Merchandiser temperature is maintained by an electronic thermostat that cycles
the condensing unit on and off automatically. On cold-wall (CW) models, the
electronic temperature control is located on the left end under the hood on
outdoor units and to the left of the condensing unit on indoor skirt hood models.
Minimal temperature adjustment (5 degrees F min/max adjustment) is possible
by pressing the up or down arrow buttons for colder or warmer temperatures
since the electronic control is pre-set at the factory. DO NOT adjust the thermostat
without consulting Polar Temp.
The electronic control is factory set with a computer at the factory therefore there
is no need to make field adjustments. The digital display on your new Polar Temp
Ice Merchandiser will show fault codes and other information as described below:
“E01” on the digital display means “faulty air sensor”
“E03” when used is faulty “condenser air sensor”
“OFF“ on the digital display means the refrigeration system has been
“turned off”
Electronic Temperature Control
Cold Wall Models – ERC101A • Starting May 2012
“OFF“ on the digital display means the refrigeration system has been
“turned off”
“ON“ on the digital display means the refrigeration system has been
“turned on”
“DEF” on the digital display means the refrigeration system is in “defrost
cycle”
“VH” indicates “voltage high”
“VL” indicates “voltage low”
The four buttons on the digital display will do the following:
Press and release the bottom left hand button (“OFF or ON“will show
on the digital display)
Press and release the top left hand button will put the system into
defrost mode (“def” will show on the digital display) The system will
automatically return to refrigeration cycle after 15 minute defrost
period and the coil defrost temperature reaches 55º F. If the defrost
terminate temperature is not 55°F, it will continue to a maximum
of 25 minutes. The system will go into defrost every 120 minutes of
“compressor” run time.
If the electrical power supply is interrupted the electronic control will
always start automatically in the refrigeration cycle after a short
delay.
