The functional diagram of VMF-CRP expansion is described in fig. 8. As indicated in the diagram, the control can manage:
— A boiler
— Three heat recovery units
— Three V.O.C. probes (room probes that are able to detect the following gases in the air: carbon monoxide (CO), sulphur water (H2S), solvent vapours, alcanoli vapours,
cigarette smoke, exhaust fumes from cars, air produced by human breath, smoke of burning wood, paper and plastic materials)
Functional diagram of VMF-CR expansion
The boiler is enabled for functioning when one of the following conditions occurs:
— no heat pump
— heat pump in standby
— heat pump forced off due to external air temperature
— heat pump in alarm (for the Multicontrol system all heat pumps must be in alarm)
The contact closes, instead, when the control detects at least one request for hot functioning from the thermostats of the VMF family or from a zone controlled by MZC or from
a thermostat digital input associated with VMF-REB 1/2/3 expansions.
