The following tables are the individual sections of the Installation configuration menu in the
sensoCOMFORT controller. Only the modifiable parameters are listed as some items displayed are
read only, please consult sensoCOMFORT installation and servicing manual for further descriptions
of read only items if required.
If a specific diagram has been produced for the installation then any settings relevant for that
particular installation should be used in replacement of the below suggested settings.
This menu can also be accessed by the main menu – settings – installer level- access code 00 –
installation configuration.
Installation
Parameter Select/Display Factory setting Suggested Setting Remark
Adapt. heat curve - Deactivated
- Activated
Deactivated Deactivated
If operation explained
to customer then
being activated can
optimise the system
and aid efficiency.
Adaptive heat curve will adjust the
heat curve automatically based
on how quickly the target room
temperature is reached. This newly
determined heat curve is saved for
the next heating cycle.
Dependant upon the adjustment and
weather conditions on the previous
heating cycle having this parameter
activated can cause an over shoot on
actual room temperature. Explanation
is required to the end user.
Automatic cooling - Deactivated
- Activated
Deactivated Deactivated unless
cooling possible
for installation and
coding resistor has
been fitted
If Parameter = “Yes” has been
selected, cooling mode starts with
the stored control algorithm
Cooling at outdoor
temp.
10 – 30 °C 15 °C As per cooling
requirements
Minimum temperature from which
the cooling mode is enabled.
Source regeneration - No
- Yes
No No for awhp
applications
If Parameter = “Yes” is selected,
automatic cooling remains activated
even during programmed absences.
To do so, the “Automatic cooling”
parameter must also be set to
“Activated”.
Hybrid manager - triVAI
- Bivalence pt
Bivalence pt Biv point unless
hybrid system then
should select triVAI
Heating bivalence
point
-30 – 20 °C 0 °C Property dependant,
set temperature
when back up heater/
appliance will be
required for parallel
operation. If no back
up installed then set
to -30°C
Parallel operation with an additional
heat generator is enabled below the
temperature set here.
DHW bivalence
point
-20 – 20 °C -7 °C -20°C unless heat
pump is too small for
cylinder
Parallel operation with an additional
heat generator is activated
immediately below the temperature
set here.
Alternative point - Off
- -20 – 40 °C
Off Off unless hybrid
system and can set
the outdoor temp
when the heat pump
turns off and runs on
back only
Entering the alternative point sets
the outdoor temperature below
which the heat pump switches off
and the heating demand is covered
by the back-up heater only
