Figure 3: RHE21 Wiring with RHM Connection Types J6 & JO
Upon power up, if the RHE indicates an error and the temperature measurement on the bottom
right of the display shows “ -.--°C/°F ” please check the temperature measurement configuration
setting in the RHE (section 4.5).
The correct temperature measurement configuration setting for an RHM with connection type
JO is “3”.

Connection only necessary for RHE21 construction types E5 and H3 without integrated sensor cable.

The shield of the cable is connected to the housing of the RHM using a screw terminal in the junction box. If there
is a risk of a significant potential difference between the housing of the RHM and the PE terminal of the RHE, the
shield should be connected to the RHE PE connection via a 1nF capacitor. Alternatively, a separate cable can be run
for potential equalization between the RHM case and the RHE and the shield left both unconnected and isolated at
the RHE or terminated to the PE connection via a 1nF capacitor.
