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.

Zone Control Status Connected
When the Zone Control is connected adjustable settings are automatically shown under the Adjust
“Modulation”, “Auxiliary Heat” and “Zone Control Description Setup” menus. This feature allows these
adjustments to be made before the zone panel is connected. When the user selects “Show As If
Connected” Zone Control related parameters are made visible and may be adjusted.
Enabled Enable/Disable
Frost Protection
Disable Frost Protection is not used.
Enable Boiler circulator starts and boiler fires when low outside air, supply and return
temperatures are sensed as follows:
0 min. 0-20 min.
anti-Short Cycle Time
Anti-short cycle is a tool that helps prevent excessive cy-cling 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.
