Solar controller are available in two types. A stand alone controller (TR301) or an add-on module (FM244) for use with the Buderus LogaMatic 2107 boiler controller. The wall mounted TR301 stand alone control features LCD readout and full operating display along with diagnostics. The TR301 oper- ates independently to cycle the pump module as storage temperatures in the solar tank drop. The control monitors temperatures from a sensor in the tank, and at the collectors to determine optimal operation. The FM244 module plugs into an existing 2107 LogaMatic control to provide optimal operation of the solar system and the boiler. Temperature sensing thermisters included with both controls.
