This manual is designed to be a quick guide to the most common type of installation for a LG Therma V R32
Monobloc system.
This assumes heating via Buffer Tank, domestic hot water via a cylinder with sensor pocket and immersion
heater, 3 port valve controlled Via the LG controller and Heating Control Via Third Party.
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 third party wired controller and can use this to set the room
temperature at different times of the day.
The heat pump controls the domestic hot water temperature itself (including for an optional sterilization cycle)
and is assisted by the immersion heater. 2 port valves MUST not to be used upstream of the buffer.
The hot water control is managed through the LG controller. Hot water takes priority over heating.
There is no electric heater inside the monobloc unit, however there is a additional booster heater available.
There is a flow sensor located within the unit.
A pump is installed within the Monobloc, However a second pump will be required on downstream of the buffer to
feed the heating circuits
A strainer must be installed in the return pipework to the mono block. It is strongly recommended by LG in addition to
this a Magnetic filter and Flow setter should also be installed.
