Maximum Firing Rate of all Connected Boilers
FAN SPEED
- Output is proportional to boiler fan speed. 0V
= Fan is Off, 1.5V = Minimum Fan Speed, 10V = Maximum Fan
Speed
ALARM
- 0V = Alarm is Off, 10V = Alarm is On
TEMPERATUR
- Output follows boiler temperature setting
based on outdoor reset. 0V = Minimum Boiler Temperature
for Maximum Outdoor Temperature Setting. 10V = CH (or
cascade) temperature setting. This number will vary with the
outdoor temperature so that the user can know what setpoint
temperature the boiler is trying to achieve.
FLAME
- Equals boiler Flame Current. 0V = 0ua, 10V = 10ua.
