THRV 22 DOUBLE TEMPERATURE CONTROLLER
APPLICATION
This double thermostat monitors the temperature in the switching cabinet. It was specially developed to control the combination of fan and heater. It is two independently switching thermostats with a high switching capacity in a compact housing.
FEATURES
- Temperature controller for fan and heater
- 1x NC contact at rising temperature to control the heater
- 1x NO contact at rising temperature for regulation of the fan
- High power capacity
- Adjustable temperature 0 – 60 °C
- Mounting on DIN rail
- 10 A switching capacity at 250 V AC

MOUNTING/INSTALLATION
The controller is mounted on a 35 mm DIN standard rail. For this purpose, the controller is hooked in with the upper hooks and then snapped onto the standard rail by pressing. To remove the controller from the standard rail, first pull it down and unhook it from the front.
The THRV 22 has internal sensors. In order to record the actual internal temperature of the control cabinet, it must not be directly exposed to cold or heat sources, unless it is the assembly to be protected. After mounting, the controller must be wired as shown in the wiring diagram.
After installation, therefore, the correct operating direction and proper functioning of the control must be checked. The switching point is set with a slotted screwdriver.
Mounting
- Hook up at the top
- Snap on below
Removal
- Pull downward
- Unhook inclined manner
