Weather dependent cooling allowance
Only applicable for EHBX and EHVX. It is possible to disable
weather dependent cooling, meaning the desired leaving water
temperature in cooling operation doesn't depend on the outdoor
ambient
temperature
and
this
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.

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.

temperature on the user interface is
settable per 1°C.
▪ 0.5°C The desired room temperature

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. Daikin
advises NOT to change the room temperature hysteresis as it is set
for an optimal use of the system.

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 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 7.
