PulseStation and heating

Hereby a short article about one of our users (Julien) and how he configured his heating.
Many thanks to him for writing this tutorial

There are 2 ways of working :
A/ Using an advised temperature
+ Only the modes stop / comfort are used -> one module can control 2 zones (connection in the electrical panel as an example)
+ More precise then the thermostat of the radiator
– Requires getting the room temperature -> needs a temperature sensor

B/ Using the internal thermostat using the different modes of the radiator (stop, comfort, eco, frost protection)
– 1 module per radiator or zone (in case of connection in the electrical panel)
+ No need for an additional temperature sensor

All this can either follow a predefined calendar or set manually.

1/ Choice of modules and connections:
I will not go in detail above, many tutorials are available in lines like this: http://www.planete-domotique.com/blog/2012/01/05/piloter-un-radiateur-grace-a-son-fil-pilote/
PersonallyI have chosen for the modules bi-relais of Fibaro (FGS221) for following reasons:
– small size
– possibility to operate the 4 modes of the radiators (I have purchased one per radiator)

2/ Integration of the modules in PulseStation
The modules FGS221 are easily recognized as 2 interrupters  (1 per relai).

3/ Configuration PulseStation
Personally I have chosen for a complete autonomous system (no action required from my end, so I have not invested time in properly configuring the panels for the different manual modes of the radiators, but that is very simple to do using a “list of values”).

Thermostat using recommended temperature in my living room :

The recommended value is set using following scene :

When motion is detected (someone is in the living room), we put the desired temperature on 21 launching a timer of 15 minutes after which the temperature decreases again to 18°C (there is nobody there anymore°.

A second scene takes care of the interactions with the radiators based on certain conditions :

If the temperature outside is below 15°C and I am not on holiday:
Between 00h and 5h, I put the temperature on 15°C.
  If the temperature if the measured temperature is below the desired temperature:
	I start heating
  Otherwise
	I turn off the radiators.
Otherwise
I turn off the radiators.

Using the different modes of the radiators

The radiators in my rooms are activated based on the hour and certain criteria:

If the outside temperatire is below or equal to 16°C and I am not on holiday,
	If it is between 8h and 18h,
		If it is between 13h and 15h and the guard mode is active 
			I activate the comfort mode (for my son's nap)
		Otherwise
			I activate the Eco mode 
	Otherwise
		I activate the comfort mode (I let the radiators heat during the night)
Otherwise
	I turn off the radiators

The modules FGS221 are the double value panels (True +False => Stop mode). 
Cf. scenes above it, 
it is 18°C with me and the default modes are active -> the radiators are turned off.

Todo:
The use of the desired temperature is more accurate, I work on the establishment of a “low cost” temperature sensor, connected to a raspberry pi that will monitor the temperature of my rooms PulseStation.
