Heat pump convectors
Setup
Q
The heat pump convectors are directly connected to the indoor
unit.
Q
The desired room temperature is set via the remote controller of
the heat pump convectors.
Q
The space heating/cooling demand signal is sent to one digital
input on the indoor unit (X2M/1 and X2M/4).
Q
The space operation mode is sent to the heat pump convectors
by one digital output on the indoor unit (X2M/33 and X2M/34).
Configuration
Benefits
Q
Cooling
.
The heat pump convector offers, besides heating
capacity, also excellent cooling capacity.
Q
Efficiency
.
Optimal energy efficiency because of the interlink
function.
Q
Stylish
.
Combination: Under floor h Heat pump
convectors
Q
Space heating is provided by:
Q
The under floor heating
Q
The heat pump convectors
Q
Space cooling is provided by the heat pump convectors only.
The under floor heating is shut off by the shut-off valve.
Setup
Q
The heat pump convectors are directly connected to the indoor
unit.
Q
A shut-off valve (field supply) is installed before the under floor
heating to prevent condensation on the floor during cooling
operation.
Q
The desired room temperature is set via the remote controller of
the heat pump convectors.
Q
The space heating/cooling demand signal is sent to one digital
input on the indoor unit (X2M/1 and X2M/4)
Q
The space operation mode is sent by one digital output (X2M/33
and X2M/34) on the indoor unit to:
Q
The heat pump convectors
Q
The shut-off valve
Configuration
Benefits
Q
Cooling
.
Heat pump convectors provide, besides heating
capacity, also excellent cooling capacity.
Q
Efficiency
. Under floor heating has the best performance with
Altherma LT.
Q
Comfort
.
The combination of the two heat emitter types
provides:
Q
The excellent heating comfort of the under floor heating
Q
The excellent cooling comfort of the heat pump convectors
5.2.2 Multiple rooms – One LWT zone
If only one leaving water temperature zone is needed because the
design leaving water temperature of all heat emitters is the same, you
do NOT need a mixing valve station (cost effective).
Example: If the heat pump system is used to heat up one floor where
all the rooms have the same heat emitters.

INFORMATION
When using multiple heat pump convectors, make sure
each one receives the infrared signal from the remote
controller of the heat pump convectors.
