Mode Selection
This controller has 5 different modes: program run, program hold, program
stop, parameter setting, and programming mode. Before powering on the
controller, please connect the sensor cable to it. If no sensor is connected, the
controller will show error code “Err”, indicating no sensor is detected.
When the
controller is powered on, it enters the Program Hold mode. It will flash
measured reading temperature
value and “hold” alternatively
. The controller
will start controlling temperature according to the saved setting, but the timer is
paused.

Program Running
: The controller executes the saved program. The green
indicator RUN is lit, and the timer is running. The display window should show
the current temperature reading. The controller will send power to its
heating/cooling sockets to regulate temperature. When the program is running,
press PAUSE key will put the controller to Program Hold mode.
Program Holding
: Controller pauses the time but it still regulates the
temperature at the current set value. The RUN indicator is off. The display
window flashes between the reading temperature
and “Hold”. To resume the
program, press START key. To completely stop the program, hold the STOP
key for 4 seconds.
Program Stop
: The execution of the program is terminated. Controller outputs
are deactivated and timer is also stopped. The RUN indicator is off. The display
window flashes between the reading temperature
and “Stop”. To start the
program, press the START key. The controller will start regulating the program
from the first step.
Programming Mode:
Review and edit temperature set value and set time for
each steps. When the controller is in Program Run, Hold, or Stop mode, press
SET key to enter the Programming mode. Please see Figure 4 for details.
Parameter Setting Mode:
Review and edit system parameters. When the
controller is in Program Run, Hold, or Stop mode, hold the SET key for 2
seconds to enter the Parameter Setting mode. Please see Figure 3 for details.

Parameter Setup
Please see Table 2 for a list of parameters and see Figure 2 for the flow chart of
how to set the parameters. Please note that parameters will remain unchanged
unless you press set key to confirm the change.

Note 1.
AH, deviation high alarm; AL, deviation low alarm:
Assuming measured temperature is PV and set temperature is C. When PV - C
is above AH, the built-in buzzer will turn on (deviation high alarm); when H
–
PV is above AL, the built-in buzzer will turn on (deviation low alarm). User can
mute the alarm by momentarily pressing the Mute key. The alarm will remain
inactive until the process value moves out of the alarm zone. Both alarms are
deviation alarms, i.e., if AH = 20, AL = 30, and the Set Temperature (C) is 50F,
the alarm will be activated if the temperature is above 70F or below 20F. The
alarm function is suppressed at powering up or when the program is jumped
from one step to another step. It will be activated automatically once the
measured temperature enters the none-alarm zone (between C - AL and C +
AH).
Note 2.
Hy, Temperature Control Hysteresis Band, or Temperature Control
Dead Band:
This parameter set up a dead band (between C - Hy and C + Hy) within which
either the heating device or cooling device will not work. The minimum value
for Hy is 0.5. The Hy value should not be too small if the system has sluggish
response. Otherwise, it may result in the heating device and the cooling device
working against each other, wasting energy and causing oscillation.
Note 3.
CdF, Cooling Differential:
This is the differential band between turn on and turn off the cooling device. It
is set to the higher side of the temperature set point (C + Hy). The cooling
device will turn on when temperature is above (C + Hy + CdF), and turn off
when temperature is below (C + Hy). For compressor based cooling device, the
CdF value should not be set too small to prevent frequent cycling.
Note 4.
HdF, Heating Differential:
This is the differential band between turn on and turn off the heating device. It
is set to the lower side of the temperature set point (C - Hy). The heating
device will turn on when temperature is below (C - Hy
–
HdF), and turn off
when temperature is above (C
–
Hy).
For example, if Set Temperature C = 50, Hy = 5, CdF = 3, HdF = 2, then the
heating device will turn on when process temperature is lower than 43 (C - Hy -
HdF) and turn off when process temperature rise above 45 (C - Hy). The
cooling device will turn on when process temperature is above 58 (C + Hy +
CdF) and turn off when process temperature drop below 55 (C + Hy).
Note 5.
oFS, Temperature Offset:
oFS is used to compensate the error produced by the sensor or input signal
itself. For example, if the unit displays 37 when the actual temperature is 32.
Set parameter oFS = - 5 will make the controller display 32.The displayed
process temperature = actual measured tempe oFS.
