3 (COIL), 4 (CONV),
5 (RAD), 6 (BASE)
Default = 4
D1
Boiler Indoor - The design indoor air temperature
used in the heat loss calculation for the heating
system. 35 to 100°F
(2 to 38°C)
Default = 70°F (21°C)
D1
Boiler Design - The design supply water temperature
used in the heat loss calculations for the heating
system. 70 to 220°F
(21 to 104°C)
Default = 180°F (82°C)
A
Boiler Minimum - The minimum allowed boiler target
temperature.

B1
Fire Delay 1 - The time delay the control can expect
between the time that the relay contact closes to fire the
first stage of the boiler and the burner actually fires. 0:00 to 3:00 minutes
(1 sec increment)
Default = 0:10 min
B1
Fire Delay 2 - The time delay the control can expect
between the time that the relay contact closes to fire the
