1.6 Setting for Use with Boilers or Water Heaters
The Cascade Sequencer is set at the factory for boiler applications, but not for water heater
applications. When your system is in place, and you wish to control water heaters, you must
ensure all parameters of the Sub Menu are set as shown in the list in Section 2.1. Select the
settings in the column for boilers if you are using boilers, or select the settings in the column for
water heaters if you are using water heaters.
1.7 Dependent Heater Preparation – Setting Parameter 2003
Parameter 2003 is factory set to 0. However, this parameter should be checked for all
dependent heaters to ensure parameter 2003 is set to 0.
Follow the instructions in Section 1.71 (next page) to access the Installer Menu on the AM
Series boiler or water heater controller to confirm or change parameter 2003 to zero for all
dependent heaters. If you need more information concerning AM Series controller operation,
consult the AERCO AM Series user manual (GF-146).
