2.2 Cascade Status Button
By pressing the Cascade Status button (Figure 2-1), the lower half of the display will change to
show the status of the cascade boilers (Figure 2-2). The designated number for each boiler in
the cascade system will be displayed, such as 1, 2, 3, 4, etc., up to 8. If there is a request for
heating for any heater, a flame icon will appear under that heater’s number. The absence of a
flame icon under the number represents a heater in standby mode. If there is a fault, a “wrench”
icon will be displayed under the heater’s number.
The Cascade Status display shown in Figure 2-2 indicates there are three heaters in the
cascade, with numbers 1 and 2 calling for heat, and number 3 in standby mode.
NOTE:
Due to the slow communication protocol, it may take up to 40 seconds for the Cascade
Status screen to update the status of an individual
boiler or water heater.
