Heating/ Cooling setting

• CASE 1 Heating: control the water heater, heat to 65 Cto stop. the temperature drops back to 50 C and start heating again
• Step 1:heating mode, starting temperature <stop temperature
• Step 2: Press and hold the”A “button to start the temperature ashing. Use”A V”to set the starting temperature to 50 °C. Step 3: long press the”” button 3 seconds to stop the temperature flashing. Use”A V “to set the stop
• temperature to 65°C. The setting is completed!
• CASE 2: Cooling: the fan is ventilated to 26 C to stop, the temperature is raised to 30 Cand the ventilation is started again.
• The first step: cooling mode, starting temperature> stop temperature
• Step 2: Press and hold the”A “button to start the temperature flashing.
• Use”A V to set the starting temperature to 30 °C.
• Step 3:1ong press” button 3 seconds to stop the temperature flashing.Use” AV “to set the stop temperature to 26°C. The setting is completed!

Wiring diagram

Note : There is no voltage output from the output terminal of the thermostat, So the device needs to be connected to a power supply

Indicator light status instruction

Error description

Alarm when sensor error: Controller activate the sensor error alarm mode when the 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 an 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 proper distance.
