Press SET key momentarily. the controller will show Dt. Press Down key will
show T2. Press down key again, the controller will show T1. Press SET when
T1 is displayed will set the controller to display the sensor 1 temperature. Press
SET when DT is displayed will set the controller to display the differential
temperature. Press SET when T2 is displayed will set the controller to display
the Sensor 2 temperature.
If T1 is selected before the controller was powered off, it will display the T1 next
time when powered up. If either of the temperature sensors fails, the controller
will display "Err".
5. Parameter Settings
To change the target temperature and system parameters, press SET key for 5
seconds, the controller will enter the parameter set up mode. The first parameter
CSP will show on the display. Press SET key again to see the initial setting. Use
Up or Down key to modify the parameter value. Then press SET key to confirm
the change. The display will show the parameter again. Press down key to show
the next parameter. The instrument will automatically exit if no key is pressed for
10 seconds. Please see the following flow chart on parameter settings and table
1 for the parameter definitions.

Temperature Unit
Note 1. CSP is the set point for the cooling control channel. HSP is the set point
for the heating control channel. The value of the setting is the temperature
reading difference between the two probes. The unit is degree (Celsius or
Fahrenheit, depends on the setting). The relay for the cooling channel control
output will be on when the temperature difference is larger than the CSP. The
relay for the heating channel will be on when the temperature difference is
smaller than the HSP. For example, HSP = 5 means the controller will try to
keep the sensor 1 temperature reading 5 degrees different from the sensor 2
temperature reading, regardless the actual temperature reading of sensor 1 or
sensor 2 (as long as the both sensor are within their working temperature range).
The cooling channel can be used for controlling the solar water heater pump.
The heating channel can be used for controlling a dryer.
When DT is larger than CSP, C channel turns on. When DT is smaller than HSP,
H channel turns on. Please note, HSP has to be smaller than CSP so that two
channels do not work against each other. For example, when CSP = 20.0ºF,
HSP can be set to any value between -58.0 and 20.0 (ºF). For CSP, it can be set
to any value between -58 and 306 (ºF). If you set CSP to 55.0, the HSP will be
changed to 55.0 automatically.
CDF is the differential band (hysteresis band) between cooling set point and
on/off temperature. The controller will turn on when DT > CSP + CDF and turn
off when DT < CSP - CDF. For example, if CSP = 20.0ºF, CDF = 0.2, the
controller will turn on when DT > 20.2ºF and turn off when DT < 19.8ºF. Similarly,
HDF is the differential band (hysteresis band) between heating set point and
on/off temperature.
The controller will turn off at when DT > HSP + HDF and turn on again when DT
< HSP - HDF. For example, if HSP = 18ºF, HDF = 0.2, the controller will turn off
when DT > 18.2 ºF and turn on when DT < 17.8ºF.
Small differential band gives tight control; large differential band reduces the
frequency of cycle on and off. It will extend the life of relay and compressor.
Note 2. The value of the alarm setting, AH and AL are for the maximum and
minimum temperature difference between the two probes, not the actual
temperature reading of the probes. If the actual temperature reading of either
probe is out of its working temperature range, the controller will display error and
trigger the alarm buzzer also. When DT is larger than AH, alarm buzzer will be
on and display will flash AH and normal display. When DT is smaller than AL,
alarm buzzer will be on. And display will flash between AL and the normal display.
