RS485
149B Bi-directional high-speed communication using
Modbus protocol over Ethernet network (IP)
Easy and high-speed connection by
ethernet line to a building management
system. Allows access to multiple unit
parameters
301-1101
High condensing temperature 150 Optimized compressor for operation at high
condensing temperature
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.
301-1101
Condensing temperature
limitation
150B Limitation of the maximum condenser leaving
water temperature to 45°C
Reduced maximum power input and
current absorption: power cables and
protection elements can therefore be
downsized
301-1101
Control for low cond.
temperature systems
152 Output signal (0-10 V) to control the condenser
water inlet valve
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
