History Screen
The history screen displays the high and low temps read on the inputs since the last history
reset. They are displayed in the units you have selected in the preferences. It is accessed by
entering an
‘h’
at anytime. Hitting a ‘1’ at the prompt resets the high and low readings to current
readings.
Power LED
The green LED should like and blink once a second when the controller is operating properly. If
the LED is not lit, check the power inputs and verify you are pro12VDC and Ground to
the power inputs located next to the LED. Verify polarity is correct.
When power is first applied, it can take approximately 6 seconds to initialize.
Installation and Wiring Info
Temperature Sensor Inputs and Wiring
The temperature sensors sold with the controller are matched in characteristic to the controller
and will provide the most accurate readings. Using other 10K NTC thermistors is not
recommended. There are water-proof versions of the temp sensor available as well.
Temperature sensors may be extended 50 ft with twisted pair telephone cable or CAT5 cable
without dramatically affected the reading accuracy. Do not include power wiring in the bundle to
other devices as it may put noise on the temperature reading. Always separate measurement
sensor wiring from power / load device power wiring where possible.
The sensor inputs are wired with a common terminal between each two inputs. This common
wire should have one wire from each temp sensor input adjacent to it.
