Advantages
Matches with most application
requirements for ground-sourced heat
pumps and fits with many industrial
processes requirements
Optimised operation of two units connected
in parrallele operation with operating time
equalisation
Quick and easy installation

Minimizes thermal dispersions condenser
side (key option for heat pump or heat
recovery applications) and allows
compliancy with special installation criteria
(hot parts insulated)
Allow isolation of various refrigerant circuit
components for simplified service and
maintenance
Easy to install, depending on site.
Reduced pressure drops
Easy to install, depending on site.
Reduced pressure drops
Covers applications with a high water
column evaporator side (typically high
buildings)
Covers applications with a high water
column condenser side (typically high
buildings)
Easy installation on sites with specific

Connects the unit by communication bus to
a building management system
Easy and high-speed connection by
ethernet line to a building management
system. Allows access to multiple unit
parameters

Increased condenser leaving water
temperature up to 70°C. Allows
applications with high condensing
temperature (heat pumps, installations with
not generously sized dry-coolers or more
generally, installations with dry-coolers in
hot climate). NOTE: to ensure control of
the condenser leaving water temperature,
this option must be fitted with 30XWH
units.
Reduced maximum power input and
current absorption: power cables and
protection elements can therefore be
downsized
Simple installation: for applications with
cold water at condenser inlet (ex. ground-
source, groundwater-source, superficial
water-source applications) the signal
permits to control a 2 or 3-way valve to
maintain condenser water temperature
(and so condensing pressure) at
acceptable values
