This VRV IV heat recovery system is equipped with advanced energy saving
functionality. Depending on the priority, emphasises can be put on energy saving
or comfort level. Several parameters can be selected, resulting in the optimal
balance between energy consumption and comfort for the particular application.
Several patterns are available and explained below. Modify the parameters to the
needs of your building and to realize the best balance between energy
consumption and comfort.
No matter which control is selected, variations on the behaviour of the system are
still possible due to protection controls to keep the unit operating under reliable
conditions. The intentional target, however, is fixed and will be used to obtain the
best balance between energy consumption and comfort, depending on the
application type.
Care should be taken about selection procedures and system setups, especially
when using Hydrobox units. The requested leaving water temperature from the
Hydrobox has priority over this energy saving control, as it is related to the
required water temperature.
Basic
The refrigerant temperature is fixed independent from the situation. It
corresponds to the standard operation which is known and can be expected from/
under previous VRV systems.
