The 41001 Heat Pump Air Conditioner allows the O.E.M. to build and ship a complete unit ready for Ambulance Installation.
The 41001 will operate to an outside ambient of 40 degrees. At 40 (+/-2) degrees the outdoor thermostat will turn off the compressor (fan will continue to operate). As the outside temperature returns to 45 degrees, the outdoor thermostat switches the compressor back to on and heating will resume.
