General information
2 General information
2.1 Introduction
These operating instructions provide important information about handling
the electronic room thermostat. To allow safe working, all the specied safety
information and operating instructions must be adhered to.
The operating instructions must be read carefully before starting any work. They are
a part of the product and the company operating the system must keep them where
they can be accessed at all times.
2.2 Liability limitation
All of the data and information in these instructions has been assembled based on
the applicable standards and directives, the current state of the technology and our
many years of know how and experience.
The manufacturer will accept no liability for damage resulting from:
• Failure to observe the safety instructions
• Failure to observe the operating instructions
• Improper usage
• Use of untrained staff
• Unauthorised modications
• Technical changes
In all other cases, the obligations agreed to in the supply contract apply, as well
as the General Standard Terms and Conditions and delivery conditions of the
manufacturer, and the statutory regulations in force at the time the contract was
signed.
2.3 Intended use
The room thermostat controls, directly or via a control distributor, the connected
thermal actuators for unit valves in a unitary control system. Depending on the
model, it is suitable for 24 V or 230 V components.
Depending on the model, the device is suitable for
• xed installation
• recording the actual temperature (room temperature)
• setting the setpoint temperature
• controlling the actual temperature by activating positioning actuators in heating
or heating/cooling mode in an assigned area
• connecting an external sensor
All other uses, changes and modications are expressly forbidden and lead to risks
for which SAUTER is not liable.

Factory setting: 5 °C
Activates the frost-protection facility when the temperature falls be-
low the set temperature.
Setting range: 5 °C to 10 °C.
Activate the “optimised time programme” function.
Factory setting: 0
If the “optimised time programme” function is activated, the set-
point is reached at the dened time. In order to reach the setpoint,
heating or cooling mode is initiated in good time ahead of the de-
ned time.
0 = deactivated
1 = activated
Set the cycle time for the valve protection facility.
Factory setting: 14 days
Prevents the plug from sticking inside the valve.
Setting range: 0 to 28 days
Determining a pilot clock output.
Factory setting: 0
0 = Pilot clock output active by time program
1 = Pilot clock output is inactive according to time program
Pilot clock output active when operating mode “ECO” is slected;
Pilot clock output active when operating mode “Off” is selected
Note: If parameter P230 = 1, the time program for local reduced
temperature can be used.
Dening the actuation duration while the valve protection facility
is active.
Factory setting: 5 minutes
The actuation time can be optimised depending on the running
time of the thermal actuator.
Setting range: 0 to 10 minutes.
Change the service code for the service menu.
Factory setting: 1234
Note: In order to avoid unwanted access to the service parameters,
we recommend that the service code be changed by the installer
