Chapter 1. Overview
1.1 Overview
Thanks for using this remote temperature controller by Sure Electronics. This product is
populated with a high performance 8-bit PIC16F690 as the main chip, 7-segment LED
display is used as the display of temperature readings, timing and the settings, a relay to
control the external heating or cooling devices, a IR receiver receiving signals from the
7-key battery-powered remote control. It utilizes an external high precision water-proof
digital DS18B20 probe as the temperature sensor. Used together with a 7-key remote
control which is used to set the panel meter over the working modes, upper and lowers
limits of temperature value, °F /°C display and timer, it’s can be widely used in various
applications requiring temperature control and time control.

Working Mode Description
Display current temperature measured by DS18B20 with relay not
considered.
MOD0
Take the upper limit TH as the threshold. Ti>TH: relay open; Ti<TH:
relay closed. External heating devices are recommended.
MOD1
Take the upper limit TH as the threshold. Ti>TH: relay closed; Ti<TH:
relay open. External cooling devices are recommended.
MOD2
Take the upper and lower limits as the threshold and use hysteresis
control. Ti>TH: relay closed; Ti<TL: relay open.
MOD3
Take the upper and lower limits as the threshold and use hysteresis
control. Ti>TH: relay open; Ti<TL: relay closed.
MOD4
Utilize Time Relay mode. Before the set time: relay open; time up:
relay closed. Regularly open the external devices.
MOD5
Utilize Time Relay mode. Before the set time: relay close; time up:
relay open. Regularly close the external devices.
MOD6

2.3 Description of The Remote Control’s Keys
The 7-key user-definable infrared remote control utilizes NEC IR encoding mode and
integrates SC6122 IC as the remote control transmitter which utilizes CMOS Technology
specially designed for use on infrared remote control applications

(-55℃to +125℃)/(-67℉to
+257℉)

Continuously pressing one key,
the working mode will switch in
a cycle from mod0 to mod6 or
from mod6 to mod0. For
example, the current working
mode is mod0. Continuously
pressing key2(+), the working
mode will switch in a cycle of
mod0→mod1→mod2→mod3→
mod4→mod5→mod6→mod0.

In these modes, after the
operation of turning off the display
and then turning on the display,
the panel will normally display
temperature.
Note:
1. Instead of entering other working modes, the panel will normally display
temperature after the operation of turning off the display and then turning on the
display or the operation of repowering the panel after the power drops. Before
pressing “OK” to activate the working mode, you’re suggested to use “Set” key to
check the setting.
2. The panel will display temperature after the timing of MOD5/MOD6 ends.
3. All the settings (upper limit, lower limit, ℃/℉display, timing and working mode)
will be saved in EEPROM after power drops.
4. The upper and lower limits will correspondingly transact after the switching of ℃/
℉. The limits and the temperature readings displayed have the same unit.
5. If you don’t press “OK” to exit the setting before the power drops or display is
turned off, the current setting won’t be saved.
6. If the display is turned off during setting and then turned on, the panel meter will
normally display temperature readings or timing.
7. The timing will pause when you press any key. Do not press any key during timing,
or the timing won’t be accurate.
8. During normal temperature display, unplug or plug the DS18B20 will cause
temporary wrong display (85℃/185℉) but without other affect.
