REMKO CMF / CMT
Temperature sensors
External sensor The number of sensors required
can vary with the type of system.
The indoor module contains the
collector sensor, the return sensor
and the sensor for the liquid line.
The scope of delivery contains the
external sensor and immersion
sensor.
When connecting a solar collector,
the PT-1000 sensor has to be used
for measuring the collector tem-
perature! All other sensors have to
be NTC-sensors with a reference
resistance of 5 kilo Ohms.
All sensors are to be connected
to the indoor module switching
cabinet in accordance with the
terminal assignment diagram.
The connection of an outdoor sen-
sor is always required for the heat
pump manager.
■ The outdoor sensor is to be
mounted in a north-easterly
direction approx. 2.5 metres
above the ground. It may not
be subjected to direct sunlight
and is to be protected against
excessive wind. Installation
above windows or air ducts is
to be avoided.
■ In order to carry out installa-
tion, the cover is to be removed
and the sensor is to be fastened
with the screws included.
■
A cable with wire diameters of
1.0 mm² is recommended for
connecting the sensor.
Contact sensor
Contact sensors can be mounted
on the pipes in order to measure
e.g. the heating circuit tempera-
tures.
■ The contact sensors are fi xed
in position with the enclosed
trapezoidal brackets and the
retaining strap is fi xed to a pipe.
■ The corresponding site must be
cleaned. Subsequently a ther-
mal compound (A) is applied
and the sensor is fi xed in posi-
tion.
In the event of insuffi cient cable
length, the sensor cables can
be extended up to a maximum
of 100 m with 1.5 m² diameter
wire.
