trol operates the boiler burner to maintain the boiler target at the boiler outlet sensor.

Mode 7 – Designed for an external input signal with primary/secondary piping. The external input signal can be provided from a BMS, an EMS or an external control. The external input signal changes the boiler target according to a linear scale (see Tables O & P). The control operates the boiler burner to maintain the boiler target at the system sensor. See Fig. 35.
