Installation heat calculator
ZENNER recommends to mount the calculator
RQWKHZDOO'RQRWPRXQWWKHGHYLFHDWWKHSLSHRUDWWDFKLWGLUHFWO\RQWKHÀRZVHQVRUThe mounting adapter at the backside of the cal-
culator can be used for rail mounting or “reverse”
for wall mounting.
For wall mounting attach the adapter with at least
two screws to the wall and clip the calculator on
it.
For rail mounting lift the adapter a little bit, place
the calculator on the rail and push the adapter
back until it locks.
Connection sensors
The mounting of the temperature sensors should
be done symmetrical with direct immersion. If
immersion sleeves are used they have to be
