Room temperature offset
Only applicable in case of room thermostat control. You can
calibrate the (external) room temperature sensor. It is possible to
give an offset to the room thermistor value measured by the user
interface or by the external room sensor. The settings can be used
to compensate for situations where the user interface or external
room sensor cannot be installed on the ideal installation location
(see installation manual and/or installer reference guide).

Room temp. offset: Offset on the actual room temperature
measured on the user interface sensor.

−5~5°C, step 0.5°C (default: 0°C)
Ext. room sensor offset: Only applicable if the external room sensor
option is installed and configured (see [C-08])

−5~5°C, step 0.5°C (default: 0°C)
Room frost protection
Only applicable in case of room thermostat control. When the actual
room temperature would drop below the room frost temperature, the
unit will supply leaving water (in heating operation mode) to the heat
emitters to heat up the room again.
NOTICE
Even if the room thermostat control is OFF on the user
interface, room frost protection remains active.

Shut-off valve
Only applicable in case of 2 leaving water temperature zones.
The shut-off valve, which is in the main leaving water temperature
zone, output is configurable.
INFORMATION
During defrost operation, the shut-off valve is always
opened.
Thermo On/OFF: the valve closes, depending on [F-0B] when there
is no heating and/or demand of the room in the main zone. Enable
this setting to:
▪ avoid leaving water supply to the heat emitters in the main LWT
zone (through the mixing valve station) when there is request from
the additional LWT zone.
▪ activate the On/OFF pump of the mixing valve station only when
there is demand. See "5 Application guidelines" on page 8.

Code
[A.3.1.1.6.1] [F-0B]
The shut-off valve:
0 (No)(default): is NOT influenced by
heating or cooling demand.
1 (Yes): closes when there is NO heating
or cooling demand.
INFORMATION
The setting [F‑0B] is only valid when there is a thermostat
or external room thermostat request setting (NOT in case
of leaving water temperature setting).
Cooling: Only applicable for EHBX and EHVX. The shut-off valve
closes, depending on [F-0C] when the unit is running in cooling
operation mode. Enable this setting to avoid cold leaving water
through the heat emitter and the forming of condensation (e.g. under
floor heating loops or radiators).
#
Code
[A.3.1.1.6.2] [F-0C]
The shut-off valve:
0 (No): is NOT influenced by changing
the space operation mode to cooling.
1 (Yes)(default): closes when the space
operation mode is cooling.
Operation range
Depending on the average outdoor temperature, the operation of the
unit in space heating or space cooling is prohibited.
Space heating OFF temp: When the averaged outdoor temperature
raises above this value, space heating is turned OFF to avoid
overheating.

14~25°C (default: 25°C)
▪ EHBH/X16 and EHVH/X16: 14~35°C
(default: 35°C)
The same setting is also used in
automatic heating/cooling changeover.
Space cooling On temp: Only applicable for EHBX and EHVX. When
the averaged outdoor temperature drops below this value, space
ooling is turned OFF.
#
Code
[A.3.3.2]
[F-01]
10~35°C (default: 20°C)
The same setting is also used in
automatic heating/cooling changeover.
Automatic heating/cooling changeover
Only applicable for EHBX and EHVX. The end-user sets the
desired operation mode on the user interface: Heating, Cooling or
Automatic (see also operation manual/user reference guide). When
Automatic is selected, the changing of the operation mode is based
on:
▪ Monthly allowance for heating and/or cooling: the end-user
indicates on a monthly base which operation is allowed (# [7:5]):
both heating/cooling or heating only or cooling only. If the allowed
operation mode changes to cooling only, the operation mode
changes to cooling. If the allowed operation mode changes to
heating only, the operation mode changes to heating.
▪ Averaged outdoor temperature: the operation mode will be
changed in order to always be within range determined by the
space heating OFF temperature for heating and the space cooling
On temperature for cooling. If the outdoor temperature drops, the
operation mode switches to heating and vice versa. Note that the
outdoor temperature will be time-averaged (see "8 Configuration"
on page 41).
