Re: HmIP-FALMOT-C12 strange behaviour

Hi, It is a "best way" but for systems where you always have a hot water. When using individual boilers the energy needed to start it up, heat the systems is lost if FALMOT is starting it for 30 seconds... I have such intervals... completely useless. It cycling until the temperature drops more than ...

Re: Minimum valve opening value for individual TRV

I think the EQ3 should add the possibility to manually override the opening of each valves (all e-trvs and also fallmot-c12). It looks like the auto adaptation to the valves is not working as expected. Adding an option to set the minimum valve opening will solve the problem. Normally we have 0% to 1...

HmIP-FALMOT-C12 strange behaviour

Hello, I'm using HmIP-FALMOT-C12 to control my floor heating with HmIP-WTH-2 wall thermostats and found some strange behaviour of the valves. If the room temperature is around +/- 0,1 degree from the set point temperature it is opening the valve (and starting the boiler) from few seconds to max two ...

Re: HmIP-WTH-2 to HmIP-eTRV-C connection

Create a group - HmIP-Heating Control. It will make all the connection automatically.

Re: Smart heating - request for advice

Hi, I'm using two scripts one for underfloor heating and one for radiators. Underfloor heating triggers: ufh.png And the script: string deviceid; integer valveopen = 0; foreach(deviceid, dom.GetObject(ID_DEVICES).EnumUsedIDs()) { var device = dom.GetObject(deviceid); if( ("HmIP-FALMOT-C12" == device...

Re: Smart heating - request for advice

Hi, I'm currently playing the same game but with different boiler and I will advise first to use CCU3 instead of Access Point. The way how the homematic algorithms are controlling the valve opening is a little bit strange for me as it is using some small opening values which are not optimal for heat...

Re: Minimum valve opening value for individual TRV

Ok seems also logic - sorry if I was wrong I think the documentation should be more precise. As here we are trying to find how the offset parameter is working by some experiments. Also for me the Data Points are unclear - as for the FALMOT there are same configuration Data Points in the documentati...

Re: Minimum valve opening value for individual TRV

As I understand your valve normally has a range from 0 - 100%. When you set the offset to e.g. 20 - the new "0" will be open with "20". So next time the valve will heat up and than after a while stop heating it will return to "0"what will be in reality the offset "20". The App of course will show y...

HmIP-FALMOT-C12 - heat demand singnal

Hi, I'm currently using a HmIP-ETRV-2 valves for radiators with WTH2 wall thermostats and just installed the HmIP-FALMOT-C12 to control the floor heating zones also with WTH2. What I'm trying to do now is to create a boiler controller that will turn it on if there will be heating demand. The first t...
