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
