This manual is designed to be a quick guide to the most common type of instal-
lation for a Panasonic Monobloc system.
This assumes heating via a buffer tank or low loss header, domestic hot water
via a cylinder with sensor pocket and immersion heater, 3 port diverting valve
and remote room programmable temperature controller.
In the above system the monobloc units functions are controlled by the units own controller and this
is only used by the technician not the end user.
The end user controls the heating demand using a wireless room controller and can use this to set the
room temperature. If this includes a time clock then they can have different settings for different
times of the day or week with night and holiday set back.
The heat pump controls the domestic hot water temperature itself including for an optional sterilisa-
tion cycle using the 3 way valve and (if needed) the ‘Booster Heater’ which is the name Panasonic use
for the immersion heater.
There is an electric heater inside the monobloc unit. Panasonic refer to this as the
‘Backup
Heater’.
The 3 way valve is a diverting, not a mixing valve. When unpowered it provides flow to the buffer
tank. When powered it cuts off flow to the buffer tank and diverts it to hot water.
A buffer tank is necessary in order to provide a minimum water volume and also thermal separation
for the system. It will protect the unit from short cycling, heat exchanger damage and low water flow
trips. Ideally a buffer tank should have an auto air vent on top.
Important
—All piping
should be 28mm copper
as a minimum, larger if
plastic.
* Please note
—the monobloc unit contains a strainer
so an external one is optional as is a flowsetter.
* A magnetic filter is mandatory for all installations.
