ROTATE CYCLES
: Set the number of cycles at which
you would like to rotate the boilers. One cycle is
described as the boiler going on and then off.
(OFF/1 to 240)
NUMBER OF MOD STAGES
– This setting will allow you to
select the number of modulating stages.
MODULATING TIME
– This setting sets the time
between the steps when the boiler needs to increase
or decrease the firing rate. Each step is 1% for all
situations.
(1S to 240S)
MIN MOD PERCENT
– This setting is used to set the
lowest modulating level the boiler can go down to.
This will also be the starting point whenever there is a
new demand.
(1% to 99%)
MOD OUT SETPOINT
– In this mode the 0-10VDC signal
does not directly run the burner. The 0-10VDC signal
is interpreted by the boiler as a setpoint. The boiler in
this mode will modulate the burner to achieve that
setpoint. ex: 4VDC is equal to 140°F
(ON/OFF)
STAGING MODE: BOILER SETUP
If you select more than three (3) stages you will need additional(s) CPU-0600
as the CPU-0600 can do a maximum for three (3) modulating stages per
controller.
If you are using modulating boilers and On/OFF boilers together in a system the
modulating boiler(s) will stage first.
