Parameter Set
1) Normal display status: display current temperature and humidity
2) Set address: in normal display status, press ''SET'' key, upper half display ''Add'', when bottom half number flicker, press ''+'' or ''-'' key to set address (defaults to 1), the range is 1~255.
3) Set key: when setting, the key time interval is 10 seconds, more than 10 seconds will automatically to the normal display state.
Guarantee
12 month. Damage due to exceptional operating conditions, careless handling or misapplication will void the guarantee.
Notice
The mounting direction of soleplate should be attended. Avoid the following:close proximity of the transmitter to a heating element, a cold or hot wall, direct exposure to sun rays, etc.
Be sure to cut off the power supply before mounting and changing transmitter.
If the mounting surface with a large temperature difference between the measured environmental, recommend the use of stents installed more than 20cm away from the mounting surface.
It will be necessary to calibrate the transmitter when it is using above 12 month.
Some product specifications may be changes, see the indicator of product identification on the subject.
