Instruction Manual
1. Overview
This controller can be used for solar water heater control and drying oven control.
It has two sensor inputs. The temperature difference between the two sensors
(DT) is used for output control. The controller has two independent outputs also.
One of the output is to controller a cooling device so that DT is limited to a
specified range. The other output is for a heating device so that DT is maintained
to be not less than a specified range.
This controller is a plug and play controller. No wiring is needed for the heater or
cooler. Both the heating and cooling control modes are simple on/off control,
similar to a mechanical thermostat but with much higher precision due to
adjustable hysteresis band, precise sensor and digital read out. Anti-short
function is provided for cooling to protect the compressor from being turned on
with high pressure Freon.
Different operation temperature ranges of the two outputs can be set separately.
Once the cooling range is set, the controller program will automatically limit the
heating range to prevent both heating and cooling from being turned on at the
same time.
Two digital silicon band gap sensors are used. The advantage is being much
more reliable in moisture environment than thermistor sensor. They can be
immersed over extended period of time. They also have a more uniform
accuracy over an entire specified temperature range.

* Either the heating or the cooling device is limited to 10 Amps. The output
voltage is the same as the input voltage. When the controller is plugged into
120V AC, the output will be 120VAC. If the controller is connected to 240 VAC,
the output will be 240VAC also.

4. Setup Flow Chart
During the normal operation, the controller offers three different displaying
modes: temperature reading of Sensor 1, T1; temperature reading of sensor 2,
T2; or, the temperature difference between the two sensors, DT.
Following chart shows how to change the display from one reading to the other.
