1. MODEL : EDF-102 SERIES 1. APPLICATION The EDF-102 thermostat is designed to provide temperature control of heating or cooling systems in villas, hotels and building. It can be used as part of a system in conjunction with boilers, thermal actuators, and zone valves. The unit with key pads and large LCD display is ideal for customers who want reliable precise temperature control from a modern looking, simple to program and easy to use products..Users can control 3-fan speed,, by sliding the key pad H.M.L manually. 2. FEATURES ■ The current temperature and heat/cool are to be displayed on LCD window. ■ The set temperature is displayed when setting and it will be changed to the current temperature in 3 seconds. ■ Manual 3-fan speed control ■ Heat/Cool changeover switch ■ It can control an actuator and a fan motor. ■ Wall mounted type 3. SPECIFICATION ■ Rated Voltage : AC110V/220V/50~60 Hz ■ Temperature Range : 5 ℃ ~ 70 ℃ ■ Temperature Accuracy : 1.5 ℃ Max ■ ON-OFF differential : 1 ℃ Max. ■ Temperature display and setting unit: 0.5 ℃ /STEP ■ Fan speed: 3 stage High, Medium, Low ■ Load Current : 1A/220V ■ Case material : ABS ROOM THERMOSTAT FOR FANCOIL UNIT

2. 4. HOW TO USE ■ POWER The electric power is OFF when the slide switch is positioned on the left side. The green power lamp is ON when the slide switch is pushed to the 2 nd stage and the initial fan speed is High. ■ TO SET THE DESIRED TEMPERATURE 1) The previously set temperature is displayed once on LCD window when pressing ▲ (+) or ▼ (-) button. 2) Press ▲ (+) or ▼ (-) button to set the temperature as desired. 3) The set temperature is saved in 5 seconds and the current temperature is displayed on LCD window again. ■ FAN SPEED The bottom slide switch can control the fan speed H →M→ L. ■ HEAT/COOL CHANGEOVER Users should change the heat/cool switch on the right side to et the heat/cool mode. (H : Heating C: Cooling) Heating Operation 1) Set the heating mode (H). 2) When the set temperature becomes higher than the current temperature the red LED is ON and a symbol is displayed on LCD window. 3) When the current temperature becomes lower than the set temperature the red LED is OFF and the symbol is disappeared. Cooling Operation 1) Set the cooling mode (C). 2) When the set temperature becomes lower than the current temperature the red LED is ON and a symbol is displayed on LCD window. 3) When the current temperature becomes lower than the set temperature the red LED is OFF and the symbol is disappeared. ☞ Users should set the changeover switch to the heating mode in winter and cooling mode in summer.

POWER & FAN SPEED SWITCH Through this procedure users can set the maximum / minimum temperatures or compensate the temperature difference. Adjustable functions : OP1 - is to adjust the maximum temperature( 27~70 ℃. 81~158F) : OP2 - is to adjust the minimum temperature(5~26 ℃. 41~79F) : OP3 - is to compensate the current temperature.( -2 ~+2 ℃ ) 1) Turn off the power switch. 2) Press ▲ (+) and ▼ (-) buttons simultaneously for 1.5 seconds. Then, OP1 is displayed. 3) Press ▲ (+) button. Then OP1~OP3 is displayed in sequence. 4) Press ▼ (-) button to choose the desired functions 7. ERROR SIGN 1) Er1 : Sensor disconnection 2) Er2 : Sensor short
