4.4 Configuration examples

The following examples and illustrations are for illustrative purpose and do not cover all the
possible installations.
4.4.1 Individual Heating/Cooling household in combination with common

DHW production

This installation is suitable in case a high amount of DHW at a specific setting temperature is
required.
When YUTAKI CASCADE CONTROLLER is generating water for DHW tank, production of hot or
chilled water for Space Heating/Cooling application is stopped until DHW production stops.
In this scenario, YUTAKI CASCADE CONTROLLER manage DHW tank and Water temperature produc-
tion for Space Heating or Cooling:
• C1 buffer tank depicted in the picture is C1 circuit for YUTAKI CASCADE CONTROLLER.
• C1 buffer tank is managed by means YUTAKI CASCADE CONTROLLER unit without thermostat.
• Each C2 circuit of each YUTAKI Sub unit is assigned to a specific household.
• Each C2 mixing kit of each YUTAKI Sub unit guarantees C2 water temperature at each
household.
• Each C2 circuit can have a wired or wireless thermostat which is connected to each Sub unit
• Each C2 circuit can have an Outdoor OTC Temperature by Outdoor unit or Wired Sensor
accessory.
