• Avoid using rechargeable batteries. (Rechargeable batteries cannot maintain
correct power requirements).
• Insert batteries before first use, matching the polarity in the battery compartment
• During an initial setup, place the main unit close to the remote UV sensor.
• After reception is established (the remote UV readings will appear on the main
unit’s display), position the UV sensor and the main unit within the effective
transmission range of 328 feet (100 meters). Ideally it should be placed within
the line of sight of the main unit.
• Transmission range may be affected by trees, metal structures and electronic
appliances.
• The effective operating range may be influenced by the surrounding building
materials and how the receiver (main unit) and transmitter (UV sensor) are
positioned.
• Place the remote UV sensor so that it faces the main unit (receiver), minimizing
obstructions such as doors, walls and furniture.
Installation
The Honeywell Remote UV sensor TS704 operates at 433MHz radio frequency, so no
wire installation is required between the main unit (receiver) and the remote UV sensor
(transmitter).
All data measured by the remote UV sensor is transmitted to the main unit wirelessly,
with the operating range of 328 feet (100 meters) in the open area.
Remote UV sensor must be placed outdoors to measure ultraviolet light levels.
To install it:
• Unscrew the lid on top of the UV sensor unit.
• Remove the screw from the battery compartment door with a small Phillips
screwdriver.
• Insert two 2 “AA” size 1.5V batteries (not included) matching the polarities
shown in the battery compartment.
• Replace the battery compartment door and secure the screw. The red light from
the LED indicator will flash once meaning the UV sensor works properly.
• Screw the UV sensor unit lid back.
• Press DOWN button either on the main unit control panel or handheld remote
control. The UV reading (usually 0.00) will appear in UV window of TE923W main
unit display, instead of “ - - -“.
Assembly
• Snap the U-shaped sensor holder onto the UV sensor unit side grooves.
• Insert the round end of the U-shaped holder into the one of the mounting
hardware pieces provided (ground, stake or wall).
