your room thermostats

Introduction

The versatile RDG and RDF room thermostats help you to better meet your customer's needs.
The following information supports you in setting up your RDG and RDF thermostats.

Control parameters

A number of control parameters can be adjusted to optimize control performance and
enable additional functions, making it possible to employ. The RDG and RDF thermostats
in almost any type of application.
The control parameters are assigned to 2 levels:
– Service level and
– Expert level
The service level contains a small set of parameters to set up the thermostat for HVAC
systems (control sequence) and to adjust the user interface.
The expert level contains control parameters for fan, control inputs/outputs and other
functions. Take care when changing parameters on the expert level as these changes
impact the thermostat's control performance and functionality.
As a rule, you don´t need to adjust parameters once the required application is selected
TIP
via the DIP switch since the thermostat works correctly using factory set parameters. It may
be nevertheless necessary, in some cases, to adjust application specifi c parameters.
– Control sequence (P01):
– Multifunctional inputs (P38...P42):
– Control outputs (P46...P47):
– Fan function (P52...P62):
