Siemens TUTORbit POL895 - Installation; Choosing and Setting up the System

TUTORBIT
COSMOGAS
ATTENTION!!! If the DHW mode is “Thermostat”, the Anti-
legionella service cannot be completed. The installer must
take all necessary precautions to prevent the legionella
bacteria from growing in order to avoid seriously harming
the health of people or animals
NOTE! For correct operation of the system, if the hot
water tank is controlled by a thermostat, the DHW setpoint
(Parameters->DHW->DHW setpoint) must always be
higher than the thermostat setpoint.
ATTENTION!!! The parallelism of the tank lling with the
heating is only guaranteed with mixed heating circuits.
- Unit of measure
Select °C to display the units of measure according to the
international system. Select °F to display the units of measure
according to the imperial system.
- Number of Zones
Select the number of heating zones you want to control.
- Anti-legionella
Select “Yes” if you want to enable the anti-legionella service
or select “No”.
ATTENTION!!! Disable the Anti-legionella service can
seriously harm the health of people or animals.
- Shue pump type
This parameter controls a possible shu󰀪e pump installed on
the domestic hot water tank. It can be used for the “Tank load”
function when there are several hot water tanks connected in
series, or it can be used for the mix “Anti-legionella” function
when the hot water tank is also lled by a solar panel.
ATTENTION!!! With a solar zone, it is very important
to have an anti-legionella shu󰀪e pump that works. If
this pump is missing, the installer must use alternative
solutions to run the Anti-legionella. Not doing so, could
seriously harm the health of people or animals.
- Solar
Select “Yes” if you want to ll the domestic hot water tank also
using a solar panel, or select “No”
- Solar Antistagn.
Select “Yes” if you want to enable the Anti-stagnation function,
or select “No”
The anti-stagnation system tries to prevent the solar panel
from boiling, especially in the summer.
NOTE! Disable the Solar Anti-Stagnation system can
cause malfunctions in the lling system of the hot water
tank using the solar panel.
- Solar Antif.
Select “Yes” if you want to enable the solar antifreeze function,
or select “No” if you want to disable it.
ATTENTION!!! Disable the solar antifreeze system can
seriously damage the solar panels.
- Modbus enable
Modbus enable or not if you want to read the Modbus
parameters of the heat modules.

“Distributed power” conguration
Figure 4-10 shows the application diagram of a system where
all the heat modules are controlled in parallel to produce
heating, whereas a single module is intended to produce
domestic hot water. This system, where the power can be
distributed in a varied way to the DHW or to the heating, is
subsequently called “Distributed power”.
Figure 4-31 shows the application diagram of a system where
all the heat modules are controlled in parallel to produce
domestic hot water. In this case, the modules must be
“AGUADENS T” water heaters models.
4.7 - Installation
Install the TutorBit in the room where the heat modules are
installed or nearby, and follow all the electrical connections
shown in diagrams of Section 4.21.
4.8 - Choosing and setting
up the system
Some diagrams of the most common systems, with their own
electrical system and controller setting, are shown in Section
4.21.
To browse through the menus and edit a parameter, see
Section 6.4.
Using the Conguration->System menu, you can access
the following parameters to set up your system:
- Modules Qty:
number of heat module you want to install in cascade (from
1 to 4);
- Module 1
Indicates if heat module 1 is used to produce heating and
DHW in “All power” or “Distributed power” (Section 4.6).
- Module 2
Same function as Module 1, but refers to Module 2.
- Module 3
Same function as Module 1, but refers to Module 3.
- Module 4
Same function as Module 1, but refers to Module 4.
- Outdoor Sensor
Select “Yes” if you want to enable the outdoor sensor and all
its functions: antifreeze protection and climatic adjustment.
- DHW
Select “Yes” if you want to produce DHW with a storage tank.
- DHW return sensor
The DHW return zone can be controlled with the time
programme in the menu Parameters->DHW->DHW return
timer prog. However, if you want to control the return zone
also based on your temperature, select “Yes” in the “DHW
return sensor” parameter.
- DHW mode
Select “Sensor” if the hot water tank is controlled by a
temperature sensor. Select “Thermostat” if the hot water tank
is controlled by an On-O󰀨 thermostat.
