Fibaro Heat Controller and Heat Activator not working properly

 Share

Question

I'm new to the Fibaro system but I'm quite disappointed. The problem is how the Heat Controller works. I have installed this heating system on one floor of the house and I also bought it on the other floor but I don't know if I will install it for these problems. I'll probably sell it because it's a disaster. I expected better software processing from these systems. Fibaro presents itself as a top on the smart market, but my disappointment is great. With such a large financial investment.

Issue # 1:
When I set all heads to OFF, sometimes the Heat Activator does not turn off because some heads still make a request for heating even when it is turned off. Check image:

Issue # 2:
When I return all the heads to the weekly plan, sometimes some head does not take over the temperature from the weekly plan but sets a different temperature I don't know how. I will solve this only by manually setting the given head to a certain temperature and then returning it and then it will take over the temperature from the weekly schedule.

 

Issue # 3:
The hysteresis on these heads works strangely.
When I have set the temperature to 21 ° C, the hysteresis is about 2 to 3 ° C, which means that when it reaches the desired temperature, then it regulates only in the range of 19 to 20 ° C and does not reach the desired temperature.

 

Issue # 4:
The graph of temperature and setpoint temperature shows values that I do not understand.
When I have set the temperature to 22 ° C, the request is drawn in a special way and shows the desired temperature of 22.5 ° C. Even when the head is off, the setpoint is displayed in the graph as a temperature that is not even in the weekly schedule.

One more question? Does anyone know what this graph is and why it can't be displayed?

Hi @marlo,

 

Got the same issue's.

Also if the heads are demanding no heat, the heat activator keeps the heater switch on, or after a reboot if I switch manualy set the heater switch to off, it will never switch on again.

I'm waiting for the next update of the HC3. If this next release has no update for the heat activator, I will contact Fibaro support, see what they have to say about this issue.

But good to know I'm not the only one with these kond of problems.

I though about using the heat activator instead of a script that I had running. However, when I looked at which heat controllers it thought should be active - it was much less reliable that a script.

I also have problems like this. Fibaro support replied that they know for problems with following schedules and wrong setpoint. I hope they understand how serious the problem is. Today I had 27C in one room, hot radiator, while set point was 22C

I suggest you report it to the support.

Hey guys,

fortunately I do not experience such a troubles as you do.

 

Just one thing I do not understand, the flag "Needs heating" goes to NO only after the temperature from the sensor goes 1C over the setpoint.

So in practice it works like 

- set point 21

- temperature 22 - boiler off

- temperature 21.9 - boiler on

 

the 1C over set point is annoying, but could be solved by changing the climate plan to reduce each setpoint by 1C (not an elegant solution, but OK)

But what I do not understand, why there is only 0.1C window for ON-OFF, I rather have it 1 or even 1.5C, as like this the boiler switching on and off every 10mins or so.

 

I do run 5.090.17 on HC3L and 4.7 on Heat Controller.

I've seen in the patch notes for 5.092.19 (beta) is mentioned "Fixes for Fibaro Heat Activator plugin." Does anyone know what those fixes relates to? I am little reluctant to try it yet as is still in beta.

 

Thanks

Unfortunately, there is no description for this "revolution in heating system" with Innovative room analysis algorithm and color control (

)

 

I have them in my home office so I can hear all day how they are opening and closing valves. I have a simple script to monitor heatingThermostatSetpoint, current temperature and status of heatRequired and it does not work so simple like this:

But the logic is a "black box".

It is php script so you need some web server.

hey @K.Drozynskior whoever has FGT-001 on charge, please tag him here.

 

Issue #1: The "Heat demand" keeps hanging. The temperature is over more then 1-5C and the heat demand is still on.

Issue #2: The "Heat Demand" hangs even when the FGT-001 is set to Off. Only manually setting the parametr OFF and the ON again will clear the "HeatDemand" flag. as @marlo

 

Issue #4: The connected Temperature sensor shows 23C (the room is max 21C IRL), the graphs shows the temperature as 20C.

Issue #5: Schedule is set to 21.5C, But Thermostat says 20, but HVAC node says 21.5, temperature is 22.5C, heat demand is off - and I can hear the valve open and the heat coming in...WHAT? I'm sitting next to the valve and I could hear it open, when should be closed due to a) schedule b) temperature

Issue #6: The Heater itself is setting to 18C. I never manualy, or via schedule set it to 18C? WTF!

WTF is "moderate regulator behaviour" there is no info about it anywhere, nor here, nor on your pages. Try search for it.

 

Request: we need to set a Hysteresis for FGT-001.

Hi.
I have already given up the heating solution according to "Heat Activator" and also according to the weekly schedule.
I threw EventRunner4 on my HC3.

Here are the rules for heating:

There is a rule for each valve: If the temperature set on the head is less than the temperature measured by the head, turn on the boiler. I solve the hysteresis individually on each head so that I enter a measured temperature of 0.5 in the rule.

 

Another rule:
If there is no movement in the room 30 min. set the heat on the head to 18 degrees. If it detects movement, set the temperature on the head to 24 degrees.

 

Last rule: It compares the set temperature with the measured temperature and if it agrees that the measured temperature is higher than the set one for all heads, it switches off the boiler.

 

I have other conditions inserted there, for example:

- at 23:59 - 4:00 do not change the temperature on the head when registering the movement
- when the average outdoor temperature is above 12 degrees, switch off the heating completely.

 

example:

sets the head to 23 degrees if the following conditions are met:

 

1, movement is disturbed

2, the switch for manual boiler shutdown is in the ON state

3, the switch for manual temperature reduction is in the ON state

4, the average outdoor temperature is less than 12 degrees. I calculate the average temperature from the internet temperature and 3 of my outdoor thermometers.

5, the head has a set temperature of 18 degrees

6, there is no time period 23: 59-4: 00

rule("_Kancel_pohyb:breached & (Vypni_kotol_MANUAL:isOn) & (Zniz_teplo_MANUAL:isOn) & (sum(PriemerTempVonku:temp)/size(PriemerTempVonku) <= 12) & (_Kancel_hlavica_:heatingThermostatSetpoint == 18) 
& 04:00..23:59 => _Kancel_hlavica_:heatingThermostatSetpoint = 23")

 

*************

This rule melts the head to a temperature of 18 degrees if not 30 minutes. movement in the room

 

1, counts 30min. from the time when the motion sensor went into intact mode

2, the head has a set temperature of 23 degrees

3, the average outdoor temperature is less than 12 degrees. I calculate the average temperature from the internet temperature and 3 of my outdoor thermometers.

 

rule("trueFor(00:30,_Kancel_pohyb:safe) & (_Kancel_hlavica_:heatingThermostatSetpoint == 23) & (sum(PriemerTempVonku:temp)/size(PriemerTempVonku) <= 12) => _Kancel_hlavica_:heatingThermostatSetpoint = 18") 

 

*************

This rule sends a request every 5 minutes to turn on the boiler if the following conditions are met:

1, the switch for manual boiler shutdown is in the ON state

2, the average outdoor temperature is less than 12 degrees. I calculate the average temperature from the internet temperature and 3 of my outdoor thermometers.

3, the temperature is set on the head - 1 (hysteresis) is higher than the measured room temperature.

 

at the end it lists the set and measured temperatures in the log

 

rule("@@00:05:00 & (Vypni_kotol_MANUAL:isOn) & (sum(PriemerTempVonku:temp)/size(PriemerTempVonku) <= 12) & (_Kancel_hlavica_:heatingThermostatSetpoint-1 > (_Kancel_Temperature:value)) => _Kotol_:on; log('Zapínam kotol ********************Teploty v KANCELÁRII sú:Teplo v izbe=%s %s %s',_Kancel_Temperature:value,'Teplo požadované=',_Kancel_hlavica_:heatingThermostatSetpoint)")

 

*************

This rule switches off the boiler when it is heated everywhere.

 

1, checks the conditions every 2 minutes

2, the switch for manual boiler shutdown is in the ON state

3, the temperature set on the head is less than or equal to the measured temperature (4 headers are used in the rule)

 

at the end it will write to the log: I will switch off the boiler ...... "hurááá" .... the temperatures are according to the requirements

 

rule("@@00:02:00 & (_Kotol_:isOn) & (_Kancel_hlavica_:heatingThermostatSetpoint <= (_Kancel_Temperature:value)) & (_Dielna_hlavica_:heatingThermostatSetpoint <= (_Dielna_Hlavica_Temp:value)) & (_Detska_Hlavica1_:heatingThermostatSetpoint <= (_Detska_Hlavica1_Temp_:value)) & (_Detska_Hlavica2_:heatingThermostatSetpoint <= (_Detska_Hlavica2_Temp_:value))  => _Kotol_:off; log('Vypínam kotol ********************  H U R A A A A A......Teploty sú podla požiadaviek')")
