Energy manager Basic

The Kermi energy manager is used to increase the use of self-generated electricity with a solar panel system or other systems such as a combined heat and power unit:

With the Kermi energy manager, in association with the temperature module, you can increases own consumption from solar panel systems in a simple and cost-effective way. If too much electrical power is fed into the grid, then for example the heat pump is activated and generates heat in advance which is then stored in the domestic water heating area.

Characteristics:

  • High own consumption proportion of self-generated electricity
  • Energy cost savings for heating and domestic water heating
  • Yields even on cold/cloudy days
  • Storing energy in the form of super-heating in the domestic water heating area
  • Data from an energy meter (digital electric meter) can be read in via an S0 interface. In this way, the percentage of self-generated electrical energy that is used in the building and the percentage that is fed into the grid can be recorded.
    If more electricity is fed into the grid than the desired amount, the heat pump, for instance, is activated and generates heat for storage in the buffer storage tank.
  • For installation on a top-hat rail
  • Optional temperature module to connect up heat pumps without a corresponding input

Functional principle energy manager Pro

The energy manager Pro is connected via an SO signal to the energy counter at the grid transfer point. The S0 signal states what quantity of electrical output is consumed or fed into the public grid. Corresponding thresholds can be set on the energy manager using software. If the corresponding threshold is exceeded, then the contact closes and the heat pump or another consumer is activated.

Configuration/Settings

  • S0 pulse rate (Pul./kWh)
  • Switch-on threshold with delay and lag
  • Switch-off threshold with delay and lag

Energy acquisition

  • S0 pulses are made available by the counter and recorded by the energy manager
  • Pulses per time unit = Gauge for the output currently available at the grid transfer point

Control of the downstream unit

With the potential-free contact, a consumer can either be controlled directly (output side), via a digital input on the controller, or via the temperature module.

Functional principle temperature module (optional)

The temperature module can be used for heat pumps without a corresponding input for an external requirement. The temperature module is integrated between a domestic hot water sensor in the storage tank and the heat pump controller. If the threshold value on the energy manager is exceeded, then the characteristic line of the temperature sensor is affected and the temperature value is reduced. The heat pump then heats the storage tanks to a higher temperature level than in normal operation.

Parameter setting / fine setting

  • Select type of sensor via dip switch
  • Balance out tolerances via potentiometers

Linking into the system

  • Control via energy manager
  • Coupling link between sensor and WP controller

Energy Manager Pro

With the Kermi Pro energy manager with an integrated temperature module, you can increase your own consumption from solar panel systems in a simple and cost-effective way. If excess electrical power is fed into the grid, then for example the heat pump and/or other heat sources can be activated. Additional heat generated is stored in the storage unit (Power-to-Heat).

Characteristics:

  • High own consumption proportion of self-generated electricity
  • Energy cost savings for heating and domestic water heating
  • Storing energy in the form of super-heating in the domestic water heating area

Advantages of energy manager "Pro" in comparison to "Basic"

  • integrated temperature module
  • 3 additional relay outputs
  • simple parameter settings
  • extended logging function
  • intelligent switching algorithms  

Functional principle energy manager Pro

The energy manager Pro is connected via an SO signal to the energy counter at the grid transfer point. The S0 signal states what quantity of electrical output is consumed or fed into the public grid. Corresponding thresholds can be set on the energy manager Pro using software. If the corresponding threshold is exceeded, then the contacts close one after the other (depending on the surplus energy) and the heat pump and/or other consumers are activated.

Configuration/Settings

  • S0 pulse rate (Pul./kWh)
  • Power consumption of consumers

Energy acquisition

  • S0 pulses are made available by the counter and recorded by the energy manager
  • Pulses per time unit = Gauge for the output currently available at the grid transfer point

Control of the downstream unit

With the potential-free contact, a consumer can either be controlled directly (output side) or via a digital input on the controller.
Using the output A1, the characteristic curve of the temperature sensor in the domestic water area can be influenced. 

Functional principle temperature module (integrated)

The temperature module can be used for heat pumps without a corresponding input for an external requirement. The temperature module is integrated between a domestic hot water sensor in the storage tank and the heat pump controller. If the threshold value on the energy manager is exceeded, then the characteristic line of the temperature sensor is affected and the transmitted temperature value is reduced. The heat pump then heats the storage tanks to a higher temperature level than in normal operation.

Parameter setting / fine setting

  • Select type of sensor via dip switch
  • Balance out tolerances via potentiometers

Linking into the system

  • Control via energy manager
  • Coupling link between sensor and WP controller

SG-Ready

With the energy manager, the Kermi heat pumps meet the requirements of the SG ready label. (x-change dynamic is already SG-Ready without additional accessories)

Energy suppliers can offer special electricity tariffs with reference to SmartGrid, however at the moment that is only possible in a few selected regions in Germany.
With this, the energy supplier want to control the electricity consumers according to the grid utilisation. With the continuously growing section of electricity produced from renewable energy, there are often fluctuations in the electricity grid.

To ensure efficient and reliable operation of the electricity grid, the energy supplier can for example start heat pumps operating when they are expecting peak loads or if there is insufficient supply, block them for a defined period of time.

The following switching states are possible:

  • 00: operation prohibited (= EVU lock contact)
  • 01: Normal operation
  • 10: Start-up recommendation
  • 11: Start-up obligation (where the system limits allow this)
