[C‑07]=0: leaving water temperature control
Under leaving water temperature control, room frost protection is
NOT guaranteed. However, if [2‑06] is set to "1", limited frost
protection by the unit is possible:
▪ When the leaving water temperature home page is OFF and the
outdoor ambient temperature drops below 4°C, then the unit will
supply leaving water to the heat emitters to heat up the room
again, and the leaving water temperature setpoint will be lowered.

...then the following applies:
▪ When the leaving water
temperature home page is
OFF and the outdoor ambient
temperature drops below 4°C,
then the unit will supply
leaving water to the heat
emitters to heat up the room
again, and the leaving water
temperature setpoint will be
lowered.
▪ When the leaving water
temperature home page is ON,
the external room thermostat
is "Thermo OFF" and the
outdoor ambient temperature
drops below 4°C, then the unit
will supply leaving water to the
heat emitters to heat up the
room again and the leaving
water temperature setpoint will
be lowered.
▪ When the leaving water
temperature home page is ON
and the external room
thermostat is "Thermo ON",
then room frost protection is
guaranteed by the normal
logic.
▪ When the leaving water
temperature home page is
OFF, and the outdoor ambient
temperature drops below 4°C,
then the unit will supply
leaving water to the heat
emitters to heat up the room
again, and the leaving water
temperature setpoint will be
lowered.
▪ When the leaving water
temperature home page is ON,
the operation mode
"heating", and the outdoor
ambient temperature drops
below 4°C, then the unit will
supply leaving water to the
heat emitters to heat up the
room again, and the leaving
water temperature setpoint will
be lowered.
▪ The selection of "cooling" or
"heating" is done via the user
interface. When the leaving
water temperature home page
is ON and the operation mode
is "cooling", then there is no
protection.
▪ When the leaving water temperature home page is ON and the
operation mode is "heating", then the unit will supply leaving water
to the heat emitters to heat up the room according to normal logic.
▪ When the leaving water temperature home page is ON and the
operation mode is "cooling", then there is no protection.
Shut-off valve
The shut-off valve is in the main leaving water temperature zone,
and is connected to the heating/cooling output.
NOTICE
The output of the shut‑off valve is NOT configurable. Do
NOT change the value of setting [F‑0B]. Only connect NO
(normal open) shut‑off valves.
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
rises above this value, space heating is turned OFF to avoid
overheating.

Automatic heating/cooling changeover
ONLY applicable
EBLQ011+014+016CAW1. 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
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
"8 Configuration" on page 42).
When the outdoor temperature is between the space cooling On and
the space heating OFF temperature, the operation mode remains
unchanged unless the system is configured in room thermostat
control with one leaving water temperature zone and quick heat
emitters. In that case, the operation mode will change based on:
▪ Measured indoor temperature: besides the heating and the
cooling desired room temperature, the installer sets a hysteresis
value (e.g. when in heating, this value is related to the desired
cooling temperature) and an offset value (e.g. when in heating,
this value is related to the desired heating temperature). Example:
the desired room temperature in heating is 22°C and in cooling
24°C, with a hysteresis value of 1°C and an offset of 4°C.
Changeover from heating to cooling will occur when the room
