One Stage Steam Control 269

06/00
The tekmar One Stage Steam Control 269 is a microprocessor-based control which regulates the
firing time of a steam boiler based on user settings, outdoor air temperature, condensate return
temperature, and optionally, the indoor air temperature(s). The steam boiler can be operated in
the outdoor reset mode, or in Manual Override mode based on dial settings. The control has built-
in diagnostics for sensor checking with a Warning output for error reporting. Other control
operation features include Auxiliary relay output, Steam Established and Lockout Differential
temperatures, and Early Start with setback limit when using the Unoccupied input.
