Description
The lower menu is only displayed when a buffer cy-
C4
linder is used (e.g. Hydraulic Plans 2 and 4, and pos-
sibly on more than one occasion when a VR 60 is
41°C
used).
30°C
In the direct heating mode (e.g. Hydraulic Plans 1 and
Off
3), the upper display is shown.
-183°min
Setpoint flow temp.: Setpoint flow temperature for
the heating circuit
Flow temp. VF2: Current flow temperature VF2.
C4
Energy integral: The energy integral is the cumula-
tive difference between the VF2 flow temperature
41°C
and the target flow temperature per minute. The
29°C
heat pump starts when the energy deficit is at a de-
Off fined level (see Energy balance control, Chap. 8.4.2)
Status of pump: indicates whether the pump is tur-
Open
ned on or off (ON/OFF).
Status hydr. mixer: Caution! The OPEN/CLOSED in-
dication describes the direction in which the control
system is driving the mixer. If the mixer is not ac-
tivated, OFF appears.
If a VR 60 is connected, the lower menu appears se-
veral times (for each heating circuit).
Only when using the VR 90 / VR 80 remote control:
C5
Switch-on room temperature:
None = Room temperature from the remote control
is not taken into account.
Switch on = In addition to the selected heating
curve, the heating flow temperature is also affected
23°C
by the difference between the setpoint and current
room temperatures.
Thermostat = The room temperature from the VR
90 is used directly for controlling - i.e., the function
of a room thermostat.
Remote control: Automatically indicates whether a
VR 90 remote control unit is connected (YES/NO). If
YES, the room temperature measured by the VR 90
is also displayed.
This menu occasionally appears on more than one
occasion (for each heating circuit).
You can select the starting day for floor drying; the
C6
flow temperature setpoint is automatically called up
in accordance with the floor drying function (daily
Temp.
values 25/30/35 °C), see Chap. 8.3 "Settable auxilia-
0°C
ry functions".
It takes approx. 20 seconds for the actual value to
be displayed!
Deactivating the floor drying function: set to Day
"0".
Depending on the configuration of the heating sys-
tem, the display will indicate for other heating cir-
cuits if required.
