Ringder DTC-120 User Manual

DIGITAL DIMMING THERMOSTAT DAY & NIGHT + TIMER
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.
2. Using real-time clock to control the light, simulating the day and night as real environment.

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
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
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
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.
