CAUTION
If using Rc connections, take care not to coat with too much sealant. Foreign matter or burrs
in the pipes may also cause measurement errors.
Do not apply a negative voltage or a voltage exceeding 5 V to the external setup voltage
input terminal. Doing so might cause malfunction or equipment failure.
When using a relay for external contact input and/or external 3-way switching input, always
use a relay designed for micro-current use (with gold contacts). Failure to do so could cause
faulty contact, resulting in malfunction.
If there is a risk of a power surge caused by lightning, use a surge protector to prevent fire or
equipment failure.
Gas type switching by external contact input, flow rate switching, and analog input/output
voltage range switching by external 3-way input switching should be done only after
setting the operation mode to fully closed. Switching while controlling could cause large
fluctuations.
Be sure to check that the wiring is correct before turning the power on. Incorrect wiring could
cause damage or malfunction.
Do not apply excessive force to the cables or connector while the connector cable or the AC
adapter is connected. Doing so may damage the connector or the circuit board.
Do not operate the console keys using a sharp object such as a mechanical pencil or
screwdriver. Doing so might damage the console.
When discarding the device, dispose of it as industrial waste, following local regulations.
