sensor must be protected from
getting loose from the surfaces to
which they are connected.
Good thermo contact should be maintained
between sensors and measured surface. To
this purpose thermoleading paste should be
used. It is not acceptable to lubricate sensors
with water or oil. Wires of sensors should be
separated from network electrical wires. In
such a case wrong readings of temperature
may be shown. Minimum length between
those wires should be 100mm. It is not
acceptable to allow for contact betweens wires
of the sensors and hot parts of the boiler and
heating installation. Wires of the sensors are
resistant to temperature not exceeding
100ºC.
From the regulator can also be formed to
correct an error reading from temperature
sensors: circuit heating, external, return and
boiler to the nearest 0,1°C.

Connecting weather sensor
(external)
The regulator cooperates only with a weather
sensor of the CT6-P type. The sensor should
be installed on the coldest wall of the building,
usually this is the northern wall, under a roof.
The sensor should not be exposed to direct
sunlight and rain. The sensor should be fitted
at least 2m above the ground, far from
windows, chimneys and other heat sources
which could disturb the temperature
measurement (at least 1,5m).
Connect the sensor using cable of 0,5mm
2
cross-section, up to 25m long. Polarity of the
leads is insignificant. Connect the other end of
the cable to the regulator.
Attach the sensor to the wall using tackbolts.
To access the tackbolts holes, unscrew the
sensor lid.
