The ULTRAVAC™ control manages the CORAYVAC® infrared heaters. The controller has the ability to modulate burner input rate with outdoor air temperature to match the heating system’s input to the building’s heating requirement, states the company. Modulation of the burners in series occurs by varying vacuum and adjusting gas and combustion air equally, which is intended to ensure proper combustion. The zone temperature sensor is designed to provide localized control. Heating system management can be performed via a PC-based software package; the optional modem provides the ability for remote system management.
