Preset tank temperatures
Only applicable when domestic hot water preparation is scheduled or scheduled +
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
[7.4.3.1] [6-0A]
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
[7.4.3.2] [6-0B]
Reheat
The desired reheat tank temperature is used:
▪ in reheat mode of scheduled + reheat mode: The guaranteed minimum tank
temperature is set by T
dependent setpoint, minus the reheat hysteresis. If the tank temperature drops
below this value, the tank is heated up.
# Code
[7.4.3.3] [6-0C]
Reheat hysteresis
Only applicable when domestic hot water preparation is scheduled + reheat.
# Code
N/A [6-08]
Weather dependent
The weather dependent installer settings define the parameters for the weather
dependent operation of the unit. When weather dependent operation is active the
desired tank temperature is determined automatically depending on the averaged
30°C~[6‑0E]°C
30°C~min(50, [6‑0E])°C
–[6‑08], which is either [6‑0C] or the weather-
