Compact air-air rooftop units
PJ range
Natural or propane gas burner with modulating actuator, in accordance with the Gas Directive 2009/142/EC, installed inside a pre-assemby roofcurb (optionally supplied with the unit). Condensation boiler with premixing and modulation technology that allows outputs close to 109% with regard to the lower heating value (LHV).

The electronic control manages its connection, in heating mode, via an ON/OFF signal. On cooling-only units, the control activates the burner in the same way as an electrical heater stage. On heat pump units it is possible to select three different operating modes: • As a backup for the compressors as an electrical heater stage. • Instead of the compressors. • Instead of the compressors if the outdoor temperature is less than the value marked on an outdoor thermostat. The power control is carried out by the burner’s own control in accordance with the signal received from the unit control. Note: It is recommended to use the clogged filter detection and anti-freeze protection options for the components of the electrical cabinet when outdoor temperatures are low (compulsory if the outdoor temperature is lower than -10ºC WB).
