Unit for air to water heat pump system
4PW67904-1 – 01.2011
10.2. Room thermostat installation configuration
The following table summarizes the required configuration and
thermostat wiring at the terminal block (X2M: 1, 2, 3, 4) in the switch
box. Pump operation is listed in the third column. The three last
columns indicate whether the following functionality is available on
the user interface (UI) or handled by the thermostat (T):
•
space heating or cooling on/off (
y
)
•
heating/cooling changeover (
=
)
•
heating and cooling schedule timers (
pr
)
10.3. Pump operation configuration
Without room thermostat: DIP switch SS2-3=OFF
When no thermostat is connected to the unit, pump operation will be
determined by the leaving water temperature.
To force continuous pump operation when no room thermostat is
connected do the following:
-
set toggle switch SS2-3 to ON,
-
short-circuit the terminal numbers 1-2-4 on the terminal block
in the switch box.
With room thermostat DIP switch: SS2-3=ON
When the thermostat is connected to the unit, the pump will operate
continuously whenever there is heating or cooling demand requested
by the thermostat.
Dual set point
When dual set point is enabled, the pump operation will be
determined depending on the status of the DIP switch SS2-3 and set
point selection contacts. Refer to the table below.
The following table summarizes the required configuration and wiring
at the terminal block (X2M: 1, 2, 4) in the switch box. Pump operation
is listed in the third column. The three last columns indicate whether
the following functionality is available on the user interface (
UI
) or
handled by the set point selection contacts SP1 and SP2:
•
space heating or cooling on/off (
y
)
•
heating/cooling changeover (
=
)
•
heating and cooling schedule timers (
pr
)
■
When no room thermostat is connected to
the unit, toggle switch SS2-3 should be set to
OFF.
■
When the room thermostat is connected to
the unit, toggle switch SS2-3 should be set to
ON.
■
On the room thermostat, confirm the correct settings (
6®02
=yes,
6®05
=9,
6®06
=5) to prevent the pump from repeatedly turning on
and off (i.e. chattering), and thereby impacting the lifetime of
the pump.
INFORMATION
■
When a room thermostat is connected to the unit, the
heating and cooling schedule timers are never
available. Other schedule timers are not affected. For
more information on the schedule timers, refer to the
operation manual.
■
When a room thermostat is connected to the unit, and
the
=
button or
y
button is pressed, the
centralised control indicator
e
will flash to indicate
that the room thermostat has priority and controls
on/off operation and changeover operation.

INFORMATION
To set the pump speed, refer to
"10.8. Setting the pump
speed" on page 31
.
INFORMATION
When dual set point is enabled, the "forced continuous
pump operation" is not possible. When SS2-3 is ON while
SP1 and SP2 are both closed, the pump operation will be
the same operation as "with room thermostat" and the
second set point will be the applicable set point. Refer to
the table below.
