Service
To gain access to the service level, you have to enter a password (code). It is 6-7-8-9, and it
cannot be changed.
Access to the service level can be prevented by sealing the mode switch.
In the service level, the controller is matched to the task in hand by making these entries,
amongst others:
configure and (if necessary) adjust the measured-value inputs
set the control actions and modes of action
configure the control outputs
In the parameterising procedure described below, the grey fields contain the values that have
been entered at the factory (default values).
They should be considered as examples and apply for control model 0.
All entries and changes should be performed with great care. If the controller fails to
work properly, the cause is often incorrect configuration, e.g. the wrong mode of action
or the wrong type of transmitter.

Description of functions: RDT 300
Control model 0
Installation:
– dual pipe system, heating or cooling
Features:
– separate PI controllers for heating and cooling with 2 setpoints per controller
– free PI controller, e.g. for dehumidification
– switchover between heating and cooling by means of change-over signal
– change-over output to switch the room controllers over
– outdoor temperature averaged and damped, can be switched off
– flow temperature for heating is controlled by outdoor temperature, based on heating curve
– flow temperature for cooling with shift
– operating mode changeover is internal, or via external system remote control, off mode with
frost protection
– flooring function as per DIN 4725 part 4
– valve anti-jamming function
– pump blocking protection
– active dewpoint prevention using dewpoint controller (limiter), internal dewpoint calculation, optional
active dewpoint input
– change-over signal derived:
from outdoor temperature or
from the averaged outdoor temperature or
time-limited as a function of reference and outdoor temperature
– shift output can be parameterised, e.g. to room controllers
– week clock with automatic summer/winter time switchover
