▪
For each room with heat pump convectors: The desired room temperature is set
via the controller of the heat pump convectors. There are different controllers
and setups possible for the heat pump convectors. For more information, see:
-
The installation manual of the heat pump convectors
-
The installation manual of the heat pump convector options
-
The addendum book for optional equipment
▪
For each room with underfloor heating: The desired room temperature is set via
the external room thermostat (wired or wireless).
▪
The user interface connected to the indoor unit decides the space operation
mode. Mind that the operation mode on each external room thermostat and
remote controller of the heat pump convectors must be set to match the indoor
unit.
INFORMATION
To increase comfort and performance, we recommend to install the valve kit option
EKVKHPC on each heat pump convector.

Unit temperature control:
▪
#: [A.2.1.7]
▪
Code: [C-07]
0 (
LWT control
): Unit operation is
decided based on the leaving water
temperature.
6.2.3 Multiple rooms – Two LWT zones
In this document:
▪
Main zone = Zone with the lowest design temperature in heating, and the highest
design temperature in cooling
▪
Additional zone = Zone with the highest design temperature in heating, and the
lowest design temperature in cooling
CAUTION
If there is more than one leaving water zone, ALWAYS install a mixing valve station in
the main zone to decrease (in heating)/increase (in cooling) the leaving water
temperature when the additional zone has demand.
Typical example:
Room (zone)
Heat emitters: Design temperature
Living room (main zone)
Underfloor heating:
▪
In heating: 35°C
▪
In cooling
(a)
: 20°C (only refreshment,
no real cooling allowed)
Bed rooms (additional zone)
Heat pump convectors:
▪
In heating: 45°C
▪
In cooling: 12°C
(a)
In cooling mode, you can allow the underfloor heating (main zone) to provide refreshment
(no real cooling), or NOT allow it. See setup below.
