Mounting
Location Considerations
Locate the TE730 Series Temperature Sensor:
•
on a partitioning wall, approximately 1.5 m (5 ft)
above the floor in a location of average
temperature
•
away from direct sunlight, radiant heat, outside
walls, outside doors, air discharge grills, or
stairwells; and from behind doors
•
away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or
sources of electrical interference
Note:
The temperature sensor is shock and vibration
resistant; however, be careful not to drop the unit or
mount it where it could be exposed to excessive
vibration.
The following ambient operating conditions apply:
•
Temperature: 0 to 40°C (32 to 104°F)
•
Humidity: 10 to 90% Relative Humidity (RH),
noncondensing; 30°C (86°F) maximum dew point
To mount the temperature sensor to the wall:
1.
Use a 1.5 mm (1/16 in.) Allen wrench or
Johnson Controls T-4000-119 Allen-Head
Adjustment Tool to loosen the security screw on
the top of the unit.
2.
Insert a coin into the slot next to the security screw
location, then carefully pry the top edge of the
temperature sensor assembly away from its
mounting base and remove.
3.
Pull out approximately 152 mm (6 in.) of cable from
the wall, and insert the cable through the hole in
the mounting base.
4.
Align the mounting base on the wall, and use the
base as a template to mark the location of the two
mounting holes on the surface.
Note:
Confirm that the mounting base is positioned
with the proper edge up. The mounting base is
positioned properly when the security screw is located
on the top edge of the base.
5.
Secure the mounting base to the wall using the
appropriate mounting hardware (field furnished).
6.
Align the tabs on the bottom edge of the mounting
base with the slots on the bottom edge of the
temperature sensor assembly, and rotate the
assembly onto its mounting base.
7.
Use a 1.5 mm (1/16 in.) Allen wrench or
Johnson Controls T-4000-119 Allen-Head
Adjustment Tool to tighten the security screw and
fasten the temperature sensor assembly to the
mounting base.
Wiring
Keep wires as short as possible to minimize
temperature sensor error. Each 76 m (250 ft) run of
1.0 mm diameter (18 AWG) wire or 15 m (50 ft) of
0.5 mm diameter (24 AWG) wire creates 0.83C°
(1.5F°) of error for a platinum sensor due to wire
resistance. To maintain less than 0.83C° (1.5F°) of
error, hold the total resistance of all temperature sensor
wiring below 3 ohms. When wiring the temperature
sensor, do not run low voltage wiring in the same
conduit as line voltage wiring or other conductors
supplying highly inductive loads.
IMPORTANT:
Do not remove the Printed Circuit
Board (PCB). Removing the PCB voids the product
warranty.
!
CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
MISE EN GARDE : Risque de dégâts
matériels.
Ne pas mettre le système sous tension
avant d'avoir vérifié tous les raccords de
câblage. Des fils formant un court-circuit
ou connectés de façon incorrecte
risquent d'endommager
irrémédiablement l'équipement.
IMPORTANT:
Use copper conductors only. Make
all wiring connections in accordance with local,
national, and regional regulations.
