TAC 2112, Manual Installation
TAC AB, 1999-08-01 0-004-7459-3 (GB), 5:5(10)
Outdoor temperature sensor, EGU
Mount the sensor to an exterior wall facing north or north-west. Place
it approximately 3 m above ground with the cable entry facing down.
If several TAC 2000 are to be used in the same building, it may be
sufficient to mount only one outdoor temperature sensor. A controller
which has no outdoor temperature sensor of its own can then receive
outdoor sensor signals from the controller which has one.
Supply temperature sensor, EGWS, EGA
The immersion sensor EGWS should be mounted in the supply pipe
0.5–1 m after the heat exchanger or the shunt valve. If a strapped-on
sensor EGA is used, this should be mounted onto an uninsulated part
of the supply pipe. Clean the pipe thoroughly so that the copper
sensor plate makes good contact. EGA should not be used on pipes
where Ø > 50 mm (2").
Room temperature sensor, EGRL
The sections of a building which are most affected by changes in
climate should be those in which there is most possibility to influence
the supply temperature. It is also important to ensure that the sensor is
not affected by irrelevant factors. The following should therefore be
considered when fitting:
•
Place the sensor in a north-facing apartment which has more than
one exterior wall (a corner apartment).
•
Install the sensor in the most representative room.
•
Place the sensor on an interior wall made of a light building
material. Avoid stone or concrete. The wall must not be heated
by an underlying heater pipe.
•
The room should be of sufficient size for the temperature not to
be affected by heat from people or machines.
•
The radiators in the room should not have thermostat valves. If
they do, set them to their maximum values.
•
Position the sensor so that air can flow freely around it.
•
Place the reference sensor no more than 10 m from the nearest
radiator, but not directly above it. This is particularly important
in rooms which do not have mechanical ventilation.
Return temperature sensor, EGWS, EGA
The immersion sensor EGWS should be mounted in the return pipe. If
a strapped-on sensor EGA is used, this should be mounted to an
uninsulated part of the pipe. Clean the pipe thoroughly so that the
copper sensor plate makes good contact.
Actuators M5, M15, M42, M44, M500, M750
Assembly instructions are supplied with the actuators and assembly
kits.
