Button: MENU/<System Startup>/..../Switch Setpoint/Switch Diff/Switch Delay
• The Switch Delay is an additional layer of assurance used to reduce the intermittent change
of the lead group.
• To switch the lead group when the temperature is dropping, the sensor temperature must
remain below the Switch Set Point less the Switch Differential for the complete Switch
Delay period before the switching of the lead group.
• I.e., if the Switch Set Point was set to 135ºF, and the Switch Differential was set to 5ºF, then
the Target Temperature must drop below 130ºF for the complete Switch Delay for the lead
group to change from Condensing to Non-Condensing.
• To switch the lead group when the temperature is rising, the Target Temperature must rise
above the Switch Set Point for the complete Switch Delay before the switching of the lead
group could take effect.

Button: MENU/<System Startup>/..../Switch Delay/Heavy Load Seq#2 Group
• This option makes the second group of boilers act as a backup in heavy load conditions.
Thus, allowing them to start after all lead group boilers have run at their maximum capacity.
• If the system was designed to operate both groups of boilers in heavy load conditions, then
select Yes.
• Selecting No will only allow the lead group to operate. The secondary group will remain off
even if the system cannot reach the desired set point.
