Quick User guide for set up with W1209
Press and hold ” SET ” Button to enter Menu
P0 C/ H C
P1 Backlash set 0.1 15 2
P2 Upper limit 110 110
P3 Lower limit -50 -50
P4 Correction -7.0 ~ 7.0 0
P5 Delay Start Time 0-10 mins 0
P6 High Temperature Alarm 0-110 OFF
PRESS and Hold both “+” “-“ Reset to Default Value.
Display Real time Temperature
Digital Thermostat Always shows the current temperature in its LED digital Display. if any button input it will wait
for 5 second then comes to default temperature in (degree “o C” )display mode.
Setting Up Required Temperature for Application
Step 1 Press “SET” Button now Display Start Blinking .
Step 2 Press “+” or “-” Button to required on display .please note each press changes temperature value by 0.1
release the button when required temperature show on display .wait for 2 second it will automatically stored in
memory . after that display start showing current temperature.
Setting multiple mode (P0 to P6)
pres and hold”SET” Button more than 5 second will show “P0” then using “+” “-” Buttons select from P0 to P6 Press “SET” again to enter required parameter.Then using “+” “-” change parameter values
Setting P0 Cooling or Heating
if set “C ” Relay will Energize when sett temperature reached .best for cooling in air condition system .
if set to “H” Relay will de energize when sett temperature reached .this for heating control application .
Setting P1 Hysteresis Value
This is for protect relay and device under control for condition we can set margin temperature that is we can set like ” 2oC” to set temperature 24 then relay will wait for margin temperature to change relay status .for example when temperate drift from 24 to 22 rely still energized protecting from continuous trig erring and hence protect the device.relay change its status only when temperature change is more than ” 2oC” (here margin temperature) value.
Setting Max Trig Temperature Value P2
safety value that protect trig temperature within a set limit if operator try to increase value more than limit system keep that in set limit defined by P2 Value. this will protect with the limit then protect entire system from any high temperature setting from operator or other users changes .
Setting Min Trig Temperature Value P3
safety value that protect trig temperature within a set limit if operator try to decrease value more than limit system keep that in set limit defined by P3 Value. this will protect with the limit then protect entire system from any Low temperature setting from operator or other users changes .
Setting Temperature Adjustments with Long Sensor wire P4
Parameter P4 is used for Sensor Temperature calibration for sensor cable length Calibration using “+””-” buttons
Setting P5 Trigger Delay Parameter
This is the range of i min to max 10 min delay time can set for relay energize when trigger temperature is reached .
Setting High Temperature Alarm P6
When the high temperature detected by sensor check with high temperature setting relay will switch off also for protection relay will not re – energize until the temperature fall below the value set by P6 Parameter .this is high temperature protection for the devices under control .This setting will protect the entire devices.
