Precautions and
safety
Tom is equipped for connection on
M30x1,5mm radiator valves. Tom is
supplied with the adapter rings M28
and Danfoss RA. If your radiator is
suited with a different connection,
please contact your installer to see if
an adapter ring is available for your
system.
Do not install Tom with the USB
adapter if you want to use Tom
together with batteries. The battery
lifetime will reduce dramatically in
case you have installed Tom with the
USB adapter and then change to
battery power supply. Do you want
to switch the power supply later?
Remove Tom from the network and
re-add Tom to the network
connected to the right power supply.
Never install Tom with batteries and
USB-adapter at the same time!
When powering up Tom, it will try to
calibrate. Therefore, do not leave
Tom powered when it is not mounted
on a radiator.
Never mount Tom if the valve pin is
extended. Before mounting Tom on
the radiator, make sure that the valve
pin is fully retracted.

The valve pin is extended. First power up Tom as
described in step 2. When powering up Tom, it will
try to calibrate. Tom will be retracting and then
extending. Remove the power supply when the pin is
fully retracted.
