NOTICE
The CSD-1 ASME Code, Section CW-400 requires that hot water heating and supply boilers have a) a UL 353 temperature control
device, b) at least one (1) temperature-actuated control to shut off the fuel supply when system water reaches a preset operating
temperature, c) a high temperature limit control that prevents the water temperature from exceeding the maximum allowable
temperature by causing a safety shutdown and lockout, and d) its own sensing element and operating switch.
The temperature control system integrated into the 926 control provided with this heating appliance complies with the requirements of
CSD-1 Section CW-400 as a temperature operation control. The control monitors the temperature difference between the inlet and the
outlet sensor, which is affected by boiler water flow. If this temperature difference exceeds 55°F (typically because of low water flow or
very low heat load), the control will reduce the maximum fan speed. If the temperature difference exceeds 60°F, the control will
effectively sense there is little or no water flow or heat load and shut the boiler down. The controller will restart automatically once the
temperature difference has dropped below 55°F and the minimum off time (anti-cycle time) has expired. In addition, if the control
senses that the outlet water temperature has reached 210°F, the boiler is put into a hard lockout and requires manual reset to restart.
