DIGITAL DIMMING THERMOSTAT DAY & NIGHT + TIMER
DTC-120
User Manual
Instructions:
DTC-120 is one of latest developed dimming thermostat series products which are applied to aquatic
and reptile market. Practicality functions, elegant appearance.
One channel is for temperature PID heating, one channel for timer controlling.
We adopt PID techniques, a very accurate temperature control mode, DTC-120 operates by reducing the
current (amps) to the heating device which in turn reduces the amount of electricity it uses and the
amount of heat it produces, The DTC-120 uses its intelligence to determine how much current to supply,
when the sensor reading starts to get closer to the target temperature it will reduce the current so that
the area will not over heat once the target has been reached. Also if the temperature starts to fall, the
DTC-120 will start to send power to your heating devices to prevent the temperature dropping below
the target temperature.
Compared to ON/OFF control mode, DTC-120 can avoid the unstable change of temperature and lighting
caused by switching on & off frequently, so DTC-120 is more conducive to the health of reptiles, even
DTC-120 can make the heater or other electrical equipment maintain long service life, and save money
for users.
Main features:
1. Big LCD display, friendly interface, easy to read, operates and set the parameters.

Parameters setting:
Parameters would be set according to the following circular mode in the first time. All the parameters
are set and saved instantly.
First of all, make sure the power is on.
1. Daytime temperature setting:
Press SET key for 3 seconds to display the default temperature value while icon SET and flashing,
then press UP or DOWN key to select the ideal temperature you want.
2. Nighttime temperature setting:
Press SET key once to display the default temperature value while icon SET and flashing, then
press UP or DOWN key to select the ideal temperature you want.
3. Over temperature alarm setting:
Press SET key once until lower part of icon flashing and display the current over temperature
alarm value, press UP or DOWN key to select the idea over temperature you want.
4. Timing setting:
Notice that while start time and end time is same, this timing control become invalid
4.1. First timing control L1:
A. Start time setting: Press SET key until display L1 and FROM icon flashing, at the same time display the
default time, press UP or DOWN key to set the hour;
After hour set, press SET key to set the minute, press UP or DOWN key to set the value;
B. End time setting: When start time is already finished, press SET key and then TO icon flashing, you
can set end time in the same method.
4.2 Second timing control L2: The same operation with first timing control L1.
5. Real-time setting:
Press SET key, icon flashing and display current hour set value, press UP or DOWN key to adjust

the system time;
Press SET key and then set minute value in the same method.
6. Daytime time setting:
A. Start time setting: Press SET key, and icon flashing, at the same time FROM flashing and
display default hour value, press UP or DOWN key to modify the value.
After hour set, press SET key to set the minute, press UP or DOWN key to set the value;
B. End time setting: When start time is already finished, press SET key and then TO icon flashing, you
can set end time with the same method of start time setting.
7. Night time time setting:
A. Start time setting: Press SET key, and icon flashing, at the same time FROM flashing and
display default hour value, press UP or DOWN key to modify the value.
After hour set, press SET key to set the minute, press UP or DOWN key to set the value;
B. End time setting: When start time is already finished, press SET key and then TO icon flashing, you
can set end time with the same method of start time setting.
Tips:
1. If current menu don’t need adjustment, press SET key directly to switch to next menu, press SET key
for 3 seconds to exit and save settings.
2. Parameters of temperature and timer can be recycled view by pressing UP or DOWN key in normal
status.
3. The product returns to normal working condition automatically without any key operate in 15
seconds.
4. Parameter adjustment: Press UP or DOWN key and hold, enter into quickly adjusting state.
Set high and low limits of the set temperature:
In normal working status:
A. High limit: Press UP key for 5 seconds to display current high temperature limit setting(50℃), and
then press UP or DOWN key to modify the set value.
B. Low limit: Press DOWN key for 5 seconds to display original low temperature limit setting(0℃), and
then press UP or DOWN key to modify the set value.
For example: if the limits are default value, the set temperature can be adjusted between 0~50℃; if the
high limit is 30C, low limit is 10C, the set temperature can only be adjusted between 10~30℃
Heat controlling function:
Heating systems works in below situation:
the measuring temperature ＜the set temperature
Heating systems stops working in below situation:
the measuring temperature ＞the set temperature
Timing setting:
FROM: timing of turning on light; TO: timing of turning off light
If the system time is during FROM time and TO time, the light will light when timing setting has
adjusted and saved. For example, original timing starting time is 8:30, original timing ending time is
18:30, new timing starting time is 6:00, new timing ending time is 18:00, the system time is 7:00, you
will see the light is on. If not, the light is off.
Others:
1. Over temperature alarm: upper part of icon rapid flashing with "drops" alarm sounds and
display the measuring temperature in below situation:
A. the measuring temperature ≥the set temperature + Alarm over temperature
B. the measuring temperature ≤the set temperature - Alarm over temperature
2. Exceed temperature measuring limits alarm: with "drops" alarm sounds at the same time.
the measuring temperature ＜0.0℃, display LLL: super low temperature;
the measuring temperature ＞50.0℃, display HHH: super high temperature;
3. Probe fault alarm: when probe have open circuit or short circuit faulty, display error message of
probe faulty "ERR"
Mute alarming manually:
A. the 1st and 2nd alarm can be muted by pressing any key, but probe fault alarm sound cannot
eliminate.
B. Press UP or DOWN key at the same time for 3 sec or more, the menu is available to choose whether
to eliminate alarm sound, AL: have alarm sounds, NO: have no alarm sounds.
C. You can choose one and press SET to save and exit.
Socket output control load:
I: heating output; II: timer output, such as lighting or oxygen pump.
Remarks :
When you choose a heater, please choose appropriate capacity one, for low capacity one will take
very long time to reach the setting temp., but the high capacity one will make DTC-100 always working
at low capacity, So such unsuitable capacity of the heater/cooler will influence the heating / cooling
effect, and even cause damage to the heater/cooler and DTC-120 if you use them for long time.
Safety regulations:
Dangers:
1. Please avoid overload, load short circuit, misuse, human damage etc., which is not covered by the
warranty. Load short circuit can damage the dimming output immediately!
2. DO NOT connect the wire terminals without electricity cut-off.
Warning: DO NOT use the machine under the environment of over damp, high temp, strong
electromagnetism interference or strong corrosion.
Notes:
1. The power supply should conform to the voltage value indicated in the instruction and keep stability
2. To avoid the interference, the sensor down-lead and power wire should be kept a distance.
