Siemens

The Siemens 192-840 Powerstar Retroline Retrostat Pneumatic Room Thermostat converts most existing pneumatic room thermostats to a Powerstar 192 direct acting, 2-pipe, single set point unit. The Day/Night or Heat/Cool Retrostat is factory-calibrated to match the appropriate changeover pressure of the competitive thermostat.

The complete kit includes a Retrostat cover kit with exposed or concealed set point adjustment, set point dial in Fahrenheit scale, factory-calibration for accuracy, all installation hardware and calibration wrench. The kit fits into large format wall openings, using ?goof plate,? which is included, as are integral, field adjustable limit stops, a test port for fast check of output pressure without removing the cover, field replaceable thermometer, set point dials, restrictors, and filters. Standard case cover color is Desert Beige.
