Type of Radiators with Thermostatic Valves (Winter)

alt_text

The type radiators with thermostatic valves is suitable for a home heated by wall-mounted radiators controlled by smart thermostatic valves, connected to a heat pump that produces technical hot water.

A house with various possible setups is represented by the diagram, in particular there are:

  • no. 3 rooms (Room 1 - Room 3)
  • no. 4 Radiators (R1 - R4)
  • no. 3 Thermostats / Smart temperature sensors (T1 - T3)
  • no. 4 smart thermostatic valves (V1 - V4)

Each room schematizes a possible different setup that can be used as an example to adapt to your case, below is an explanation of the configuration and how it must be implemented on the Home Assistant in order to use Homsai correctly.

Room 1 (one Radiator and one Zone Thermostat)​

Room 1 contains a radiator (R1) connected to a smart thermostatic valve (V1).

The house has a single zone thermostat (T2) which manages the air conditioning, connected directly to the heat pump by means of consent. When the thermostat T2 requests heat, the following are automatically activated:

  • Heat pump
  • Recirculation pump

In order to convey hot water towards the radiators (R1, R2, R3, R4).

The thermostatic valves (V1 - V4) will eventually take care of enabling the dedicated portion of the circuit.

In this case Home Assistant must contain:

  • An area representing the room “Room 1”, e.g. room_1
  • A climate entity which represents the thermostatic valve V1, and has the area room_1 (e.g. climate.v1)
  • A sensor entity which represents the current temperature of the thermostatic valve V1, if not natively present, can be obtained by defining the template entity on configuration.yaml, and has the room_1 area (e.g.sensor.v1_temperature`)
  • A climate entity disabled representing thermostat T2 (e.g. climate.t2)
  • A switch entity that represents the implementation of the heat request of the thermostat T2, if not natively present can be obtained by defining the template entity on configuration.yaml (e.g. switch .t2_on)

NB. The climate.t2 entity must be present but disabled because the thermostat behavior is overridden by the thermostatic valve (climate.v1). Of climate.t2 it is only necessary to extrapolate switch.t2_on.

In this way Homsai is able to create and optimize the room "Room 1" correctly.

Room 2 (one Radiator and one Thermostat)​

Room 2 contains a radiator (R2) connected to a smart thermostatic valve (V2) and a smart thermostat dedicated to the room (T1).

When the thermostat T1 requests heat, the following are automatically activated:

  • Heat pump
  • Recirculation pump

In order to convey hot water upstream of radiator R2. The circuit is actually opened by the smart V2 thermostatic valve.

In this case Home Assistant must contain:

  • An area which represents Room 2, e.g. room_2
  • A climate entity which represents the thermostatic valve V2, and has the area room_2 (e.g. climate.v2)
  • A sensor entity which represents the current temperature of the thermostatic valve V2, if not natively present, can be obtained by defining the template entity on configuration.yaml, and has the room_2 area (e.g. sensor.v2_temperature)
  • A climate entity disabled which represents the thermostat T1, and has the area room_2 (e.g. climate.t1`)
  • A sensor entity which represents the current temperature detected by the thermostat T1, if not natively present, can be obtained by defining the template entity on configuration.yaml, and has the area room_2 (e.g. sensor.t1_temperature)
  • A switch entity that represents the implementation of the heat request of the thermostat T1, if not natively present can be obtained by defining the template entity on configuration.yaml (e.g. switch .t1_on)

NB. The climate.t1 entity must be present but disabled because the thermostat behavior is overridden by the thermostatic valve (climate.v2). Of climate.t1 it is only necessary to extrapolate switch.t1_on and sensor.t1_temperature.

In this way Homsai is able to create and optimize the room "Room 2" correctly

Room 3 (more than one Radiator and/or more than one Thermostat)​

The room 3 contains two radiators (R3 and R4) connected to the smart thermostatic valves (V3 and V4), a smart thermostat dedicated to the room (T2) and a smart temperature/humidity sensor (T3).

When the thermostat T2 requests heat, the following are automatically activated:

  • Heat pump
  • Recirculation pump

In order to convey hot water upstream of radiators R3 and R4. The effective opening of the circuit is carried out by the smart thermostatic valves V3 and V4.

In this case Home Assistant must contain:

  • An area which represents the room “Room 3”, e.g. room_3
  • A climate entity which represents the thermostatic valve V3, and has the area room_3 (e.g. climate.v3)
  • A sensor entity which represents the current temperature of the thermostatic valve V3, if not natively present, can be obtained by defining the template entity on configuration.yaml, and has the room_3 area (e.g. sensor.v3_temperature)
  • A climate entity which represents the thermostatic valve V4, and has room_3 as its area (e.g. climate.v4)
  • A sensor entity which represents the current temperature of the V4 thermostatic valve, if not natively present, can be obtained by defining the template entity on configuration.yaml, and has the room_3 area (e.g. sensor.v4_temperature)
  • A climate entity disabled which represents the *thermostat T2**, and has the area room_3 (e.g. climate.t2)
  • A sensor entity which represents the current temperature detected by the thermostat T2, if not natively present, can be obtained by defining the template entity on configuration.yaml, and has the area room_3 (e.g. sensor.t2_temperature)
  • A switch entity representing the actuation of the heat request of the thermostat T2, if not natively present can be obtained by defining the template entity on configuration.yaml (e.g. switch .t2_on)
  • A sensor entity which represents the *current temperature of the T3 smart temperature/humidity sensor**, and has the area room_3 (e.g. sensor.t3_temperature)

NB. The climate.t2 entity must be present but disabled because the thermostat behavior is overridden by the thermostatic valves (climate.v3 and climate.v4). Of climate.t2 it is only necessary to extrapolate switch.t2_on and sensor.t2_temperature.

In this way Homsai is able to create and optimize the "Room 3" room correctly.
