AIR-TO-WATER HEAT PUMP WITH INTEGRATED
HYDRONIC MODULE 30RQM/30RQP 160-520
Superior reliability
■■ State-of-the-art concept
-- Two independent refrigerant circuits; the second
one automatically takes over, if the first one
develops a fault, maintaining partial cooling under all
circumstances
-- All compressor components are easily accessible on
site minimising down-time
-- V-coil design to protect the coils against hail impact
-- Optional anti-corrosion coil coating for use in
moderately corrosive environments.
-- Electronic flow switch. Auto-setting according to
cooler size and fluid type
■■ Auto-adaptive control
-- Control algorithm prevents excessive compressor
cycling and permits reduction of the water quantity in
the water loop (Carrier patent)
-- A
utomatic compressor unloading in case of
abnormally high condensing pressure
-- Automatic fan speed adjustment in case of coil fouling
(30RQP models)
-- Smooth fan start to increase unit lifetime (30RQP
models).
-- ENERGY MANAGEMENT MODULE (p4 du PSD)
-- HYDRONIC MODULE (p6 du PSD)
-- VARIABLE WATER FLOW SYSTEM (p7 du PSD)
■■ Exceptional endurance tests
-- Partnerships with specialised laboratories and use of
limit simulation tools (finite element calculation) for the
design of critical components
-- Transport simulation test on an endurance circuit
based on a military standard.

-- I ntuitive and user-friendly 5 inch touch screen interface
-- Concise and clear information is available in local
languages
-- Complete menu, customised for different users (end
user, service personnel or Carrier engineers).
Remote management (standard)
Units with Touch Pilot control can be easily accessed from
the internet, using a PC with an Ethernet connection. This
makes remote control quick and easy and offers significant
advantages for service operations.
The AquaSnap is equipped with an RS485 serial port that
offers multiple remote control, monitoring and diagnostic
possibilities. Carrier offers a vast choice of control products,
specially designed to control, manage and supervise the
operation of an air conditioning system. Please consult your
Carrier representative for more information.
The AquaSnap also communicates with other building
management systems via optional communication gateways.
A connection terminal allows remote control of the AquaSnap
by wired cable:
-- Start/stop: Opening of this contact will shut down the
unit
-- Dual set-point: Closing of this contact activates a
second set-point (example: unoccupied mode).
-- Demand limit: Closing of this contact limits the
maximum heat pump capacity to a predefined value.
-- Operation indication: This volt-free contact indicates
that the heat pump is operating (cooling load).
-- Alarm indication: This volt-free contact indicates the
presence of a major fault that has led to the shut-down
of one or several refrigerant circuits.

AIR TREATMENT
The Touch Pilot features a control with advanced
communication technology over Ethernet (IP), user-friendly
and intuitive user interface with 5” colour touch screen.
■■ Energy management
-- Internal time schedule clock: Controls heat pump on/
off times and operation at a second set-point
-- Set-point offset based on the outside air temperature
-- Master/slave control of two heat pumps operating in
parallel with operating time equalisation and automatic
change-over in case of a unit fault.
■■ Integrated advanced communication features
-- Night mode: Capacity and fan speed limitation for
reduced noise level
-- With hydronic module: Water pressure display and
water flow rate calculation
-- Easy and high-speed communication technology over
Ethernet (IP) to a building management system
-- Access to multiple unit parameters.
