13 - OPERATION OF 61WG UNITS WITH THE HEATING
SYSTEM MANAGER (HSM)
HSM accessory: 00PPG000488000- or 00PPG000488100- or
00PPG000488200-
The Heating System Manager (HSM) accessory allows
improved integration of the 61WG heat pump to maximise
energy efciency performance.
With three system levels for nine typical congurations, 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 congurations is described in detail
in the user manual for these accessories. They offer:
• choice of additional 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 Pro-Dialog interface
as well as all required sensors.
