Key Operation Instruction
•
Check parameter:
In normal working status, the screen
display real time temperature.press
. it dispay the setting
temperature value.press
. it dispay the difference value.
Press
to back to normal display.
•
Set parameter:
In normal working status, press
S
for 3s to
enter set parameter mode. Press
or
to switch from
F1-F4.(see menu code table). Press
S
to display the
parameter set value of the current code.Press and hold
S
，
Press
or
again to adjust up and down the parameter
setting value of the current code. Press and hold both
S
and
or
simultaneously to choose and adjust the
parameter value of the current menu value promptly.After
finishing the setting,press and release
instantly to save
the parameter modified value and return to normal display.
If no key operation within 30 seconds, system won
’
t save
modified parameter, screen back to display normal
temperature. Screen display
“
Er
”
if error appears during
parameter saving, and back to normal working status in 3
seconds.
•
Restore system data:
When electrified, system will check
itself, screen will display
”
Er
”
if error exit, please press any
key at this time, and it restore default value and enter into
normal working mode. it is advised to reset the parameter
value under this condition.

Operation Instruction
•
In normal working status, hold
for 3seconds to power
off, hold
for 3seconds to power on.
•
In normal working status, the screen display
RT
(real time
temperature value). the controller can also switch the
working mode between heating and cooling.
