Upon reaching an elevated temperature or CO2 level, the Midtherm i-Window system will automatically open a building’s windows in order to maintain comfortable room conditions. The i-Window system can be programmed to work alone or in conjunction with other natural ventilation options. The Midtherm i-Window System that regulates the control of a building’s windows, allowing the effects of natural ventilation to be optimised.

i-Window Zone Control

The i-Window controls systems are manufactured with pre-installed site specific software and have integrated 24vDC power supplies for safe operation.

These are connected as MODbus slave devices and can be controlled via MODbus from most capable BEMS systems. Alternatively the i-Window systems can be interfaced through our pre-configured MID-IMC Intelligent Master Controller with BACnet MSTP gateway capability.
