SPECIFICATIONS
GENERAL
The T7416A outside air temperature sensor is used in
heating, ventilating and air conditioning systems for reset of
the main setpoint in weather dependent control systems.
They are designed for wall mounting. The Outside Air
Temperature Sensors are used in the following control
systems
• Excel Classic
• Excel Plus
• High Performance Excel Plus
• Excel EMC
• Excel 5000
• MicroniK 100 and MicroniK 200
or other systems using the specified temperature sensing
elements. The resistor sensing element changes its
resistance value according to the temperature.

INSTALLATION
Wiring Run Maximum Length
Sensor to controller 200m (660ft)
Offset of Pt 1000 sensor due to wire resistance per 10m
distance from sensor to controller; NTC sensor negligible:
Type of Wire Temperature Offset
0.5mm2 (AWG20) 0.18°C (0.324°F)
1.0mm2 (AWG17) 0.09°C (0.162°F)
1.5mm2 (AWG15) 0.06°C (0.108°F)
NOTE: Use shielded wiring in areas with high EMI.
Keep 15cm (5.9’’) minimum distance between sensor
lines and 230Vac power lines.
