Under normal working status, press "up" key it displays temperature
setting value; press "down" key it displays the differencevalue.
2. The way to set parameter:
Under controller normal working status, press "s" key for 3s or
more to enter parameter modifying mode, and the "Set"
indicatorlight on, screen displays the first menu code "F1".
Press "up" key or "down" key to adjust up and down and display the
menu iem and the code of the menu item.Press "s" key to display the
parameter value of the current menu. Press both "s" key and hold
"up" key or "down" key simultaneously to choose and adjust the
parameter value of the current menu value promptly. After finishing
the setting, press and release the "(I)" key instantly to save the
parameter modified value and return to display the normal
temperature value. If no key operation within 10 seconds, system
won't save modified parameter, screen back to display normal
temperature.
3. Restore system data
When electrified, system will check itself, screen will display
"Er" if error exit, please press any key at this time, and it
restores default value and enter into normal working mode, it is
advised to reset the parameter value under such conditions.
Operation instruction
Under controller normal working status, press and hold "(I)"key for
3s can turn off the controller; Under controller "off" status,
press and hold "(I)" key for 1s can turn on the controller.
Under the controller normal working status, screen displays the
current measuring temperature value; also the controller can also
switch the working mode between heating and cooling.
Controller starts refrigerating with cool indicator light on when
the measuring temperature value >= temperature set value
+difference value, and the refrigerating relay is connected; If the
“Cool” indicator light flashes, it indicates the refrigerating
equipment is under compressor delay protect status; when the
measuring temperature values temperature set value, the Cool
indicator light on, and refrigerating relay disconnects.
System starts heating when the measuring temperature value <=
the temperature set value-difference value, and the "Heat"
indicator light on, the heat relay connects; When the measuring
temperature >= temperature set value, the "Heat" indicator light
is off, and the heat relay disconnects.
Error/Alarm description
Alarm when sensor error: Controller activate the sensor error alarm
mode when sensor open circuit or short circuit, all the
running status is closed off with the buzzer alarms, and the nixie
tube displays “EE”,Press any key can cancel alarm sound, system
back to display the normal temperature when the error and the fault
is cleared.
Alarm when the measuring temperature exceeds temperature measuring
range:Controller activates the error alarm function when the
measuring temperature exceeds the temperature measuring range, all
the running status is closed off with the buzzer alarms, and the
nixie tube displays “HH”,Press any key can cancel alarm sound,
system back to display the normal working mode when the temperature
restore to normal measuring range.
Safety Regulations
★Danger:
1.Strictly distinguish the sensor down-lead, power wire and output
relay interface from one another, and prohibit wrong
connections or overloading the relay.
2.Dangers: Prohibit connecting the wire terminals without
electricity cut-off.
★Warning:
Prohibit using the machine under the environment of over damp, high
temp., strong electromagnetism interference or
strong corrosion.
★Notice:
1.The power supply should conform to the voltage value indicated in
the instruction.
2.To avoid the interference, the sensor down-lead and power wire
should be kept a distanc
