The IQL17 is a terminal unit controller which can be networked using LonWorks (Lon). It can communicate with other IQLs and LonMark devices via the Lon, and with IQ system networked devices via a LINC unit. It has 3 relay outputs (normally to switch a fan and control electric heaters), two triac outputs, and one 0 to 10 V analogue output (normally to control a valve or damper). It has 3 variable resistance inputs (of which the first is normally a thermistor temperature sensor), one 0 to 10 V analogue input, and 2 digital inputs for monitoring manual buttons or alarm contacts.

The IQLVAV is a terminal unit controller with integral actuator which will clamp to the damper drive shaft. It can be networked using LonWorks (Lon) and can communicate with other IQLs and LonMark devices via the Lon, and with IQ System current loop networked devices via a LINC unit. It has 5 universal inputs, one of which can be linked as a TBus connection (for use with RD), as well as an integral differential pressure sensor (0 to 2 inwc; 0 to 500 Pa). It has five digital (triac) outputs.
