Floor Standing Condensing Boiler Unical

Optional accessories:
Acid condensate inhibitor
Primary circuits: hydraulic system interface with additional safety devices and modulating pump.
Mixing header
all weather: stainless steel protection for outdoor installation.
External Cascade Manager. (Cascade installation of 2 or more MODULEX)

Efficiency class **** in according to EEC 92/42 directive
Each module, is composed of a combustion chamber, metallic fiber pre-mix burner, modulating fan, gas valve, ignition electrode, flame detection, NTC sensor for management control (BMM), local temperature control and safety thermostat.
Each single boiler is equipped with NTC sensors for global temperature control on the flow and return manifolds.
Integral, non allergic, synthetic wool insulation.
Fully pre-mixed, radiating, modulating, metallic sponge burner, Automatic no return diaphragm for separation from combustion chamber.
Combustion air intake system from boiler house (type B 23 appliances) or directly from outside the boiler house, via an air duct (type C 63 appliances)
Possible cascade installation of 2 or more MODULEX
Heating Operation: setting of instantaneous output by a main microprocessor, with a comparison parameters presetting between the requested temperature (or calculated by the outer compensator) and the global flow temperature.
Logic of operation:
A. Output sharing on as many modules as possible at min. load (down to 12 kW) for the max. efficiency.
B. Automatic operation hour splitting-up system for each module to guarantee the best homogeneous use.
C. D.H.W. production, via a storage tank loading pump or a three way diverting valve, controlled by a priority sensor through the E 8 heating controller.
D. Output check of each module for any calibration and/or assistance by secret access code.
Possibility of controlling the output of each single module (BCM - Modbus)
A. Heating request control: temperature set point and modulation level.
B. Monitoring of boiler and temperature status.
C. Alarm control.
D. Parameters setting.
Relay for control of the operation of a pump at constant flow rate.
