If you didn t use up all the steps for programming you can use one of the unused steps for that For example assuming step 10 and 11 are unused setC 10 100 C 11 10 and t10 9999 This sets Step 10 to control the temperature at 100 degrees for 9999 minutes To begin the program startRun V key press SET once to display StEP use Ato go to StEP 10 Press SET twice The controller will run just like regular controller with PV displayed ontop and SV in the bottom Youdon thave to do this every time the controller powers up assuming the A M parameter has not changed from default lt will remain running StEP 10 until 9999 minutes 7 days runs out or until you reset it for another application 2 Put the program on hold mode This can be done either by manually pressing the Hold button at the desired temperature or by programming a hold step by setting tXX 0 7 3 just want to run the oven at 800 degrees for 120 minutes When I setC01 800 t01 120 the controller SV first displays 800 then it starts dropping with time Did do something wrong This is the most common mistake first time users make Since this is a ramp controller nota step controller the time t01 or tXX is not the time that controller will stay at C01 or CXX itis the ramping time that controller will take from temperature C01 to C02 To hold the temperature constant for 120 minutes you need to set two steps at the same temperature or a 0 degree ramp C02 C03 800 in this case Then set
