LCD REMOTE CONTROLLER
8.4.3 Individual Heating/Cooling household in combination with Individual DHW production (II)
This installation is suitable in case that not such a high amount of
DHW is demanded, or more than one Sub unit is needed to heat
one single tank.
DHW production or Space Heating/Cooling production
is simultaneously. This means that YUTAKI CASCADE
CONTROLLER can operate for Space Heating/Cooling
application and each configured Sub can operate for DHW when
needed. Each Circuit 2 will continue working by using Mixing kit
and accumulated water into C1 Buffer tank
•
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.

5 Additional configuration:
a. Each unit need to assign Refrigerant address
(0/1/2/3/4/5/6/7) in accordance with YUTAKI 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
CASCADE CONTROLLER or if the Sub unit has its own
tank and is in demand ON conditions).
