03 · DESCRIPTION

Purpose and operating principle

The module handles the initial filling of the secondary heating loop and compensates for operational losses of heat carrier. Control is by pressure-sensor signal: when pressure drops below the set point, the module starts the pump and tops up the water until the rated regime is restored. Pump control is on/off, variable-frequency, or variable-frequency per pump (VFD-per-pump).

04 · APPLICATIONS

Where the module is used

Indirect (closed) heating systems requiring compensation of heat-carrier losses
Loops with an expansion tank and a defined static pressure
Initial filling of the secondary loop at system commissioning
