Item Operation flow and applicable data, etc. Operation description
7-1.
Basic
Operation
1) Operation control
Remote controller
1. Purpose
The operations of the
hydro unit and the
outdoor unit are
controlled according to
user-defined operation
condition settings.
2. Details
The operation controls
include those shown on
the left.
3. Operations
1) An operation condition
is selected with the
remote controller.
2) Setting the remote
controller button to
“ON” transmits a signal
to the hydro unit.
3) The hydro unit
controller controls the
operations shown on
the left while also
controlling the water 2-
way valve, water 3-way
valve, circulation
pump, mixing valve,
hot water cylinder
heater, and backup
heater.
4) The hydro unit
controller transmits an
operation instruction to
the outdoor unit, and
uses serial signals to
transmit and receive
control statuses.
5) The outdoor unit
control unit performs
the operation controls
shown on the left while
also controlling the
compressor, outdoor
fan motor, pulse motor
valve, 4-way valve, 2-
way valve, and bottom
plate heater.
