Alternatively to the sensor dry wells the M2 - M5 sensor
tension brackets can be used to install temperature sen-
sor on the outside of the DHW tank shell.
Make sure to sensing elements are fully in-
serted into the wells and that they make good
surface contact.
V Use heat conducting paste to improve contact.
V Slide sensor surface behind tension bracket to ensure
that the entire sensor surface is in contact with the tank
shell.
V Carefully route the sensor wiring.
