The installation was very simple. A firm grip and relatively good workmanship. Without tool, the controller is mounted quickly!
2. Operation:
The operation is difficult to start with but this is right after the 2nd or 3rd time programming no problem. The backlight goes out as fast and does not bother you does not have to necessarily night programming.
3. Function:
In the beginning I noticed that these devices a relatively loud noise when have these rules. During the day the Okay is only at night disturbs it.
It is important here ENSURE how high the switching temperature. After factory setting, this is 0.5 ° C.
example
22 ° C Set
22 ° C is
So the valve opens
22 ° C Set
22.5 ° C
Now the valve closes as setpoint temperature + switching temperature is reached.
But as 0.5 ° C have flown in space very quickly opens and closes the valve every half hour.
Taking the temperature of eg 2.0 ° C, it no longer switches only every 2 to 3 hours and at night.
Conclusion:
Who is not necessarily the big purse on hand, has for it's great!
You simply can not ask for Mercedes for the price.
It is also recommended to purchase a device and try just once.
From me gets the Electronic Thermostat "Heizlux HK55" 4 stars for value!
