1. Applications
This electronic temperature controller is designed for con-
trolling the room temperature in conjunction with:
• heating systems e.g. hot-water heaters, convector heaters
or floor heating
• Heating cooling change over in combination with
connection strip and suitable input
• circulation pumps
Features
• PWM-Output (TPI)
• Relay change over contact
• Heater switch (stand-by, controller remains on mains,
load will be switched off)
2. Description of functions
2.1 Functions
The room temperature is measured by the integrated
sensor and is set via the dial.
2.2 Remote sensor
For measuring the room temperature a remote sensor can
be used instead of the internal one.
If the remote sensor is connected, the internal one
automatically will be disabled.
In case of sensor error the internal sensor will be used.
3. Mounting / Commissioning
The controller should be mounted at a point in the room
which:
• can be easily accessed
• is free of curtains, cabinets, shelves, etc.
• allows free air circulation
• is not exposed to direct sunlight
• is not draughty (when doors or windows are opened)
• is not directly influenced by the source of heat/cold
• is not located on an outer wall
• is approx. 1.5 m above the floor.
Caution!
The device may only be opened and installed ac-
cording to the circuit diagram on the device or these
instructions by a qualified electrician. The existing
safety regulations must be observed.
In order to comply with safety class II, the necessary
installation steps must be taken.
This independently mountable electronic device is desi-
gned for controlling the temperature in dry and enclo-
sed rooms only under normal conditions.
The device confirms to EN 60730, it works according
operating principle 1C

Operating Instructions
Electronic room temperature controller
with PWM-Output (TPI)
RTR R1w, 517 1241…
Electrical connection
Perform the steps described below:
• Pull off the temperature dial
• Release the fixing screw
• Remove the upper part of the casing
• Connect acc. to circuit diagram (see inside cover)
Remote sensor F 193 720 or F 190 021 (as accessory)
Do not install the sensor close to mains cables. In other
cases a shilded cable has to be used.
The sensor can be extended to max. 50 m by means of a
cable suitable for mains voltage.
Caution! Sensor leads carry mains voltage (230 V).
