Again, I can connect the positive reviews I only have 5 installed thermostats for floor heating and replace bi-metal dial thermostats. After checking the heating system and the thermostat control initially had all neutral are connected in my case, since these were previously only connected to the neutral conductors of thermostats without the regulator. After that I could simply replace the old controller, connected conductor, neutral and control line, finished. The programming turned out to be very easy out, using the supplied German manual also no problem. The lighting unless permanently switched goes, after 5 seconds, not after 15 sec. The timed control one must only times "understand", you can adjust 6 programs from which time the set temperature to be reached (eg 22 ° from 06:00 and from 10:00 only 19 °, then again from 16:00 22 °, etc.). The displayed temperature can be adjusted, which should be conducted by an additional thermometer near the thermostat in the wall. So you can at any time read the temperature of the room, and then true. In the nursery, I have held up a thermometer in the room and the room entrance (about 3 meters from the center of the room to the hall way) adapted the built-in thermostat of the room temperature in the other rooms I have the thermometer -a Wetterstation- next the thermostat setting asked to hernehmen this as a "basis" for the room temperature can. Then the thermostat is set according to the desired temperature, ready. With a hysteresis of 0.5 ° C this switch now drops below a temperature and at the temperature + 0.5 ° pass out again, resulting in a total constant room temperature for a row! (Eg 21.5 ° set, heating opens at 21.4 ° and 22.0 ° and closes at reopens only at 21.4 ° which has a room temperature of 21.7 ° to always participate in our FBH result). That was impossible with the bi-metal parts! Since one has nen Wolf turned that to make reasonably constant temperatures. In the bathroom, the timer comes into play, at 04:00 clock turn on the thermostat and "wants" 24 °, but since we leave at 06:40 clock the house, the thermostat is at 07:00 clock down to 19 °. On weekends (circuit 5 + 2) then the thermostat opens at 06:00 clock and closes again at 10:00 clock, after the heating does not have to unnecessarily verballern energy. The remaining thermostats are controlled manually, the heating system IS BASED ON 22:00 bis 04:00 clock in the night setback ... In addition, the room thermostat is used in the hallway as a "night light", because we are there, the lighting to continuous operation. After several simulated power outages all room thermostats go back to their previous function returns, as it should be, the time is right after that again! Even if the watch a month within approximately 10 minutes (which I can not confirm), so not really itches but someone, and the setting on all units is ne thing 2 minutes at the weekend! All in all you get for little money really a huge energy saving, no hassle of turning wheel at a reasonable temperature hinzubekommen, modern design with digital display, something that affects the room temperature for control freaks and it's really easy to install! For me a real profit, have the part my neighbors also recommended and recommend it to all others that wish to operate an energy-optimized heating. The long-term report is there next winter :-)
Addendum 12.05.2013: In a review I read that the clocks 10 minutes in the month vary, after exactly one month I must again speak to! I have from 12:04. until today, a deviation of 1 minute and 20 second lead time determined what the clock of my super expensive microwave also creates. On an annual basis would be a deviation of 16 minutes and I wonder if it really takes serious proportions when my thermostat really only 1/4 hour to the programmed time opens (if I never nachstelle the watch!)? As before, these super parts do their job and we enjoy the consistent, energy-saving temperature in all rooms without always having to roll over it. I had only once via reference thermometer adjust the temperature in order to obtain more accurate values, once had to settle everything ...
