Recall factory settings
The easiest way to restore aforesaid factory settings is as follows:
• Simultaneously press buttons C, +, and – (see Fig.2)
• Then update time of the day and weekday (see chapter “Putting in operation“)
OPERATION
Continuous operation: If you want to regulate your heating system without time control, push the left slide switch (see Fig. 2, item. 2) down
to “continuous“ (sun symbol). The clock programme is thereby retained. After switching back to “time control“, the controller continues to
operate according to the predefined heating-time profile.
To turn heating off: If you want to turn off heating intentionally, push the right slide switch (see Fig. 2, item 6) down (circle symbol)
To turn heating on: If you want to turn on heating intentionally, push the right slide switch (see Fig. 2, item 6) up (circle ⁄ dot symbol).
NOTE: The LED only lights up when heat is demanded.
POWER FAILURE
In case of a power failure or interruption or short-circuit of the sensor wire, heating is switched off. The display starts blinking (see Fig. 2).
Time is shown on the display for ca. two more days. The programmed values however are retained. Set time again if necessary (see chapter
“Putting in operation“).
Attention: In case of fault, mains voltage might apply at the sensor wire.
TROUBLE SHOOTING
Diagnose
Possible cause ⁄ remedy
Heating doesn‘t work: ............................................................ Apply ⁄ check mains voltage,
check heating system, check sensor wire,
check preset temperature, check reduced-period temperature
Nothing shown on the display ⁄ controller: ...................... Apply ⁄ check mains voltage,
check device, check settings of working ⁄ resting days
Switching to heat ⁄ reduced period too early ⁄ late: ....... Press RESET, then make new settings
LED blinking: ............................................................................. Sensor not connected or defect
