IQL15 + is a controller for air conditioning devices, designed to work in the LonWorks (Lon) network. It can communicate with other IOL and LonMark devices via the Lon bus, and with the IQ system network devices via the LINC or 3XTEND / EINC L communication module.


The controller has 3 relay outputs (standard fan speed control) and 4 triac outputs (standard valves or dampers control). The fourth relay is used as an output to the electric heater (version / E) or as an additional output (version / AUX). It also has 3 inputs for variable resistance components, the first of which is normally used for a thermistor temperature sensor. The controller also has 2 digital inputs monitoring manual buttons or alarm contacts. One of them (IN4) can also be used to connect a room display.
