4 Chapter 1. Overview REMOTE TEMPERATURE CONTROLLER USER S GUIDE 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 is used as the of temperature readings, timing and the s, 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 and timer, it s can be widely used in various applications requiring temperature control and time control.

Ti>TH: relay closed; Ti<TH: relay open. External cooling devices are recommended. Take the upper and lower limits as the threshold and use hysteresis control. Ti>TH: relay closed; Ti<TL: relay open. Take the upper and lower limits as the threshold and use hysteresis control. Ti>TH: relay open; Ti<TL: relay closed. Utilize Time Relay mode. Before the set time: relay open; time up: relay closed. Regularly open the external devices. Utilize Time Relay mode. Before the set time: relay close; time up: relay open. Regularly close the external devices Sure Electronics Inc.

Upper limit The upper limit should be or higher than the lower limit. The limits should be within the Lower limit DS18B20 s measuring range of (-55 to +125 )/(-67 to +257 ) Pressing any of the four keys / / / / / can switch the modes. Timing Working mode To any operation, the timing should be within 1min to 99min. 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 mod Sure Electronics Inc.

Instead of entering other working modes, the panel will normally temperature after the operation of turning off the and then turning on the 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. 2. The panel will temperature after the timing of MOD5/MOD6 ends. 3. All the s (upper limit, lower limit, /, 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 ed have the same unit. 5. If you don t press OK to exit the before the power drops or is turned off, the current won t be saved. 6. If the is turned off during and then turned on, the panel meter will normally 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, unplug or plug the DS18B20 will cause temporary wrong (85 /185 ) but without other affect.
