Common heating / cooling household in combination with common DHW production


Type of application
In the schematic below, the production of DHW and space heating/cooling is not simultaneous. When the cascade installation is generating water for the DHW tank, production of hot or chilled water for space heating or cooling application is stopped until DHW production stops.

Additional information:
In this scenario, Yutaki cascade controller manage both DHW tank and space heating/cooling for the household.
Circuit 1 and circuit 2 management is performed by the Yutaki cascade controller and they have wired / wireless / no thermostats or any combination option.
Installer shall determine proper usage of collector systems.

Common heating / cooling household in combination with individual DHW production


Type of application
In the schematic below, the production of DHW and space heating/cooling is simultaneous. This installation is suitable when there are different demands of DHW applications (different DHW setting temperature, different DHW usage patterns, variety of DHW volume required).

Additional information:
In this scenario, Yutaki Cascade Controller can operate for space heating – cooling application and each configured Yutaki slave can operate for DHW when needed. Each circuit 2 will continue working by using mixing kit and accumulated water into C1 buffer tank.
In this scenario, Yutaki Cascade Controller manage both space heating/cooling household and Yutaki DHW production:
Circuit 1 and circuit 2 management is performed by means of Yutaki Cascade Controller
Circuit 1 and circuit 2 can have wired/wireless/none thermostats or any combination option
Installer shall determine proper usage of collector systems

Individual heating / cooling household in combination with common DHW production


Type of application
In the schematic below, the production of DHW and space heating/cooling is not simultaneous. When the cascade installation is generating water for the DHW tank, production of hot or chilled water for space heating or cooling application is stopped until DHW production stops. This installation is suitable in case a high amount of DHW at a specific setting temperature is required.

Additional information:
In this scenario, Yutaki cascade controller manage both DHW tank and water temperature production for space heating/cooling.
Circuit 1 buffer tank correspond to the first circuit for the Yutaki cascade controller. Management is performed by the Yutaki cascade controller without thermostat.
Each circuit 2 of each Yutaki slave unit is assigned to a specific household. Water temperature of each circuit 2 is guaranteed by the second temperature kit of each slave unit. Each circuit 2 can have a wired or wireless thermostat which is connected to each slave unit. Each circuit 2 can have an outdoor OTC temperature by outdoor unit or wired sensor accessory.

Additional information:
In this scenario, Yutaki Cascade Controller can operate for space heating – cooling application and each configured Yutaki slave can operate for DHW when needed. Each circuit 2 will continue working by using mixing kit and accumulated water into C1 buffer tank (first circuit for Yutaki Cascade Controller).
Circuit 1 buffer tank is managed by Yutaki Cascade Controller without thermostat.
Each circuit 2 of each Yutaki slave unit is assigned to a specific household.
Each circuit 2 mixing kit of each Yutaki slave unit guarantees circuit 2 water temperature household.
Each circuit 2 can have a wired or wireless thermostat which is connected to each slave unit.
Each circuit 2 can have an outdoor OTC temperature by outdoor unit or wired sensor accessory.
