REMKO Multi-talent - Manual (Page 5)

Function
It is the function of the Multi-
talent heat pump manager to
operate and effectively manage
the entire warm water pump
system including any additionally
installed heating appliances. The
multitude of functions provided
by the heat pump manager must
be configured in accordance with
the existing heating system. This
manual provides both installation
instructions and a overview of
what actually lies behind the heat
pump manager's configuration pa-
rameters. The following functions
are displayed in the heat pump
manager:
• Heat pump operation
• Weather managed regulation
of a direct heating circuit and
a mixing circuit (e.g.: floor
heating)
• Hot-water heating
• Cooling
• Solar function
• Demand oriented circulation
pump switching
• Automatic summer/
winter time change
• Individually configurable
reduction times and holiday
operation for heating circuits
and hot-water
• Cascade modulating heating
appliance
• Cascade switching heating ap-
pliance
• Bivalence regulator
Control
principles
Using an outdoor temperature
sensor and the selected heating
curve, the heat pump manager
continuously establishes the target
flow temperature and compares
this temperature with the cur-
rent system flow temperature
(F8-T-Collector). The heat pump
manager calculates the modula-
tion depth in % as a function of
the difference between the current
flow temperature and the target
temperature. The modulation
depth reflects the system's target
output in %, for example the heat
output made necessary by the cur-
rent outdoor temperature.
