In order to prevent heat transmitted through the
wall from affecting the sensor reading, it may be
necessary to install an insulating barrier behind
the enclosure.

The 070 should be mounted on a wall which best
represents the heat load on the building (a
northern wall for most buildings or a southern
facing wall for buildings with large south facing
glass areas).  The 070 should not be exposed to
heat sources such as ventilation or window
openings.

The 070 should be installed at an elevation above
the ground that will prevent accidental damage or
tampering.

Water Temperature Sensor 071

The Water Temperature 071 Sensor has a zinc sleeve
for fast response and a wide operating range (Fig 6D).

Note:  The 071 sensor is designed to mount on a pipe
or in a temperature immersion well.

The 071 sensor can be strapped directly to the
pipe using the cable tie provided.  Insulation
should be placed around the sensor to reduce the
effect of air currents on the sensor measurement
(Fig. 6E).

The 071 sensor should be placed downstream of
a pump or after an elbow or similar fitting.  This is
especially important if large diameter pipes are
used as the thermal stratification within the pipe
can result in erroneous sensor readings.  Proper
