All models of VAV1xx have a footprint slightly larger than an FEC1611 controller. In the majority of applications, the replacement controller fits into the space previously occupied by a VAV1xx.

When used in a VAV box control application, the VAV1xx is typically connected to an EDA series actuator or an ATP series actuator/pressure transducer assembly. You need to replace both the VAV1xx and the EDA/ATP actuator with the VMA1832. The VMA1832 is mounted in place of the EDA/ATP actuator, so this dimensional comparison is key. The VMA1832 is slightly larger than the EDA/ATP. As a result, if you use a VMA1832 to replace a VAV1xx controller plus EDA/ATP actuator assembly, be sure to verify that enough space is available in the enclosure.
