Heating System Manager (Hsm) - Carrier AquaSnap 61AF 022 Installation, Operation And Maintenance Instructions

14 - HEATING SYSTEM MANAGER (HSM)

The Heating System Manager (HSM) accessory allows improved
integration of the 61AF heat pump to maximise energy efficiency
performance.
With three system levels for nine typical configurations, most
heating only applications are covered - from the simplest to the
most complex, such as interfacing with a district heating system.
Each of these accessory configurations is described in detail in
the IOM for these accessories.They offer:
- Choice of control options (on/off volt-free contact or 0-10 V
signal for increased performance),
- Domestic hot water production temperature control and
distribution.
The control box can supply all auxiliary devices such as the
circulating pumps or the mixing or switching valves.
The heat pump is controlled by a CCN bus and the control box
includes an NRCP2-BASE board, a SmartVu
as all required sensors.
Installation safety notes
• The hydraulic installation must be carried out by qualified personnel in accordance
with applicable laws and following standard accepted practices.
• The hydraulic installation must be regularly serviced.An incorrect hydraulic
installation that does not comply withthe safety, electrical and thermal standards,
as well as lacking/poor maintenance can lead to excessive pressures and cause
piping breaks.

Allows control of a non-reversible heating system that includes a 61AF heat pump
and a single heat emitter type or a single comfort zone. For optimised energy
efficiency the heat pump is controlled by a configurable weather compensation
system. The control box controls a supplementary electric heater or a stand-by
boiler. The control box supplies power to the circulating pumps.
