Follow the installation instructions supplied with the thermostat
and/or the limiter.
Use a proper wiring diagram for the heating cable layout and
control method desired.
The limiter must be set to ensure that the maximum temperature
of the surface of the cable does not exceed either T-class or
maximum working temperature of the heater for a given output
under worse case conditions.
Warning
as with any temperature measurement equipment, possible
falsification of true temperatures due to increased heat
loss caused by the sensor itself might lead to inaccurate
temperature readings or unsafe tripping of safety limiters. The
setpoint might need to be adjusted accordingly.
Contact pentair Thermal management or the supplier of
the limitation device in order to obtain detailed information
concerning offsetting of limitation devices.
5.2 sensor placement:
Temperature control device
The choice of the right location for the controller sensor depends on,
but is not limited to following aspects:
Flow direction of the fluid, best location: downstream.
Impact of heat sinks such as supports etc, best location:
close to heat sink.
Chimney effect on large size vertical pipes, best location:
on the bottom.
Accessibility for maintenance purposes, best location:
at ground level.
Impact of other heat sources, sun etc., best location:
at cold side.
For details please refer to the engineering documentation.
