key Display the delay time value. Press key to display "HY1",
display the setting value two seconds later. Positive value is cooling
control, negative value is heating control. The delay time is the
difference between On and Off. When MRT is On, the indicator light
beside RL1 is on. For example (1) L1=+25 Celsius degree; HY1=-03
Celsius degree, the output control is heating mode. Show that RTL1 is
off when the temperature is 25 Celsius degree; RTL1 is on when the
temperature is 22 Celsius degree. For example (1) L1=
10 Celsius
degree; HY1=+02 Celsius degree, the output control is cooling mode.
Show that RTL1 is off when the temperature is
10 Celsius degree;
RTL1 is on when the temperature is 8 Celsius degree.
4) If the coupling end of the probe head of temperature control instrument
is open circuit or out of the range, display "PFA", RL1 output will work
according to the permanent setting value of SETUP.
The setting of MTR is completed by
changing the control parameters. The parameter setting can be completed
by the following produces.
1) Turn off the temperature control instrument, at the same time press
the key and hold up, turn on the power supply, then display "PAR",
press and key repeatedly to choose the setting items of parameters,
after displaying value press key to change the value, and then press to
save the value.There is no necessary to display the value from one
parameter to another parameter to press key directly, also can choose
certain specs parameter and set the parameter according to the
arrangement plan.
key Press or to increase or decrease the values of
parameters. Press and hold up to change the parameter values at a
quick. The biggest and smallest values have been set in the "SETUP".
Change it according to the first part of 6.4.2 and the following
instruction.
2) key When the MTR works normally, press key, the screen
display"L1", display the setting value two seconds later. If "L1" achieve
the settingvalue, the control output RL1 changes from On to Off. If press
key when set the parameters, the parameters can be saved, and
switch to control mode. Return to control mode automatically six
seconds later without pressing any key.
