4.
You can now select to take read outs for different
outdoor temperatures by turning the control knob
to the right or left and read off the corresponding
flow temperature.
5.
Press the OK or Back button to exit read off mode.
TIP
Wait 24 hours before making a new setting,
so that the room temperature has time to
stabilise.
If it is cold outdoors and the room temperature
is too low, increase the curve slope by one in-
crement.
If it is cold outdoors and the room temperature
is too high, lower the curve slope by one incre-
ment.
If it is warm outdoors and the room temperat-
ure is too low, increase the curve offset by one
increment.
If it is warm outdoors and the room temperat-
ure is too high, lower the curve offset by one
increment.
Menu 1.9.2 - external adjustment
climate system
Setting range: -10 to +10 or desired room temperat-
ure if the room sensor is installed.
Default value: 0
Connecting an external contact, for example, a room
thermostat or a timer allows you to temporarily or
periodically raise or lower the room temperature. When
the contact is on, the heat curve offset is changed by
the number of steps selected in the menu. If a room
sensor is installed and activated the desired room
temperature (°C) is set.
If there is more than one climate system the setting
can be made separately for each system.
Menu 1.9.3 - min. flow line temp.
climate system
Setting range: 5-70 °C
Default value: 20 °C
Set the minimum temperature on the supply temper-
ature to the climate system. This means that VVM 310
never calculates a temperature lower than that set
here.
If there is more than one climate system the setting
can be made separately for each system.
TIP
The value can be increased if you have, for ex-
ample, a cellar that you always want to heat,
even in summer.
You may also need to increase the value in
"stop heating" menu 4.9.2 "auto mode set-
ting".
Menu 1.9.4 - room sensor settings
factor system
Setting range: 0.0 - 6.0
Default value: 2.0
Room sensors to control the room temperature can be
activated here.
Here you can set a factor that determines how much
the supply temperature is to be affected by the differ-
ence between the desired room temperature and the
actual room temperature. A higher value gives a
greater change of the heating curve's set offset.
If several climate systems are installed the above set-
tings can be made for the relevant systems.
Menu 1.9.7 - own curve
supply temperature
Setting range: 0 – 80 °C
You can create your own heating curve here, if there
are special requirements, by setting the desired supply
temperatures for different outdoor temperatures.
Caution
Curve 0 in menu 1.9.1 must be selected for this
curve to apply.
Menu 1.9.8 - point offset
outdoor temp. point
Setting range: -40 – 30 °C
Default value: 0 °C
change in curve
Setting range: -10 – 10 °C
Default value: 0 °C
Select a change in the heating curve at a certain out-
door temperature here. One step is usually enough to
change the room temperature by one degree, but in
some cases several steps may be required.
The heat curve is affected at±5°Cfromsetoutdoor
temp. point.
It is important that the correct heating curve is selected
so that the room temperature is experienced as even.
