Operation instruction:
A. Set The Starting Temperature:
Press the UP button once to display the starting temperature. Long press the UP button for about 3 seconds,The required temperature can be set by the UP and DOWN buttons.

B. Set Stop Temperature:
Press the DOWN button once to display the stop temperature. Long press the button for about 3 seconds and the stop temperature number flashes. The required temperature can be set by the UP and DOWN buttons.

C.Press UP ① button and Up ② button at the same time to setting mode:
Press UP ① and UP② buttons for 3 seconds at the same time to enter the setting mode, display P0, the first group temperature delay, press UP ② and DOWN ② to adjust, 0~60 minutes, default 0, after adjustment, press UP ① since P1, the second group temperature delay, press UP ② and DOWN ② to adjust, 0~60 minutes, default 0. （P2-P3 has no mode）

Menu Instruction

Code	Function	Set Range	Default
P0	①: Delay start	0-60 minutes	0
P1	②: Delay start	0-60 minutes	0
P2	Has no mode	/	/
P3	Has no mode	/	/

D. Reset Factory Settings:
When the power is on, press the DOWN ① and DOWN ② buttons at the same time for 3 seconds. The reading shows 888, and then the controller automatically jumps to the detected temperature.

E. Temperature Correction:

Press UP ① and Down ① at the same times for 3 seconds to display 0.0, and then set the value by pressing the Up① and Down① buttons.
Positive Value = Measured Value +Corrected Value( NO.2 temperature correction is the same method, press UP ② and Down ② buttons )

F. Heating Cooling Method:

Operation Method

Heating Mode

Start temperature < Stop temperature

Program automatically determines the working mode is heading mode

Cooling Mode

Start temperature > Stop temperature

Program automatically determines the working mode is cooling mode

Note:
1. 12V/24VDC W1088 can use the transformer or 12V/24V DC Power Supply.
2. W1088 is Direct Output: The output and input voltage are synchronized.
When the temperature controller is working ( the indicator light is on), the output voltage is the same as input voltage;
When the temperature controller is off (the indicator light is off), the output will do not have voltage.
