Power factor correction capacitors (optional)
0-10 V clamps for condensing control (optional)
Control
A new optimized control is supplied on all the units with a
simple user interface (possibility to customize keys func-
tions and to set menus visibility).
In addition to standard features as water temperature
control (with possibility to choose LWT/EWT probe), the
control can also manage following functions:
Dynamic set point (4-20 mA, 0-1V, 0-5V, 0-10V)
Double set point
OAT compensation
Boiler integration
Condensing control
Auto adaptative function to reduce the water content of
the plant
Advanced pump management (both primary circuit and
source side)
Remote keyboard (accessory) with possibility to con-
nect (up to 100 m distance) without any serial interface
Safety
Each unit is equipped with following electrical/refrigerant
/hydraulic safety devices:
Door lock main isolating switch
Phase monitor control
High pressure switch with manual reset
Discharge safety valve
Low pressure switch with automatic / manual reset
Anti-freeze probe (leaving water temperature)
Differential pressure switch (source / plant side)
