Outdoor Air Sensor Calibration
Outdoor Air Sensor Calibration offset allows a single point calibration. Using a reliable source (reference)
for outdoor temperature measure outdoor air temperature. Set the offset equal to the difference between
the controller reading and the reference. The result will be the Control’s measurement matching the
reference reading.

anti-Short Cycle Time
Anti-short cycle is a tool that helps prevent excessive cycling resulting from a fast cycling Thermostat or
Zone valves. It provides a minimum delay time before the next burner cycle. DHW demand is serviced
immediately, without any delay.
Disabled
Enable/Disable
Warm Weather Shutdown Enable
Disable Warm Weather Shutdown (WWSD) is not used.
Enable The boiler and pumps will not be allowed to start in response to a central heat call for heat if
the outside temperature is greater than the WWSD setpoint. WWSD is initiated as soon as
outside air temperature is above WWSD Setpoint. The control does not require call for heat
to be satisfied.
The boiler will still start in response to a Domestic Hot Water call for heat.
