Question 1

How do I set the difference value (F2) for the thermostat?

Accepted Answer

Press and hold the key until you enter the parameter setting mode. Use or to switch between F1-F4 parameters and select F2, then press and hold S while adjusting with or to set the desired difference value.

Question 2

What is the compressor delay time for this thermostat?

Accepted Answer

The default compressor delay time (F3) setting is 3 minutes. To change it, press and hold S until you enter the parameter setting mode, then adjust F3 accordingly.

Question 3

How do I enter the menu to change thermostat settings?

Accepted Answer

Hold the SET key for 3 seconds to enter the menu list; the display will show the code F1. Once in the menu, you can press SET to view existing values and use the direction keys to change them.

Question 4

What happens if I don't complete a setting change within a certain time?

Accepted Answer

If no operation is performed within 8 seconds after entering a menu, the new data will be discarded and the thermostat will return to its normal status. This prevents accidental changes from being saved.

Question 5

Can I check the temperature setpoint without entering the full menu?

Accepted Answer

Yes, in normal status you can press the UP key to quickly check the temperature setpoint (F1) without entering the full menu. Similarly, press the DOWN key to check the hysteresis value (F2).

Question 6

What does the STC-1000 do in terms of heating and cooling?

Accepted Answer

The PURGEAR STC-1000 is an All-Purpose Temperature Controller that automatically switches between heating and cooling modes. It features two relays, allowing for the connection of one refrigerator and one heater to manage both systems.

Question 7

How should I connect the wiring to the STC-1000?

Accepted Answer

The STC-1000 does not output AC electricity, so all live and neutral wires must be connected to each port. Jumper wires can be used for convenient connections to make the setup easier.

Question 8

How do I turn the thermostat off and on?

Accepted Answer

Hold the ENTER key for 3 seconds to power off or on the thermostat. This is the standard method for toggling the device's power state.

Question 9

How do I save a temperature setting after changing it?

Accepted Answer

After using the direction keys to change the value in the menu, press the ENTER key to save the data. Make sure to do this within 8 seconds, or the changes will be discarded.

Question 10

What is the temperature range that the STC-1000 can control?

Accepted Answer

The temperature control range for the Purgear STC-1000 Digital Thermostat is -50°C to 99°C.

Question 11

What happens when an error occurs during setup?

Accepted Answer

If there's an error while saving settings, the screen will display 'Er' temporarily. The system will revert to normal operation after 3 seconds without any key operations.

Question 12

How do I manually reset the thermostat if it displays an error?

Accepted Answer

After powering on and seeing a displayed 'Er', press any key to reset the parameter values and restore default settings, allowing the system to start normally.

Question 13

What is the power supply range for this thermostat?

Accepted Answer

The Purgear STC-1000 can operate with AC90~250V at 50/60HZ or DC12V and DC24V.

Question 14

How do I change the operating mode between heat and cool?

Accepted Answer

In normal operating status, switch modes by pressing S for 3 seconds to enter parameter setting mode. Select either F1 (temperature set value) or use up/down keys to adjust the setting accordingly.

Question 15

What does it mean if the 'Set' light is on?

Accepted Answer

'Set' light being on indicates that the thermostat is in parameter setting status.

Question 16

How do I check if the sensor is functioning correctly?

Accepted Answer

Press and hold S button for 3 seconds to enter set parameter mode, then navigate to F4 (temperature calibration value) to detect sensor error. Default temperature calibration value range is -10℃～10℃.

Question 17

What should I do if my thermostat starts displaying 'Er'?

Accepted Answer

'Er' indicates an error. If it appears during setup, the system reverts to default settings when you press any button and enters normal operating mode.

Question 18

How do I restore the STC-1000 to factory settings?

Accepted Answer

Hold both the UP and DOWN keys simultaneously for 5 seconds to restore factory settings. This will reset all configurations back to their default values.

Question 19

How does the temperature range work on the STC-1000?

Accepted Answer

The aimed temperature range is defined from F1 minus F2 (if lower than this, heating triggers) to F1 plus F2 (if higher than this, cooling triggers). This creates an automatic switching between heating and cooling modes.

Question 20

What are the four main functions available in the Function Menu?

Accepted Answer

The four main functions are F1 (Temperature Setpoint), F2 (Temperature Hysteresis), F3 (Protection Delay Time for the Compressor), and F4 (Temperature Calibration). Each can be accessed and adjusted through the menu system.

Question 21

What is the main purpose of the Purgear STC-1000 Digital Thermostat?

Accepted Answer

The Purgear STC-1000 is a versatile all-purpose temperature controller designed to manage both heating and cooling systems. It features two relays, allowing connection of one refrigerator and one heater, and automatically switches between heating and cooling modes based on your temperature settings.

Question 22

What happens if I don't save my settings within the time limit?

Accepted Answer

If you don't perform any operation within 8 seconds after making changes, the new data will be discarded and the thermostat will return to its normal operating status.

Question 23

What is temperature hysteresis (F2) and why is it important?

Accepted Answer

Temperature hysteresis (F2) defines the temperature range around your setpoint. The thermostat uses it to calculate the upper limit (F1 + F2 for cooling) and lower limit (F1 - F2 for heating), preventing the system from switching on and off too frequently.

Question 24

Why does the manual state that live and neutral wires must be connected to each port?

Accepted Answer

The STC-1000 does not output AC electricity, so all live and neutral wires must be connected to each port for proper operation. You can use jumper wires for convenient connections during installation.

Question 25

How do I check the current temperature setpoint without entering the menu?

Accepted Answer

When the thermostat is in normal status, simply press the UP key to display the temperature setpoint (F1) on the screen.

Question 26

What are the four main function settings available in the STC-1000 menu?

Accepted Answer

The thermostat includes four main functions: F1 (Temperature Setpoint), F2 (Temperature Hysteresis), F3 (Protection Delay Time for the Compressor), and F4 (Temperature Calibration).

Question 27

How do I access the thermostat's menu settings?

Accepted Answer

Hold the SET key for 3 seconds to enter the menu list; the display will show the code F1. You can then press the SET key to view existing values and use the direction keys to change them. (Page 1)

Question 33

Does the STC-1000 output AC electricity?

Accepted Answer

No, the STC-1000 does not output AC electricity; therefore, all live and neutral wires must be connected to each port. Jumper wires can be used for convenient connections. (Page 1)

Question 34

What is F2 in the function menu?

Accepted Answer

F2 represents Temperature Hysteresis in the thermostat's function menu. You can check the hysteresis value by pressing the DOWN key in normal status. (Page 1)

Question 37

How do I set the target temperature range on my STC-1000?

Accepted Answer

Hold the SET key for 3 seconds to enter the menu and display F1 (temperature setpoint). Press SET to view the current value, then use the direction keys to adjust it. The aimed temperature range runs from F1 - F2 (triggers heating if lower) to F1 + F2 (triggers cooling if higher). Press ENTER to save your settings.
