A thermostat monitoring and controlling the temperature of produce ripening within an enclosure and featuring a bridge circuit sensing errors between the actual and desired temperatures in which the desired temperature is selected directly in units of degrees. A bridge amplifier having feedback maintains the bridge in electrical balance to avoid errors due to changes in bridge component self heating. An error detection circuit having a single control simultaneously selects upper and lower error limits centered on the desired temperature, in units of degr...
A temperature monitoring and control circuit for monitoring the temperature of products within an enclosure which can have various critical temperature characteristics, comprising a bridge circuit formed by temperature sensing and reference branches that provide respectively temperature signal and reference signal outputs, said bridge circuit including means to vary a desired set point temperature at which said outputs are equal, a bridge amplifier having as inputs said temperature signal and reference signal outputs and constructed to generate an error ...
