4.3 Setting up an external control load
To set up external control (BMS) to manage a desired boiler set point:
1. Go to > Advanced Setup.
If the boiler has never been programmed, all loads will be set to "Off".
2. On the Select a load screen, choose Ext. Control > OK. The settings screen is populated with
pre-programmed values appropriately selected for typical residential applications.
3.
In the Burner on from field, choose either Thermostat or Ext. Control.
If set as "Thermostat" (dry-contact enabled), the boiler will wait for a call for heat from
the thermostat terminal associated with the load, and then look at the Ext. Cont.
terminals for the target water temperature signal.
