Applications
These waterproof control boxes with wall mounting allow remote control of the surface temperature of the pipes.
The connection to the heating elements is via a connection box with or without offset mounting foot type Y26, Y27, Y28, Y29, or with a 3-conductor power cable and a separate NTC temperature sensor cable, or by an offset mounting foot connection box type Y29B and a single 5-conductor cable equipped with a 5-way connector.
The use this model with digital display is simple and intuitive, and does not need specially trained users.
The use of a wired temperature measurement sensor, which can be disconnected, allows to overcome the problems of wall crossing of bulb thermostats, the capillary of which cannot be cut, and to proceed with installation of connection and control boxes after mounting the heating cables and the temperature sensor, installation of the pipe insulation and installation of the insulation protection sheath.
Main features
