*5: Provide a DC12 to 24V power supply.
Select a power supply capacity with an ample surplus for the connected load.
*6: The allowable current is 30mA or less.
Provide a load resistance such that the current becomes 30mA or less.
*7: Polarity is [+] for pin 1 and [-] for pin 2. Connect correctly.
Do not impress a voltage exceeding 24V across pins 1-2.
* A twisted pair cable (0.33mm

(22AWG)) should be used. Maximum length of cable is 150m.
* Use an external input and output cable with appropriate external dimension, depend-
ing on the number of cables to be installed.
6. 6. 4. Base heater terminal
This is the output signal for base heater. Output signal ON, when the outdoor tempera-
