XH-W2024 Automatic Thermostat Cooling Heating 2 Group Output Upper and Lower Limit 2 Relay Output

The main function:

 

This controller can be set to a constant temperature, and a set of temperature difference. When the temperature is lower than the constant temperature-temperature difference, the heating is started and the constant temperature value is stopped. When the temperature is higher than the constant temperature + temperature difference, the heating is started and the constant temperature value is stopped.

Basic settings:

 

Press SET once to display the P1 constant temperature value (stop), then press SET to flash, press the up and down keys to modify the constant temperature value (stop) temperature. Switch to P2 for the temperature difference, and press the up and down keys to modify the temperature difference.

 

Error code:

 

LLL: Sensor is open or damaged

HHH: Sensor short circuit or out of measurement range

---: Sensor communication failure, check if the sensor connection is normal

Blinking screen: in the setting state or prompting high and low temperature alarm

Code	Description	Setting range (method)	Factory settings
P1	Constant temperature value	-49~110°C	25
P2	Temperature difference	0.1~20	1
P3	Heating delay	0-600 second	0
P4	Cooling delay	0-600 second	0
P5	High temperature alarm	-49~110°C	110
P6	Low temperature alarm	-50~109°C	-50
P7	Temperature correction	-10.0~+10.0	0

P1: Constant temperature value

Set the temperature value required by the user.
P2: Temperature difference

When the real-time temperature >= constant temperature value + temperature difference starts cooling, the work reaches the constant temperature value stop. 
When the real-time temperature <= temperature difference - temperature difference starts heating, work to the constant temperature value stops 
P3: Heating delay

When the heating needs to be started, the heating will not be started immediately. It needs to be started after the P3 value is run. When the delay occurs, the corresponding heating lamp will flash! Set the unit to seconds. If you need to start the delay immediately, you can lower the value and set it to 0.

P4: Cooling delay

When the cooling needs to be started, the cooling will not start immediately. It needs to run the P4 value to start. When the delay occurs, the corresponding cooling light will flash! Set the unit to seconds. If you need to start immediately without delay, set this value to 0.

P5: High temperature alarm

A set of temperature values ?‹​greater than the upper limit can be set to a high temperature alarm. When the temperature is higher than this value, the screen temperature flashes and the buzzer beeps! When the temperature is lower than this value, the alarm is automatically released.

P6: Low temperature alarm

A set of temperature values ?‹​below the lower limit can be set to a low temperature alarm. When the temperature is lower than this value, the screen temperature flashes and the buzzer beeps! When the temperature is higher than this value, the alarm is automatically released.

P7: Temperature correction

When there is an error between the displayed temperature measurement value and the actual temperature value, it can be corrected by this function, and the corrected value will be automatically added to the real-time temperature, such as: display temperature = measurement temperature + temperature correction value
