Operation diagram

Time and time interval setting

Time interval programming

The factory default temperature value of time interval 3 and 4 are the same as period 2,please modify default temperature when it’s necessary.
Setting temperature is“00”, this time interval is shutdown.
View out temperature value (floor temperature)
(1)Touch screen version: when internal control temperature and external limit temperature(high temperature protection),under power on state, press time key not move first, then press on/off key together to switch and view external temperature (this time measure temperature display zone displays OUT TEMP temperature value),press time key to display room temperature;

Advanced Setting(suggestion: operated by technician)

Note: hysteresis (return temperature) description: the factory default of external sensor limit temperature(OSV) set as 42℃, external sensor limit temperature hysteresis(dIF) set as 2,when temperature up to 44℃,relay stop output, when temperature drops to 40℃,relay output again and heating.(operation when room temperature lower than setting temperature)

Sensor fault hint

Please select internal, external sensor working mode correctly. If it is choose wrong or sensor is fault (breakdown),LCD interface will display “Err” ,temperature controller stops heating until fault is eliminated. Special Hint :installation cable

Please select: water heating selects 1.5-2.5mm2 rigid line; electric heating select above 2.5mm2 rigid line.

Power wiring diagram

Note: 3 & 4 connect with power, 5 & 6 connect with gas boiler,1& 2 connect with thermal actuator, please do not connect 1&2 to gas boiler,If you connect it wrongly, there will be Short circuit.
