Hydronic module
-- The electronic expansion device (EXV) allows operation
at a lower condensing pressure (EER, COP and
ESEER optimisation).
-- Dynamic superheat management for better utilisation
of the water heat exchanger surface.
-- Defrost cycle optimisation (30RQSY)
■■ Reduced maintenance costs
-- Maintenance-free scroll compressors
-- Fast diagnosis of possible incidents and their history
via the Touch Pilot Junior control
-- R410A refrigerant is easier to use than other
refrigerant blends
HEATING
Environmentally balanced
-- Single or dual water pump (as required) with operating
time balancing and automatic changeover to the backup pump if a fault develops
-- Water filter protects the water pump against
circulating debris
-- Pressure measurement, using two pressure
transducers and allowing indication of water flow rate,
water pressure and lack of water.
-- High-capacity membrane expansion tank ensures
pressurisation of the water circuit
-- Overpressure valve, set to 4 bar
-- Speed variator on the pumps (option) to ensure the
correct flow rate, based on the system requirements
-- Thermal insulation and frost protection down to -20°C,
using an electric resistance heater (see table of
options)
■■ Simplified electrical connections
-- A single power supply point without neutral
-- Main disconnect switch (option 70) with high trip
capacity
-- Transformer for safe 24 V control circuit supply
included
■■ Fast commissioning
-- Systematic factory operation test before shipment
-- Quick-test function for step-by-step verification of the
instruments, electrical components and motors
Economical operation
■■ Variable-speed pump (option)
-- The control algorithm adjusts
