In case of… …then the following applies:
Two leaving water temperature
zones ▪ 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 is
"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.
[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.
▪ 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.
Shut-off valve
The following is only applicable in case of 2 leaving water
temperature zones. In case of 1 leaving water temperature zone,
connect the shut-off valve to the heating output.
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 demand from 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 12 .
# Code Description
[A.3.1.1.6.1] [F-0B] The shut-off valve:
▪ 0 (No)(default): is NOT influenced by
heating demand.
▪ 1 (Yes): closes when there is NO
heating 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).
Operation range
Depending on the average outdoor temperature, the operation of the
unit in space heating is prohibited.
Space heating OFF temp: When the averaged outdoor temperature
raises above this value, space heating is turned OFF to avoid
overheating.
# Code Description
[A.3.3.1] [4-02] ▪ 08: 14°C~35°C (default:
25°C)
▪ 16: 14°C~35°C (default:
35°C)
8.3.2 Domestic hot water control: advanced
Preset tank temperatures
Only applicable when domestic hot water preparation is scheduled
or sch reheat.
You can define preset tank temperatures:
▪ storage economic
▪ storage comfort
▪ reheat
▪ reheat hysteresis
Preset values make it easy to use the same value in the schedule. If
you later want to change the value, you only have to do it in 1 place
(see also operation manual and/or user reference guide).
Storage comfort
When programming the schedule, you can make use of the tank
temperatures set as preset values. The tank will then heat up until
these setpoint temperatures have been reached. Additionally, a
storage stop can be programmed. This feature puts a stop to tank
heating even if the setpoint has NOT been reached. Only program a
storage stop when tank heating is absolutely undesirable.
# Code Description
[7.4.3.1] [6-0A] 30°C~[6‑0E]°C (default: 60°C)
Storage eco
The storage economic temperature denotes the lower desired tank
temperature. It is the desired temperature when a storage economic
action is scheduled (preferably during day).
# Code Description
[7.4.3.2] [6-0B] 30°C~min(50, [6‑0E])°C (default: 45°C)
Reheat
The desired reheat tank temperature is used:
▪ in reheat mode of scheduled + reheat mode: The guaranteed
minimum tank temperature is set by T
HP OFF
–[6‑08], which is either
[6‑0C] or the weather dependent setpoint, minus the reheat
hysteresis. If the tank temperature drops below this value, the tank
is heated up.
▪ during storage comfort, to prioritize the domestic hot water
preparation. When the tank temperature raises above this value,
domestic hot water preparation and space heating are executed
sequentially.
# Code Description
[7.4.3.3] [6-0C] 30°C~min(50, [6‑0E])°C (default: 48°C)
Reheat hysteresis
Only applicable when domestic hot water preparation is sch
reheat.
