The IQL14 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 devices via a LINC unit. It has 4 relay outputs (normally 3 are to control fan speed and normally one is to switch an electric heater) and 4 triac outputs (normally to control valves or dampers). It has a variable resistance input which is normally a thermistor temperature sensor.
