Notes for Installation
• Before wiring, please read the instructions
carefully and be sure to understand the
function of every contact so that you can
make correct wire connections. Control
loads cannot exceed the ratings.
• The temperature controller cannot be
installed in an area where water flows, a
dirty area, an area of high moisture, or in an
area with high temperatures. Please pay
attention to EMC problems and prevent the
temperature controller from collisions with
other objects.
• The sensor cable leads must be kept away
from the main supply in order to avoid high
frequency noise. 0.75-1.5mm 2 flexible cords
should be used for wiring control load
terminals.
• The evaporator sensor must be installed
between the fins of the evaporator in the
area where ice is the thickest. Do not place
the evaporator sensor near the electric
heater.
• If the temperature controller is disturbed,
please cut off the power supply and reset.
