Installing the outdoor sensor:
Position the outdoor sensor (TMO) in a shady pla-
ce on the northern side of the building at a height of
about 2.5 meters. Do not install the sensor directly
above a window, door, vent or sensor cable protecti-
on tube coming from indoors, or next to an exhaust
duct or any other source of heat. If necessary, the
cable can be either shortened or lengthened using a
screw connector. (No special requirements for cab-
le type). The controller uses an outdoor temperatu-
re setting of 0° C if the outdoor sensor has not been
connected.
Connect the cord and connecting box if you
take something that is not included in the basic
package into use :
The cord and connecting box can be used to connect
2 different things (measurements 3 and 4). Open the
connecting box and make the necessary connections
(see page 23-25).
Connecting the power source:
Plug one end of the cord into the wall and the oth-
er end into the controller. We recommend putting
the cord in a protective sleeve. Put the connec-
tion space’s protective cover back into place.

Cut the corner of the bag open and squee-
ze the grease on the bottom surface of the
sensor on the copper plate.
Wrap the fastening strap around the pipe.
Make sure that the surface sensor is not
loose.
Wrap the strap around the pipe again if it
is long enough. Cut the strap to the pro-
per length along the groove between the
holes.
Detach the protective cover of the controller’s connection
space (slides off at a right angle to the controller) and connect
the outdoor sensor to the controller.

Installing the supply water sensor on the pipe:
Fasten the surface sensor to the surface of the pipe entering
the network about 0.5...1.5 m from the valve either on the top or
side of the pipe. The surface of the pipe should be clean, rust
free and smooth; the pipe can be painted.
