Fully automatic hydronic balancing

The EAZY Base 3 Balance base station is the intelligent single room control of the future for a maximum comfort and energy efficiency for surface temperature control.

The EAZY Base 3 Balance with integrated TÜV certified “automatic hydronic balancing” carries out balancing completely automatically and without the connection of additional hardware. Furthermore, the EAZY Base 3 Balance also offers a cooling function by inverting the input signals of standard heating controllers. Commercially available 230 V heating controllers can be connected. The system identifies the requirements of the controller and adjusts automatically. The commercially available thermal actuators in 230 V design are used for controlling. The system meets the requirements of the EnEV (German Energy Saving Regulations) and of the BAFA (Federal Office of Economics and Export Control) and is therefore eligible. With the TÜV certificate it is at least of the same value as the manual hydronic balancing.

FAQ

You can find a summary of all frequently asked questions and information on the wiring centre EAZY Base 3 Balance here:

Does the EAZY Base 3 Balance base station replaces the traditional manual hydronic balancing?

Yes! The EAZY Base 3 Balance system fulfils the requirements of the EnEV (German Energy Saving Regulations) and of the BAFA (Federal Office of Economics and Export Control) and is therefore eligible. According to the TÜV certificate it is at least the same as the manual hydronic balancing.

How does the hydronic balancing work?

The heat requirements of the different circuits are included in the algorithm which uniformly distributes the opening times of the thermal actuators over a firmly defined period. Thus, sufficient heat is supplied to all heating circuit also in systems which are NOT hydronically balanced. This method only works for inertial heating systems as surface heating systems.

Is it possible to use any controllers with the base station?

All commercially available controllers are compatible with the Alpha direct Balance system.

Does the base station have a cooling function?

Additional switching components are provided in the base station of the EAZY Base 3 Balance system. They allow an inverting of the controller signals and a transmission to the thermal actuators. This feature makes an operation of the EAZY Base 3 Balance also for cooling possible.

Is the Base able to cool with any controller?

The cooling function is realised by the base station. Commercially available heating controllers can be used for both applications (heating/cooling).

Is it possible that the EAZY Base 3 Balance opens the thermostat valve regularly in summer to avoid a sticking?

The EAZY Base 3 Balance system includes a valve protection function which activates the valves after a certain time of inactivity independently from the season.

Is it necessary to install balancing valves or other balancing devices in the distribution network?

Depending on the local circumstances, it may be necessary to use balancing valves. The EAZY Base 3 Balance system balances the heating loops of one distribution beam and is not appropriate for a balancing of several distribution beams among each other.

Are flow indicators still necessary in combination with the EAZY Base 3 Balance system?

Principally no flow meters are not necessary when the EAZY Base 3 Balance system is used. We recommend maintaining the current setting (as it exists) or to set all flow limiters to full flow.

Is it necessary to initialise or calibrate the EAZY Base 3 Balance?

No. The system runs completely autonomously. No initialisation or calibration is necessary.

What happens while commissioning the base station?

The algorithm analysis the outputs of the controller during the first 30 minutes after connection of the base station. After detection of a cycle, this heating zone participates in the load distribution. If no cycle is detected, the heating zone does not participate in the load distribution and the signal of the controller is transmitted 1:1. The controller outputs are further analysed and the heating zones participates in the load distribution when a cycle is detected.

Is it possible to bridge the heating zones?

It is principally not planned to connect several heating zones together. The electrical specialist must install a safe system in the scope of the overall system.

Is it possible to control a boiler?

The EAZY Base 3 Balance base station has an output for the heat source requirement.
