6.5.2 Mounting the Outside Temperature Sensor
Note: The temperature sensor (thermistor) is built into the enclosure.
• Take the sensor cover off by unscrewing both screws on the front
cover.
• Use the included screws to attach the base of the sensor to the wall.
• The sensor is wall mounted and the wiring enters through the bottom
of the enclosure. The hole for the cable entry must face downward in
order to prevent water from entering and filling the enclosure.
• The temperature sensor must be mounted in such a way that all
weather conditions are taken into consideration and the measured
value is not falsified.
• Mount on the external wall on the north or north-west side
where possible
• Do not install in a "sheltered position" (e.g. in a wall niche or
under a balcony)
• Not in the vicinity of windows, doors, exhaust air vents,
external lighting or heat pumps
• Not to be exposed to direct sunlight at any time of year
• Above the snow line
• The sensor should be installed at an elevation above the ground that
will prevent accidental damage or tampering.
• Mount the outdoor sensor, loosen the bottom nut, then push the
thermostat/sensor wire through nut and the into each of the terminal
blocks, tighten them down with the screws. Re-tighten the nut. Run
the wiring back to the HydroBox wiring hub, terminals numbers 4 and
5. The connections are not polarity sensitive, so either wire can go to
either terminal.
