SEQUENCER CONTROL OF MULTIPLE BOILERS
In installations where the heat load is greater than the
boiler capacity an ideal solution is to use multiple boiler
arrangements.
The ideal way to control a multiple boiler installation is
with our modulating sequencer
See below a typical installation with our modulating
sequencer kit. This device is capable of controlling up to
5 boilers. Additional kits are required for greater than this.
