6. Children lock to prevent misoperation by children. 7. Data memory when power is off. 8. Holiday mode make you enjoy more comfortable temperature in holiday. 9. The visible thickness above the wall is only 15mm 86mm Technical parameters Power source: 90-240VAC, 50/60Hz Display accuracy: +/-0.5°C Hysteresis: adjustable from 0.5-2.5°C. (Minimum hysteresis is +/-0.5°C, it means when you set temperature at 23°C, it turns on boiler when room temp. drops to 22.5°C, it turns off boiler when room temp. rises to 23.5°C.) Probe sensor::NTC(10k)1% Contact capacity::3A/250V Working environment temperature::0~90°C Range of temperature adjustment::5~35°C Range of temperature display::0~40°C Insulating condition: Normal environment Running program: Set per 1 week as a cycle Output: Switch relay Installation: Wall mounted or on battery seat Size(mm):86*86*27 Display size : 64*64mm Wiring diagram 3 ways of wring 1. Control gas boiler only. Connect 5 & 6 to gas boiler 5 6 is dry contact no voltage output, connect 3 & 4 to power supply 2 Control gas boiler thermal actuator at same time Connect 5 6 to gas boiler connect 1 & 2 to thermal actuator connect 3 4 to gas boiler 3 Control thermal actuator only. Connect 1&2 to thermal actuator connect 3 4 to power supply Warning!! Please do NOT connect 1&2 to gas boilerIf you connect it wrongly there will cause Short circuit our gas boiler board will be damaged. FAQ Q: What is minimum hysteresis A: +/-0.5°C.
