its original operating parameters.
Temperature Units (°C/°F)
The control can be configured to display temperature in
either °C or °F. This parameter can be changed by accessing
parameter u01.
Set SH Temperature
The Space Heat Demand Temperature can be adjusted UP or
DOWN by accessing parameter u02. Temperature range is
32°F to parameter P90.
Set tank DHW Tank Setpoint (if tank sensor present)
The DHW Setpoint Temperature can be adjusted UP or
DOWN by accessing parameter u03. Temperature range is
60°F to 185°F.
Set SH Setpoint at Minimum Outdoor Temperature
When the outdoor air temperature drops to 25°F, the
calculated set point will be at this setting (reference Table 4-3
in the Cadet Heating Boiler Installation and Service Manual).
If the outdoor air temperature drops further, the set point
will continue to increase above this setting. However, if SH
set point is set lower than the calculated set point, the water
temperature will be limited by the SH set point instead. This
parameter can be changed by the installer by accessing the
P01. Temperature range is 68°F to 250°F.
