Leaving water temperature maximum modulation
ONLY applicable in room thermostat control and when modulation is
enabled. The maximum modulation (=variance) on the desired
leaving water temperature decided on the difference between the
actual and desired room temperature, e.g. 3°C modulation means
the desired leaving water temperature can be increased or lowered
by 3°C. Increasing the modulation results in better performance (less
On/OFF, faster heat up), but note that depending on the heat
emitter, there MUST ALWAYS be a balance (refer to the design and
selection of the heat emitters) between the desired leaving water
temperature and the desired room temperature.
# Code Description
N/A [8-06] 0°C~10°C (default: 3°C)
Weather dependent cooling allowance
ONLY applicable for RHBX and RHVX. It is possible to disable
weather dependent cooling, meaning the desired leaving water
temperature in cooling operation does NOT depend on the outdoor
ambient temperature and this regardless whether weather
dependent is selected or NOT. Both for the main leaving water
temperature zone as for the additional leaving water temperature
zone, this can be set separately.
# Code Description
N/A [1-04] Weather dependent cooling of the main
leaving water temperature zone is…
0 (disabled)
1 (enabled) (default)
N/A [1-05] Weather dependent cooling of the
additional leaving water temperature
zone is…
0 (disabled)
1 (enabled) (default)
Temperature ranges (room temperature)
ONLY applicable in room thermostat control. In order to save energy
by preventing overheating or undercooling the room, you can limit
the range of the room temperature, both for heating and/or cooling.
NOTICE
When adjusting the room temperature ranges, all desired
room temperatures are also adjusted to guarantee they are
between the limits.
# Code Description
Room temp. range
[A.3.2.1.2] [3-06] Maximum temp (heating)
18°C~30°C (default: 30°C)
[A.3.2.1.1] [3-07] Minimum temp (heating)
12°C~18°C (default: 12°C)
[A.3.2.1.4] [3-08] Maximum temp (cooling)
25°C~35°C (default: 35°C)
[A.3.2.1.3] [3-09] Minimum temp (cooling)
15°C~25°C (default: 15°C)
Room temperature step
ONLY applicable in room thermostat control and when the
temperature is displayed in °C.
# Code Description
[A.3.2.4] N/A Room temp. step
1°C (default). The desired room
temperature on the user interface is
settable per 1°C.
0.5°C. The desired room temperature
on the user interface is settable per
0.5°C. The actual room temperature is
displayed with an accuracy of 0.1°C.
Room temperature hysteresis
ONLY applicable in case of room thermostat control. The hysteresis
band around the desired room temperature is settable. It is
recommended NOT to change the room temperature hysteresis as it
is set for an optimal use of the system.

# Code Description
N/A [9-0C] 1°C~6°C (default: 1°C)
Room temperature offset
ONLY applicable in case of room thermostat control. You can
calibrate the room temperature sensor. It is possible to give an offset
to the room thermistor value measured by the user interface. The
settings can be used to compensate for situations where the user
interface CANNOT be installed on the ideal installation location (see
installation manual and/or installer reference guide).
# Code Description
Room temp. offset: Offset on the actual room temperature
measured on the user interface sensor.
[A.3.2.2] [2-0A] –5°C~5°C, step 0.5°C (default: 0°C)
Room frost protection
Room frost protection prevents the room from getting too cold. This
setting behaves differently depending on the set unit control method
([C‑07]). Perform actions according to the table below:
Unit control method ([C‑07]) Room frost protection
Room thermostat control
([C‑07]=2)
Allow for the room thermostat to
take care of room frost
protection:
Set [2‑06] to "1"
Set the room antifrost
temperature ([2‑05]).
External room thermostat control
([C‑07]=1)
Allow for the external room
thermostat to take care of room
frost protection:
Turn ON the leaving water
temperature home page.
Set auto emergency ([A.5.1.2])
to "1".
Leaving water temperature
control ([C‑07]=0)
Room frost protection is NOT
guaranteed.
NOTICE
If the system does NOT contain a backup heater, do NOT
change the default room antifrost temperature.
