Typical installation
System operation
The control panel randomly selects some heaters at the ready stage and some at the standby stage, and heaters will start dependent upon
water flow and temperature settings. The system rotates the lead and standby units after every eight hours operating time. As the flow rates
increases additional units will fire thus maintaining the required system flow temperature. The remote controller must be connected to Unit
No. 1 and temperature settings on this controller will be communicated to the other manifolded heaters on the system. The System Controller
is not required when the installation incorporates a storage cylinder/ buffer vessel or if a constant large volume of hot water is required.
