Parameter remarks

Nr. Remark
1When differential is 0 the fan does not restart.
2When duration is 0 there is no time limit otherwise cycle is stopped by temperature or time whichever is first.
3The low temperature differential is fixed, and alarm status stops at 0.2 °C above the set point.
4The high temperature differential is fixed, and alarm status stops at 0.2 °C under the set point.
5The minus sign on display ("-") signals that output is going to start after a delay.

How to ...

How to ... Function
Switch between on and stand-by.Keep pressed B3 button, to activate and deactivate stand-by. In stand-by every output is disabled except light, leds from L1 to L6 blink, timers continue to count.
Program the menu.Keep pressed B6 to enter the menu. Navigate up and down with B2 and B5. Select the submenu by B6. Change the parameter by B2 and B5, press B6 to confirm, or B4 to go back without saving. The changes will have effect after the exit from programming pressing B4 repeatedly. Press B1 to exit immediately without saving any parameter.
Show or change temperature set.Press shortly B6 - the display shows the current set point - change it by B2 and B5, and confirm it by B6. As alternative, enter the menu program as explained above, modify the parameter _t0, then confirm it.
Start, pause, or restart the cycle.Press shortly the B3 button to start, pause, or restart the cycle. When the evaporator fans are stopped, the display blinks.
Abort the cycle.Press shortly the B1 button to terminate the cycle.
