The IQL11+ 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 1 relay output (normally fan on/off), and 4 triac outputs (normally to control valves or dampers). It has 2 variable resistance inputs of which one is normally a thermistor temperature sensor. There is also a digital input for monitoring a manual button or alarm contact; it can also be used to connect a room display.
