Function
Intended purpose
The room temperature controller is used to regulate the temperature in closed rooms such as fcats, schools, function suites, workshops, etc.
Product characteristics
Neutral conductor required
TR 231 U / TR 241 U:
- Separate terminal for temperature reduction of 5 K (e.g. during night time)
- -ON/OFF switch with status LED
- -When set temperature is reached the contact opens up.
TR 236 U / TR 246 U:
- -No OFF-position
- -Without switch and control LED
- -When set temperature is reached the NO/NC contact switches over.
Information for electrically skilled persons
- Mount the room temperature controller on an internal wall opposite the heat source if possible.
- -Do not mount the room temperature controller on the outside walls.
- -Avoid draughts from windows and doors.
- -Ensure that the normal air circulation in the room reaches the controller without any obstacles.
- –External heat sources influence the accuracy of the controller. Avoid direct sunlight and do not place heat-emitting devices in the vicinity of the room temperature controller (heaters, lamps, etc.).
- -Dimmers also generate heat.
- If a controller is installed in a common switch frame with a dimmer, the distance between them should be as great as possible. When arranging them vertically, the controller must be installed underneath the dimmer.

Installation
- Mount the room temperature controller in a switch box in accordance with DIN 49073.
- Mounting height: approx. 1.5 m above the floor
- Clip the rocker (4) on the switch in the flush insert.
- Place the center plate together with the frame on the flush insert.
- The center plate must snap in place in the top left of the housing base.
- Tighten the screw (5).
- Clip on the setting knob (6).
Operation
Restricting the temperature setting range
The temperature controller is set to ex-works to the maximum setting range of 5 °C to 30 °C.
Procedure
- Select the temperature limits.
- Example: min 8 °C, max. 23 °C
- Important!
- First position the setting knob roughly in the center of the required setting range.
- Example: The center point between 8 °C and 23 °C is approximately 15 °C.
- Now remove the setting knob.
- Set the red locating ring to the max. temperature limit.
- Example: 23 °C
- Rotate anti-clockwise.
- The numbers on the outer dial apply!
- Insert the tip of a pen in the hole and turn the red ring to the left until it reaches 23 °C (max. scale)
-
Set the blue locating ring to the min. temperature limit.
-
Example: 8 °C
-
Rotate clockwise.
The numbers on the inner dial apply.
Insert the tip of a pen in the hole and turn the blue ring to the right until it reaches 8 °C (min. scale).
-
Clip on the setting knob.
-
The pointer must be roughly in the center of the new setting range.
-
Example: approx. 15 °C
scale for setting the temperature with dials
- 1 = approx. 5 °C
- 2 = approx. 10 °C
- 3 = approx. 15 °C
- 4 = approx. 20 °C
- 5 = approx. 25 °C
- 6 = approx. 30 °C
Symbols
- O OFF
- I On
