b. Similarly, the WWSD Temperature set on the
master boiler will prevent any boilers from
operating for a CH demand when the outdoor
temperature is above this value.
7.
Multiple Boilers – Ramp Delay:
a. The ramp delay feature can be set on each
individual boiler.
b. However, it is important to note that since the
dependent boilers treat DHW demands as a CH
call, the ramp delay will take effect even when the
DHW tank calls.
8.
Multiple Boilers – Anti-Cycling:
a. The Anti-Cycling feature is active on all boilers
unless it is disabled.
b. This will prevent dependent boilers from operating
within the prescribed time limit. However, it will
only prevent the boiler from cycling on its own
limit. Repetitive calls from the master boiler will
result in cycling.
9.
Multiple Boilers – DHW Operation:
a. Since the DHW tank sensor or thermostat is
connected only to the Master boiler, this is the
only boiler that will receive the DHW demand.
b. The master control will start boilers as necessary
to meet the demand.
c. Boilers with a boiler address of 2 or higher will
automatically be switched to DHW Mode 0 (No
DHW).
