LCD REMOTE CONTROLLER

8.4 CONFIGURATION EXAMPLES

The following examples and illustrations are for illustrative purpose and do not cover all the possible installations.
8.4.1 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 production 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

5 Additional configuration:
a. Each unit need to assign Refrigerant address
(0/1/2/3/4/5/6/7) in accordance with CASCADE
CONTROLLER Modules Configuration
b. The water pump in each Sub unit can be set to Standard
(continuous operation) or Economic mode (operation only
in case that there is operation demand from the CAS-
CADE CONTROLLER or if the Sub unit has its own tank
and is in demand ON conditions).
