Model: W1218 Display: Red LED Probe operating temperature: -20°C to 100°C Display operating temperature: -10°C to 60°C Working voltage: 12V DC Measurement accuracy: 0.1°C Control accuracy: 0.1°C Return difference accuracy: 0.1°C Refresh rate: 0.5s Measuring input: NTC (10K 0.5%) length 0.8 meter, waterproof sensor Output: 1 way 10A /250VAC 20A/14VDC relay Humidity: 20% to 85% Power consumption: ≤ 35mA (static), ≤ 65mA (relay close) Weight: Approx. 200g/7.0oz Package includes: 1pcs digital thermostat + 1pcs probe cable Mode Description Set Range Factory Setting P0 Heating/Cooling H/C C P1 Return Difference 0.1 to 15 2 P2 Set Linit Max 110 110 P3 Set Linit Min -10 -10 P4 Temperature Correction -7 to 7 0 P5 Delay Start 0 to 10 min 0 P6 High Temperature Alarm -10 to +110 OFF Factory Reset ON/OFF OFF PROGRAMMING: Press the SET button, the temperature that flashes on the display can be changed with the + and - keys. Press and hold the SET button for a few seconds. 0P0 will appear on the display Program responsible for heating "H" or cooling "C" If 0P0 is on the display then press SET again And with the keys + and - we change the program 00H or 00C Pressing SET again exits from 0P0 Use the + and - keys to select the next program. From P0 "0P0" to P6 "0P6" P0 program for heating or cooling H/C P1 program in which we set the inertia temperature (higher in the case of set heating, less for the program cooling), after which the regulator is to switch off the heating or cooling. Range between switch-on (set) and off (0.1 to 15°C) Example: If the main heating temperature H is set to 24.0°C and program P1 is set to 0.7, the regulator switches on at 24.0°C and switches off at 24.7°C. If the cooling program C is set, the regulator switches off the contact at 23.3°C P2 program in which we set the upper temperature limit from -4.5 to 110°C P3 program in which we set the lower temperature limit from -50 to 105°C P4 program in which we adjust the thermometer in the range from -7 to 7°C Set when the display temperature is different from ambient temperature (compare with other thermometers). P5 delay time 0-10 min P6 temperature alarm ON, OFF range 0 to 110°C RESET SETTINGS: Press + and - for a few seconds Example of switching on and off the gas furnace (including relay contacts) - heating H - minimum temperature 21°C - maximum temperature 22°C - temperature alarm 25.0°C Press SET, flashes the display with the set temperature, changes the setting to 21.0°C Press SET and hold down for 4 seconds, the display will show 0P0, press SET again and set 00H, press SET and display 0P1, SET set to 1.1.0, ie turn off the stove if temp is 1°C higher than desired, The stove will turn off at 22.0°C P2. set example 027 P3. set example 019 P4. set example 000 P5. set example, 000 P6.
