In menu 1.9.3 you select heating or cooling, in the next
menu (min. supply temp.heating/cooling) set the minim-
um temperature on the supply temperature to the cli-
mate system. This means that F1355 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
example, 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 setting".
MENU 1.9.4 - ROOM SENSOR SETTINGS
factor system
heating
Setting range: 0.0 - 6.0
Factory setting heating: 1.0
cooling (accessory required)
Setting range: 0.0 - 6.0
Factory setting cooling: 1.0
Room sensors to control the room temperature can be
activated here.
Caution
A slow heating system such as underfloor
heating may not be suitable for control using
the installation’s room sensors.
Here you can set a factor (a numerical value) that determ-
ines how much an over or sub normal temperature (the
difference between the desired and actual room temper-
ature) in the room is to affect the supply temperature
to the climate system. A higher value gives a greater
and faster change of the heating curve's set offset.
NOTE
Too high a set value for "factor system" can
(depending on your climate system) produce
an unstable room temperature.
If several climate systems are installed the above set-
tings can be made for the relevant systems.

ORY REQUIRED)
