① Cooler On/Off control
▶ When the current temperature becomes higher than a configured temperature, the main
output relay turns on.
▶ You can use a delay timer to protect a compressor.
② Heater On/Off control
▶ When the current temperature becomes lower than a configured temperature, the main
output relay turns on.
Note: In general, the B contact of a relay is used for reverse output. In this case, be
cautious since the contact B is ON even though the power to the unit is turned off.

▶ In order to change the delay timer setting, press SET key for longer than 5 seconds
while the display unit shows the current temperature. Release the key when the display
unit shows diF. Press SET key several times to select dLt.
▶ After selecting a value using Up or Dn key, press SET key to store the setting in the
memory.
Description: When the delay time expires, the output turns on.

▶ How the delay timer works
Case: the delay time is 0 second => the relay turns on as soon as output signal arrives.
Case: the delay time is 5 seconds => the relay turns on after 5 seconds upon the arrival o
output signal.
▶The following diagram shows configurable items. Select an item by
pressing set key.
▶ Make a note of the factory default settings before changing any one of them. Before
making any change, understand and verify the validity of your setting(s).
