D. OPERATING DESCRIPTION
The master NAVISTEM B3100 controls the cascade of boilers on the basis of the outlet
temperature measured by the sensor QAD 36. Each NAVISTEM B3100 controls the charge
pump of its own generator.
The boilers operate with a variable outlet temperature according to the outdoor temperature
measured by the sensor QAC 34, temperature adjusted according to the most demanding
circuit, without parallel offset, without a low temperature limit and with a weekly programme.
The heating programme is per week. Each AGU 2.550 module controls a regulated circuit with
a 3-way valve.
